Release

Release is a developer-tools platform that provisions on-demand, full-stack ephemeral environments inside your own AWS or GCP cloud accounts. Positioned as a Heroku replacement and a Vercel alternative for full-stack apps, Release turns a repository plus a .release.yaml (or Docker Compose) file into reproducible environments spun up per pull request, per branch, or on demand, with managed Kubernetes clusters, datasets, remote development, and a Release.ai AI sandbox. Teams automate it through a REST Platform API (accounts, apps, environments, deploys, clusters, builds), a GraphQL API, an AI Sandbox API, and a first-party CLI, all authenticated with X-User-Email and X-User-Token headers and described by a canonical OpenAPI contract at https://api.release.com/openapi.json.

Release publishes 9 APIs on the APIs.io network, including Accounts API, Apps API, Builds API, and 6 more. Tagged areas include Company, Developer Tools, Ephemeral Environments, Platform Engineering, and Deployment.

Release’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 25 more developer resources.
