Your Repos

Unify repositories on a single coherent component graph for consistency and speed.

*It's open source and free!

Love The Freedom, Hate The Friction?

A polyrepo gives your teams autonomy, but it comes at a cost.
Dependency hell
Tangled package.json files, phantom dependencies, and versioning conflicts that bring development to a standstill
Code duplication
Shared logic is copied across multiple repositories, leading to maintenance nightmares, inconsistencies, and bugs
Inconsistent tooling
Each team uses its own setup for building, testing, and deploying, creating a fragmented development experience
No discovery & visibility
Code is scattered across countless repositories, making it nearly impossible to find or use for new

Multi-repo Autonomy. Monorepo Sanity.

Get the best of both worlds. Bit provides the discovery, reuse, and dependency control of a monorepo, without sacrificing your team's independence.
Dependency heaven
Control dependencies over a single component dependency graph.
Code reuse
Reuse code across repositories in ease and without compromising independence.
Consistent tooling
Reuse dev tooling and configuration to ensure standards across repositories.
Discovery & Visibility
Turn your codebase into a collection of reusable digital assets.
Collaborate from your project's context
