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 build and runtime logs live from a deployment’s detail page. Secrets are automatically redacted from log output.
