bbolt is an embedded, pure-Go key/value database forked from Ben Johnson's Bolt, maintained by the etcd-io project for reliability and stability. It stores data in a single file with B+tree indexing, ACID transactions, and a small fixed API, requiring no separate database server.

Use cases

• embed a simple key/value store in a Go application without running a database server
• persist small-to-medium structured data with ACID transactions in a single file
• store configuration or metadata locally with fast prefix and range scans
• build a reliable local storage layer for tools like proxies or CLI apps
• replace BoltDB with an actively maintained, API-compatible fork

When to choose

• your Go app needs embedded, zero-admin persistent key/value storage
• you want a stable, fixed API and file format with strong consistency guarantees
• you need read/write transactions and nested buckets in a single-file database
• you want a pure-Go dependency with no cgo or external services

When to avoid

• you need SQL, complex queries, or a client-server database
• you need high write concurrency from many processes (single-writer model)
• your dataset is much larger than available RAM and write-heavy workloads dominate
• you need full-text or secondary-index search out of the box
