Zoom\u2019s 40-minute limit is designed to push small teams toward the $15\/month Pro tier. Slack\u2019s 90-day message history cap means institutional knowledge disappears \u2014 and recovering it requires upgrading. The real cost of these tools isn\u2019t monetary; it\u2019s the organizational friction created when data vanishes or calls get cut off at the worst moment.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\">Self-hosted solutions like TrueConf Server Free or Rocket.Chat sidestep this entirely. You control your data, there\u2019s no subscription cliff to fall off, and the limits are technical (hardware capacity) rather than artificial (vendor-imposed).<\/p>\n<\/div>\n<style>\n\t.accent-card {<br \/>\t    \/*background: url(\/images\/common\/backgrounds\/blue-semi-transparent-rounded-squares-1138-x-510.svg) 50% 50% \/ cover no-repeat;*\/<br \/>\t    border-radius: 12px;<br \/>\t\tpadding: 40px 28px;<br \/>\t}<br \/>\t@media screen and (max-width: 576px) {<br \/>\t\t.accent-card {<br \/>\t\t\tpadding: 24px;<br \/>\t\t}<br \/>\t}<br \/><\/style>\n<div style=\"background: #00B3CD; border-radius: 12px; padding: 24px;\">\n<h2 class=\"h4--main h4--thick white-text center-text ui-mb-xs-3\">Self-Hosted Team Messenger with Video Conferencing<\/h2>\n<p class=\"primary-smallest-text white-text center-text ui-mb-sm-3\">A cutting-edge team collaboration server with personal and group chats, UltraHD video conferences, and advanced AI-powered features \u2014 <b>free for up to 1,000 users<\/b>!<\/p>\n<div class=\"button-group-container button-group-container--center\"><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate default-button__download-icon default-button--left-icon white-icon\" role=\"link\" href=\"https:\/\/trueconf.com\/downloads\/trueconf-server\/en\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><br \/>\n<span class=\"default-button__text white-text\">Dowload Now!<\/span><br \/>\n<\/a><a class=\"primary-smallest-text to-page to-page--rarr white-icon white-text\" role=\"link\" href=\"https:\/\/trueconf.com\/\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Learn more<\/a><\/div>\n<\/div>\n<h2 class=\"h4--main h4--thick black-text ui-mb-xs-3 ui-mt-md-1\">Detailed App Reviews<\/h2>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">1.

class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">2. Zoom<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Zoom&#8217;s free plan still works well for individuals and small groups holding shorter meetings. The 40-minute limit on group calls (three or more participants) is the main constraint, though one-on-one calls remain unlimited.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: 100 participants, whiteboard, screen sharing, AI meeting summaries (limited), breakout rooms.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: Beyond the time cap, Zoom has progressively moved features out of the free tier over recent years. Cloud recording, for instance, requires a paid account.<\/p>\n<div style=\"display: flex; align-items: center; justify-content: space-between; flex-wrap: wrap; gap: 12px; background: #00B3CD; border-radius: 12px; padding: 12px 16px;\">\n<h5 class=\"primary-small-text white-text\">Compare TrueConf with Zoom!<\/h5>\n<p><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate default-button__forward-icon default-button--right-icon white-icon\" role=\"link\" href=\"https:\/\/trueconf.com\/trueconf-vs-zoom.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><br \/>\n<span class=\"default-button__text white-text\">Compare<\/span><br \/>\n<\/a><\/p>\n<\/div>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">3. Microsoft Teams<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Teams&#8217; free personal plan is more generous than many people realize. Group video meetings run up to 60 minutes with up to 100 participants, and chat history is unlimited. If your organization already uses Microsoft 365, the paid version is often already included in your subscription.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Unlimited chat, 5GB cloud storage, file sharing, real-time document collaboration.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: The free plan lacks meeting recordings and some admin controls. Large enterprises tend to hit the feature ceiling quickly.<\/p>\n<div style=\"display: flex; align-items: center; justify-content: space-between; flex-wrap: wrap; gap: 12px; background: #00B3CD; border-radius: 12px; padding: 12px 16px;\">\n<h5 class=\"primary-small-text white-text\">Compare TrueConf with Microsoft Teams!