Same category, persistent container hosting with attached databases. Railway is excellent on developer ergonomics and bills by usage. Its agent surfaces act through your account. PromptShip gives each agent its own identity and environment-scoped token, holds agent-initiated production writes for human approval, records one action ledger, and operates the app, Postgres, cache, and ClickHouse as one environment.
