Emendant and Dependabot compared
These tools do different work, and you can use both. Dependabot proposes the version change. Emendant checks your code against supported API changes in that change.
Short answer
Dependabot opens pull requests that update dependency versions. Emendant does not do that. Emendant reads your source code, matches it to changes in its feed, and offers patches for the call sites a supported release changed. Emendant covers only the changes in its feed. It does not cover every package or every breaking change.
Side by side
| Dependabot | Emendant | |
|---|---|---|
| Main job | Propose dependency updates | Find code affected by supported SDK changes |
| Updates dependency versions | Yes. Version updates and security updates. | No. |
| Reads your source code | Not for compatibility. The PR shows release notes. Security updates may show a compatibility score. | Yes. It links each finding to a source location and release evidence. |
| Proposes source changes | No. | Eligible deterministic patches. Assisted fixes need a model provider you select. Some findings have no patch. |
| Checks the change | Your own checks run on the PR. | Runs discovered or configured typecheck and test commands on a patched copy and grades each patch. |
| Where it runs | On GitHub. | As a CLI in your checkout or in CI. |
A Dependabot compatibility score reflects CI results from other public repositories for the same security update. It does not show that your use of the API is correct.
When to use which
- Use Dependabot when you want the update PR to appear on its own.
- Add Emendant when the update crosses a release that changed an SDK API you use, and the SDK is in Emendant's feed. Check supported projects first.
- Use both on the same PR. See Emendant with Dependabot.
Coverage. Emendant reports the changes in its feed. A clean scan does not show that an upgrade is complete. See supported projects and known limitations.
