Stop guessing which one. Put them side by side.

The grid says what these tools are. This says what builders did about it — one decision per person, changeable whenever you change your mind.

# Tool comparison — Intercom vs Giscus vs PartyKit

Source: Kbaise, a directory of tools that work with Lovable projects.
Pick one and tell me why before writing any integration code.

## Intercom (intercom)
- URL: https://www.intercom.com
- Category: Realtime, comments & collab
- Cost: paid — Essential $29 per seat/mo; Advanced $85 per seat/mo (20 free Lite seats); Expert $132 per seat/mo (50 free Lite seats). Fin AI agent $0.99 per resolved outcome on all plans. No free tier; Early Stage programme offers eligible startups 93% off
- What it is: Full customer communication platform spanning messenger, shared inbox, ticketing, help centre, product tours and outbound campaigns. Its Fin AI agent answers from your help content and is billed per successful resolution rather than per message, and can run standalone on top of another helpdesk such as Zendesk or Salesforce.
- Why builders pick it: The polished incumbent, with the best messenger UX and the deepest reporting in the category. Worth it when reader support is a real revenue function and Fin can deflect the endless subscription, paywall and login questions.
- Trap: Comfortably the most expensive option here: per-seat pricing plus $0.99 per Fin resolution plus pay-as-you-go email, SMS and WhatsApp. There is no free tier, and outbound message volume is billed entirely separately from seats.

## Giscus (giscus)
- URL: https://giscus.app
- Category: Realtime, comments & collab
- Cost: free — 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
- What it is: 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.
- Why builders pick it: 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.
- Trap: 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.
- Wiring: Paste the generated script tag from giscus.app/#configuration

## PartyKit (partykit)
- URL: https://www.partykit.io
- Category: Realtime, comments & collab
- Cost: free — 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
- What it is: 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.
- Why builders pick it: 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.
- Trap: 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.
