Hangar runs your apps and databases with no servers to manage. Connect a repo, or let your AI agent do it over MCP from Claude Code, Cursor or any client. The agent deploys, then reads the same logs, metrics and traces you see, finds what broke in production and ships the fix. Builds use Railpack, the builder Railway uses, so most repos move with no code changes. Postgres, MySQL, MongoDB, Redis and libSQL run next to your app, with usage billing and hard spend limits per project.
