# Runtime costs and limits

Resources include Workers requests, Workers AI planning inference, Durable Object storage/execution, Containers compute, coding inference through the supported AI Gateway/provider arrangement, and GitHub API quotas.

No prices or free-use guarantees are stated here. Check [Workers pricing](https://developers.cloudflare.com/workers/platform/pricing/), [Durable Objects pricing](https://developers.cloudflare.com/durable-objects/platform/pricing/), [Containers pricing](https://developers.cloudflare.com/containers/pricing/), [Workers AI pricing](https://developers.cloudflare.com/workers-ai/platform/pricing/), and [AI Gateway](https://developers.cloudflare.com/ai-gateway/).

## Application limits

| Limit | Value |
| --- | --- |
| Maximum concurrent coding runs / configured container instances | 5 |
| OpenCode timeout | 15 minutes |
| Git command timeout | 5 minutes |
| Collected diff | 120,000 characters |
| Transcript diff display | 20,000 characters |
| stderr tail | 8,000 characters |
| Captured files | 50 |
| Per-file captured contents | 100,000 characters |
| Total captured contents | 500,000 characters |

Sources: `apps/backend/src/runs.ts` (`MAX_CONCURRENT_RUNS = 5`), `apps/backend/src/runtime.ts`, and `apps/backend/src/transcript.ts`. These are application settings, not Cloudflare plan quotas or guaranteed in-memory read bounds. Capture truncation can make publication incomplete.

No measured price or end-to-end cloud usage is available in the dated [`VERIFICATION.md`](/docs/readiness/#evidence-status-2026-09-24); the earlier cost-ratio language is intentionally omitted because it is not evidenced here. Set account budgets and alerts where supported. Clearing history does not stop resource billing, and cancellation requests best-effort cleanup. Verify resource lifecycle and actual charges in your account.
