Current documented limits
| Constraint | Current value | Scope | Verified source |
|---|---|---|---|
| maximum build durationOnly one build is active for a service at a time. | 120 minutes | Build pipeline | RenderAug 22, 2026 |
| pre-deploy durationPre-deploy runs after build and before the new service version starts. | 30 minutes | Eligible services | RenderAug 22, 2026 |
| maximum HTTP response durationClient, proxy, and application timeouts can still be shorter. | Up to 100 minutes | Web services | RenderAug 22, 2026 |
| free web service allowanceThe filesystem is ephemeral and spin-up latency follows idle suspension. | 750 hours/month; spins down after 15 idle minutes | Free web services | RenderAug 22, 2026 |
| free database allowanceBackups and connection pooling are not included on the free database. | 1 GB; expires after 30 days with 14-day grace | Free Postgres | RenderAug 22, 2026 |
How to apply Render limits safely
The monitored baseline covers maximum build duration, pre-deploy duration, maximum HTTP response duration, free web service allowance, free database allowance. Treat these as separate constraints rather than one platform-wide capacity number: a workload can fit one row and still fail another because the plan, model, endpoint, runtime, region, invocation mode, or account scope differs.
- Match the production workload to the exact scope printed beside each value and confirm it in the active Render console, configuration, or response headers.
- Measure the serialized request, token volume, duration, concurrency, storage, or connection demand at realistic percentiles, then preserve headroom for bursts and retries.
- Check every adjacent layer—client, SDK, gateway, proxy, queue, database, and downstream service—for a smaller effective limit before changing architecture.
