DiffCI Core
$0forever
The engine, CLI, MCP server, pre-push hook and GitHub Action. Affected-check selection with full-suite fallback when DiffCI is unsure. No account needed.
Pricing
Free to run locally. Paid when a team needs one view of every agent and repository.
DiffCI Core selects and runs the checks a change affects, on your machine or in CI, and sends nothing by default. DiffCI Cloud adds what a single checkout cannot see: shared history, per-agent fleet analytics, policy and an audit trail.

What you are not paying for
Test selection itself is free and stays in the open-source core. DiffCI Cloud does not hide correctness behind the paywall, and its policies never change CI on their own: the merge gate only blocks merges when an organization turns it on and makes its check required.
DiffCI Cloud is in early access. Prices are in US dollars, billed monthly through Lemon Squeezy as merchant of record, and taxes are added where they apply. See data handling for what the hosted service stores.