<\/h5>\n<p><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate default-button__forward-icon default-button--right-icon white-icon\" role=\"link\" href=\"https:\/\/trueconf.com\/teams-alternative.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><br \/>\n<span class=\"default-button__text white-text\">Compare<\/span><br \/>\n<\/a><\/p>\n<\/div>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">4. Slack<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Slack&#8217;s interface remains the standard against which most team chat apps are measured. Channels, threads, and integrations give it a structure that scales well for knowledge work.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: 10 app integrations, 10 workflows per month, audio\/video clips (Clips feature), 1:1 audio\/video calls, 90-day message search.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: The 90-day message history cap is a genuine operational problem for teams relying on Slack as a knowledge base. Conversations and decisions simply disappear. This is the single biggest reason teams outgrow the free plan.<\/p>\n<div style=\"margin: 24px 0; padding: 12px 0; border-top: 1px solid #E5E7EB; border-bottom: 1px solid #E5E7EB;\"><b><\/b><b><a href=\"https:\/\/trueconf.com\/blog\/reviews-comparisons\/slack-vs-zoom\" target=\"_blank\" rel=\"noopener\">\u2192 Read also: Slack vs. Zoom vs. TrueConf: A Comprehensive Comparison<\/a><\/b><\/div>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">5. Google Chat<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">For teams already inside the Google ecosystem, Chat is the path of least resistance. It&#8217;s clean, reliable, and integrates directly with Gmail, Drive, Calendar, and Meet.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Direct messages and Spaces (group channels), Google Meet video calls, rich text formatting, reactions.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: Without a Google Workspace subscription, some administrative features are missing, and external guest access is limited.<\/p>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">6. Signal<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Signal is a messaging app, not a workplace collaboration tool. But for organizations handling sensitive information \u2014 legal teams, journalists, medical professionals \u2014 it fills a specific gap no other free tool matches.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: End-to-end encrypted messages, voice and video calls, group chats, disappearing messages, no ads, no data collection.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: No desktop-only deployment, no admin management, not designed for large team workflows.<\/p>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">7. Telegram<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Telegram&#8217;s free tier is unusually generous. Group chats can hold up to 200,000 members, file sharing goes up to 2GB per file, and message history is stored indefinitely in the cloud.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Unlimited messages, voice\/video calls, bots API, channel broadcasting, cross-device sync.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: Encryption is not end-to-end by default (only in &#8220;Secret Chats&#8221;). Standard messages are encrypted in transit but accessible on Telegram&#8217;s servers. This is an important distinction for compliance-sensitive environments.<\/p>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">8. Rocket.Chat<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Rocket.Chat is an open-source Slack alternative. Self-hosted deployment is free with no user limits, and the community edition includes most features needed for workplace communication.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Unlimited messages and users (self-hosted), channels, direct messages, file sharing, video calls (via Jitsi integration), omnichannel features.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: Requires server setup and maintenance. The cloud-hosted free plan has a cap of 25 registered users.<\/p>\n<div style=\"display: flex; align-items: center; justify-content: space-between; flex-wrap: wrap; gap: 12px; background: #00B3CD; border-radius: 12px; padding: 12px 16px;\">\n<h5 class=\"primary-small-text white-text\">Compare TrueConf with Rocket.Chat!<\/h5>\n<p><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate default-button__forward-icon default-button--right-icon white-icon\" role=\"link\" href=\"https:\/\/trueconf.com\/rocket-chat-alternative.