Quick read
- Free with no card: Giscus, PartyKit.
| Field | Liveblocksliveblocks.io | Giscusgiscus.app | PartyKitpartykit.io |
|---|---|---|---|
| What it is | Hosted realtime collaboration infrastructure covering presence, multiplayer state, a Yjs-compatible sync backend and a full Comments product with threads, mentions and email notifications. Ships pre-built React components alongside lower-level primitives, so threaded annotations can be attached to an article, editor or media player without running a socket server. | 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. |
| Category | Realtime, comments & collab | Realtime, comments & collab | Realtime, comments & collab |
| Cost tier | mixed | free | free |
| Pricing | Free: unlimited MAU, unlimited rooms, 10 projects, 10 simultaneous connections per room, 10 MB storage per room, 30-day version history. Pro $25/mo billed annually with $30 monthly credits. Team $500/mo with $600 credits. Enterprise custom | 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 | Fastest route to Google-Docs-style presence plus inline comments on a page. The Comments product alone replaces a homegrown thread, mention and notification stack, and the free tier has no monthly-active-user cap at all. | 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 | The free plan caps simultaneous connections at 10 per room, which a busy live article thread will exceed. Paid plans meter usage against monthly credits rather than a flat seat price, so a traffic spike converts directly into overage. | 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 @liveblocks/client @liveblocks/react | Paste the generated script tag from giscus.app/#configuration | npm create partykit@latest |
