Pricing
This feature is in beta. Core behavior is stable and ready to try, but some APIs or configuration may still evolve before general availability.
EdgeBase Room runs entirely inside a Durable Object's in-memory state. There is no per-message billing — only DO duration charges while the room is active.
Room works on the Cloudflare Free plan — no credit card required. Free includes Durable Objects with SQLite: 100K requests/day, 13K GB-s/day, and 5 GB storage.
Edge (Cloudflare)
| Resource | Free Plan | Workers Paid ($5/mo) | Overage |
|---|---|---|---|
| DO requests | 100K / day | 1M / month | $0.15 / million |
| DO duration | 13K GB-s / day | 400K GB-s / month | $12.50 / million GB-s |
| DO storage | 5 GB total | 5 GB-month | $0.20 / GB |
Why So Cheap?
- No per-message billing — state updates are broadcast via WebSocket handles inside a single DO
- Hibernation — empty rooms hibernate at $0 duration cost
- No external database — Room state is in-memory with periodic DO Storage persistence
Example: Casual Mini-Game
10K DAU, 3 rounds/day, 4 players/room, 5 state updates/sec/player, average 5 min/game:
| Platform | Approach | Monthly Cost |
|---|---|---|
| Firebase | Database writes + reads | ~$2,700 |
| Supabase | Per-recipient messages | ~$13,500 |
| EdgeBase | DO duration only (~250 concurrent rooms) | ~$10 |
Example: 100 Concurrent Rooms
| Resource | Usage | Cost |
|---|---|---|
| DO requests | ~5M | $0.60 |
| DO duration (5 MB avg × 8h/day) | ~44K GB-s | $0 (included) |
| DO storage (state persistence) | < 1 GB | $0 (included) |
| Total | ~$1/mo |
Self-Hosting
On Docker, Room has no per-message or per-connection cost. All Room DOs run in the same process with in-memory state.
No competing BaaS platform offers ephemeral server-authoritative rooms as a built-in feature. The comparison costs assume equivalent functionality built on their database or messaging primitives.
