DoltLite Beta: SQLite fork with Git-style version control, built with 2k agent PRs

DoltLite 0.50.0, now in Beta, is a fork of SQLite that swaps the B-tree storage for a Prolly Tree-backed chunk store, adding Git-style version control to the familiar SQLite interface. The project was built in just five months by a team of AI agents, using about 2,000 pull requests.

What Is DoltLite?

Everything above the B-tree layer — SQL parser, analyzer, file I/O, and test harness — is stock SQLite. The B-tree layer is replaced with a Prolly Tree (content-addressed B-tree) backed by a single file chunk store. That gives you full version control features: branch, merge, diff, rebase, cherry-pick, reset, and remote operations like push, pull, clone, and fetch from a custom remote or DoltHub.

What Beta Means

• Storage Format Stability: The format is now stable after 12 breaking changes. It's been untouched for 57 releases (3+ months). Future changes will have migration paths.
• SQL Compatibility: Passes 100% of sqllogictest (5.8M queries) and 99.46% of SQLite's 892K TCL acceptance tests. The 4,809 divergences are documented and stem from primary key indexing, chunk-based storage, and no WAL/journal.
• Full Version Control: All core Dolt features are implemented locally and remotely. Works with DoltHub as a sync backend.
• Production Performance: In-memory databases are 10% slower on reads, 60% slower on writes vs SQLite. File-backed are at parity on reads, 10% slower on batched writes. Small autocommit writes are 3.1X slower — use batched writes for performance-sensitive work.

Try It

DoltLite Beta is ready for adoption. Daily performance reports are published on GitHub. If you want Git-like version control for your SQLite databases, DoltLite is worth a look.
