Configuration & secrets
Provide environment variables and secrets to builds and runtime safely.
Secrets & variables
- •Add secrets (API keys, database URLs, tokens) under a project’s Secrets. They’re encrypted at rest and never shown in the UI or logs.
- •For React/static apps, build-time variables are inlined during the build; for Node services they’re available to the running process.
Logs
- •Watch logs live from a deployment’s detail page: build logs for every deploy, Node/Python runtime logs (container stdout/stderr) for server apps, and an Access log for Static/React apps (failed and non-GET requests, since static apps run no process).
- •Secrets are automatically redacted from all log output. See “Deploy with the API” for the matching API endpoints and a troubleshooting reference.