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><br \/>\n<span class=\"default-button__text white-text\">Compare<\/span><br \/>\n<\/a><\/p>\n<\/div>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">9. Jitsi Meet<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Jitsi is the go-to option when you need a video call immediately, with no accounts, no downloads, and no expiration timer. Just create a room name and share the link.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Unlimited meeting duration, no participant cap on self-hosted, screen sharing, chat, recording (self-hosted), browser-based access.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: The public meet.jit.si server has become less reliable under load. For consistent quality, self-hosting is the better path.<\/p>\n<div style=\"display: flex; align-items: center; justify-content: space-between; flex-wrap: wrap; gap: 12px; background: #00B3CD; border-radius: 12px; padding: 12px 16px;\">\n<h5 class=\"primary-small-text white-text\">Compare TrueConf with Jitsi!<\/h5>\n<p><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate default-button__forward-icon default-button--right-icon white-icon\" role=\"link\" href=\"https:\/\/trueconf.com\/trueconf-vs-jitsi.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><br \/>\n<span class=\"default-button__text white-text\">Compare<\/span><br \/>\n<\/a><\/p>\n<\/div>\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3 ui-mt-md-1\">10. Discord<\/h3>\n<p class=\"primary-medium-text ui-mb-sm-1\">Discord started as a gaming communication platform and has since become a serious option for communities, creator groups, and distributed teams. Voice channels stay open continuously, which creates a different dynamic from scheduled meetings \u2014 more like an open office.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Free tier includes<\/strong>: Unlimited text, voice, and video channels, screen sharing, 8MB file uploads, 25 video participants per call, server communities up to 10M members.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\"><strong>Limitation to watch<\/strong>: File upload limit (8MB) becomes annoying quickly. Boosting a server with Nitro subscriptions unlocks higher limits, but it&#8217;s not required for basic use.<\/p>\n<div style=\"background: #F4F6FA; border-top: 3px solid #00BCD4; padding: 20px 24px 24px 24px; margin: 28px 0; border-radius: 8px;\">\n<p class=\"primary-medium-text ui-mb-sm-1\"><b>Unique Insight #2: Why On-Premises Still Wins for Regulated Industries<\/b><\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\">Cloud-based free tiers from major vendors (Zoom, Teams, Slack) all share a fundamental characteristic: your data lives on someone else\u2019s infrastructure, subject to their terms of service, their security incidents, and their business decisions. When Slack raised prices in 2023 or when Zoom changed its AI training data policy, organizations had no leverage because their communication history was already locked in.<\/p>\n<p class=\"primary-medium-text ui-mb-sm-1\">For healthcare, government, and financial services, on-premises communication isn\u2019t just a preference \u2014 it\u2019s often a compliance requirement. TrueConf Server Free, Rocket.Chat, and Jitsi (self-hosted) cover this space without requiring a paid enterprise contract. The upfront effort of setting up a server is a one-time investment that pays off every month you\u2019re not writing a check to a SaaS vendor.<\/p>\n<\/div>\n<div class=\"grid-layout\">\n<div class=\"grid-layout__col-2\">\n<div class=\"grid-layout__item grid-layout__item--md grid-layout__item--color\">\n<h3 class=\"h5--main h5--thick black-text ui-mb-xs-3\">The Department of Health of Ho Chi Minh City|Case Study<\/h3>\n<p class=\"primary-small-text\">TrueConf video collaboration solution connected more than 100 hospitals in Ho Chi Minh and allowed converting quarterly medical examination and treatment briefings between the Department of Health and hospitals into online mode. 660 employees of the City Oncology Hospital can now collaborate with one another without any barriers, increasing both speed and efficiency of communications.