Quick read
- Free with no card: Giscus, PartyKit.
| Field | LiveKitlivekit.com | Giscusgiscus.app | PartyKitpartykit.io |
|---|---|---|---|
| What it is | Open-source WebRTC selective forwarding unit with a managed global cloud layered on top. Handles multi-party video and audio rooms, screen share, server-side recording, HLS and RTMP egress for broadcasting out, and SIP telephony ingress. Its agents framework adds server-side participants for realtime AI voice. | Comment widget that stores each thread as a GitHub Discussion. You install the giscus app, enable Discussions on a public repo, and a script tag maps each page to a discussion by pathname, URL or og:title. Supports threaded replies, reactions, themes and lazy loading, with no database of your own. | Open-source framework for stateful realtime servers built on Cloudflare Durable Objects. Each 'party' is a server-side class owning a room of WebSocket clients, so presence, chat, cursors and Yjs sync take a few dozen lines. PartyKit announced it was joining Cloudflare in April 2024. |

| Cost tier | mixed | free | free |
| Pricing | Cloud Build free: 5,000 WebRTC minutes/mo, 100 concurrent connections, 1,000 agent session minutes. Ship from $50/mo (150,000 WebRTC minutes then $0.0005/min, 1,000 connections). Scale from $500/mo (1.5M minutes, 5,000 connections). Self-hosting free and open source | Free forever and open source. No hosting cost, no database, no accounts to administer — every thread is stored as a GitHub Discussion in a repository you already own | Individual free: deploy to PartyKit cloud, up to 10 live projects, room storage cleared every 24 hours. Commercial free: deploy to your own Cloudflare account with unlimited projects and custom domains, paying only Cloudflare Workers and Durable Objects usage |
| Why builders pick it | The only serious option that is both a credible hosted product and fully self-hostable, so you can prototype on cloud and move in-house when minutes get expensive. HLS egress turns a four-person panel into a public livestream. | Zero infrastructure, zero cost, zero moderation queue — GitHub handles authentication, spam and abuse reporting for you. For a developer-audience project or a docs site it is the default answer and takes about ten minutes. | You want a multiplayer backend without operating one. npx partykit dev gives a local room server in seconds, and deploying to your own Cloudflare account keeps the bill at raw Workers prices instead of a per-message meter. |
| Watch out for | WebRTC minutes bill per participant, so a 500-viewer live event burns 500 minutes per wall-clock minute — push large audiences to HLS egress rather than into the room. Self-hosting means running TURN servers and scaling the SFU yourself. | Commenters need a GitHub account and must authorise the app, which excludes almost all non-technical readers — usually disqualifying for a general-audience project. The repository must be public, so every comment is public too. | Since the Cloudflare acquisition, momentum has shifted toward Cloudflare's own Durable Objects and Agents SDK — treat PartyKit as a convenience layer that may fold into the platform. Free-tier room storage is wiped every 24 hours, so it is not durable. |
| How to wire it up | npm i livekit-client @livekit/components-react | Paste the generated script tag from giscus.app/#configuration | npm create partykit@latest |
