Telegram vs BigBlueButton
A side-by-side editorial comparison of Telegram and BigBlueButton — release velocity, themes, recent moves, and the top alternatives to consider.
Telegram vs BigBlueButton: at a glance
What is Telegram?
Telegram is turning its bot platform into an agent runtime: bots now hire other bots.
Telegram ships large, bundled feature drops every four to eight weeks, mixing consumer polish with platform mechanics in the same release. The consumer half is interface work — an Android redesign, Liquid Glass on iOS, live photos, GIF editing, gift crafting. The platform half is where the direction shows: AI summaries, an AI Editor, bots managed by bots, and now guest AI bots that can be summoned into any chat.
What is BigBlueButton?
BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.

Telegram is turning its bot platform into an agent runtime: bots now hire other bots.
◆ Current state
Telegram ships large, bundled feature drops every four to eight weeks, mixing consumer polish with platform mechanics in the same release. The consumer half is interface work — an Android redesign, Liquid Glass on iOS, live photos, GIF editing, gift crafting. The platform half is where the direction shows: AI summaries, an AI Editor, bots managed by bots, and now guest AI bots that can be summoned into any chat.
◆ Where it's heading
The bot API is being rebuilt as an agent substrate rather than a chatbot toolkit. Bot-to-bot chats and chat automation mean the composition happens inside Telegram instead of on a developer's server, which makes the app the orchestration layer for third-party AI. Identity primitives like Login with Telegram and member tags point at the same ambition: be the account and the runtime, not just the transport.
◆ Prediction
Expect monetization and governance to follow the agent surface — paid or metered access for guest AI bots, plus permission controls over what an automated bot may do inside a group.
BigBlueButton
6.3MEETINGS
BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
◆ Current state
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.
◆ Where it's heading
The LiveKit migration that began in 3.x security patches has culminated in rc.1's 'LiveKit as audio state source' refactor — the legacy audio path is gone. Multi-room sessions with membership-based tokens and automatic token refresh enable scenarios (breakout listen-in, large conferences) that the old bridge couldn't cleanly support. A 4.0 GA release is imminent given the RC cadence.
◆ Prediction
4.0 GA will ship within 2-3 weeks based on the RC pace. Post-GA focus will shift to hardening the LiveKit multi-room session model and expanding BlockNote capabilities (Markdown export landed in beta.4; more collaborative editing features likely next). The successful migration may influence other open-source video conferencing projects still running legacy SFU stacks.