<\/p>\n<p><a class=\"default-button default-button--sm default-button--orange default-button--rounded default-button--truncate white-text\" role=\"link\" href=\"https:\/\/trueconf.com\/blog\/success-stories\/the-department-of-health-of-ho-chi-minh-city\" target=\"_blank\" rel=\"noopener\"><br \/>\n<span class=\"default-button__text\">Success story<\/span><br \/>\n<\/a><\/p>\n<\/div>\n<div class=\"grid-layout__item\"><img decoding=\"async\" title=\"ClinicTracker Success story\" src=\"https:\/\/vietnamtravel.com\/images\/2020\/12\/Hospital-for-Tropical-Diseases.jpg\" alt=\"Karnataka Bank|Case Study\" \/ loading=\"lazy\"><\/div>\n<\/div>\n<\/div>\n<h2 class=\"h4--main h4--thick black-text ui-mb-xs-3 ui-mt-md-1\">How to Choose: A Decision Framework<\/h2>\n<ul class=\"ui-list ui-list--medium\" style=\"margin-bottom: 18px;\">\n<li class=\"ui-list__item ui-list__item--disc\"><strong>If you need video calls as the primary use case<\/strong>: Start with TrueConf Server Free (if you have IT support) or Zoom free (if you don&#8217;t).<\/li>\n<li class=\"ui-list__item ui-list__item--disc\"><strong>If team messaging is the priority<\/strong>: Slack or Google Chat, depending on whether your team already uses Gmail and Drive.<\/li>\n<li class=\"ui-list__item ui-list__item--disc\"><strong>If data privacy is non-negotiable<\/strong>: TrueConf (on-premises), Signal (mobile), or Rocket.Chat (self-hosted).<\/li>\n<li class=\"ui-list__item ui-list__item--disc\"><strong>If you need a community or open channel for external people<\/strong>: Telegram or Discord.<\/li>\n<li class=\"ui-list__item ui-list__item--disc\"><strong>If you want zero setup for occasional meetings<\/strong>: Jitsi Meet.<\/li>\n<\/ul>\n<section id=\"faq\">\n<h2 class=\"h3--main h3--thick black-text ui-mb-md-1\">FAQ<\/h2>\n<div class=\"faq__container ui-mb-md-1\">\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">What is the best free app for video calls with large teams?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">TrueConf Server Free supports up to 1,000 simultaneously logged-in users and offers video conferencing in 4K without time limits. For cloud-only options, Microsoft Teams free allows 100-person calls for up to 60 minutes.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">Is there a free communication app with no time limits on group calls?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">Yes \u2014 TrueConf Server Free and Jitsi Meet (especially on a self-hosted instance) have no call duration limits. Zoom&#8217;s free plan caps group calls at 40 minutes, and Microsoft Teams free caps them at 60 minutes.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">Which free communication app is the most secure?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">For maximum privacy, Signal uses end-to-end encryption for all messages and calls by default. For corporate environments where data must stay on internal servers, TrueConf Server Free deployed on-premises offers the strongest organizational control.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">Can I use free communication apps for a business with 50+ employees?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">Yes. TrueConf Server Free supports up to 1,000 simultaneous users. Rocket.Chat self-hosted and Jitsi self-hosted also have no user caps. Cloud-based free tiers from Zoom or Teams start to show their limitations at this scale, particularly around admin controls and storage.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">Do any free communication apps work without an internet connection?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">TrueConf Server Free can operate entirely within a closed LAN\/VPN network without internet access, making it suitable for air-gapped environments. No public cloud-based free app supports this use case.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq__item\">\n<p class=\"faq__question h4--main h4--thick black-text hyphens--auto margin--not\">Are free communication apps safe to use for sensitive business data?<\/p>\n<div class=\"faq__answer\">\n<p class=\"primary-medium-text margin--not\">It depends on where data is stored. Cloud apps (Zoom, Slack, Teams) store data on vendor servers under their privacy policies. Self-hosted solutions like TrueConf, Rocket.Chat, and Jitsi keep all data on infrastructure you control. For genuinely sensitive data, the self-hosted route is the more defensible choice.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<div class=\"divider\"><\/div>\n<div class=\"accent-note accent-note--special ui-mb-sm-1\">\n<p class=\"primary-medium-text\"><strong><i>About the Author<\/i><\/strong><br \/>\n<i>Olga Afonina is a technology writer and industry expert specializing in video conferencing solutions and collaboration software.
