Our verdict on Stash
Stash gives teams a self-hosted place to manage application settings, feature flags, and shared configuration as key-value data. It pairs an HTTP API for reading, writing, and deleting keys with a browser-based interface for managing them. Hierarchical slash-separated paths help organize entries, while documented client libraries cover Go, Python, TypeScript/JavaScript, Java, and Rust. Its free model and SQLite or PostgreSQL storage make it relevant to small teams that want to keep configuration on their own infrastructure rather than use a hosted service.
Change control is a notable strength for teams that need more than basic key access. Optional Git-based history records changes and supports point-in-time restore. Prefix-scoped read and write permissions can be assigned to users and API tokens, and secret paths can use encrypted storage with client-side zero-knowledge encryption. An optional in-memory cache is invalidated when keys change, while Server-Sent Events can notify clients of those changes. These options support varied configuration workflows, but teams should evaluate which features they need and account for operating the service themselves.
Stash is a focused choice for teams comfortable maintaining self-hosted software and seeking a free configuration store with API access, a UI, and optional versioning. Its documentation is the listed support channel, so teams seeking another support path should weigh that against their operational needs. The documented API writes and change notifications do not describe staged or percentage-based rollout controls, so teams needing those mechanisms should consider a different fit. Choose Stash for centralized key-value configuration under your own infrastructure; look elsewhere if managed hosting or broader rollout tooling is essential.
