Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
PartyKit
- Documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
- Commercial free tier requires deploying to the user's own Cloudflare account, adding setup complexity.
- Storage on the free Individual plan clears every 24 hours, limiting it to prototyping rather than persistent production data.
- Smaller ecosystem and community than more established realtime infrastructure providers.
Coder
- Premium plan pricing is not published and requires contacting sales.
- Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs.
- High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls.
