Backpatch complements Dependabot, Renovate, Snyk, and OSV.
Those tools identify vulnerable dependencies or propose updates. Backpatch identifies whether the temporary override you added is still necessary. If you are choosing between them, you have the wrong frame — they run at opposite ends of the same incident.
The lifecycle of one override
- 01
A scanner flags a transitive dependency
Dependabot, Snyk, or npm audit — reading OSV or GitHub Advisories.
- 02
No parent release exists yet
The direct fix is blocked on someone else’s release cycle.
- 03
You pin the safe version yourself
An overrides, resolutions, or pnpm.overrides entry closes the exposure now.
- 04
The parent quietly catches up
Weeks or months later, a release ships the safe transitive version.
- 05
…and nothing tells you
This is where Backpatch runs. The scanner is quiet — because your override made it quiet.
Tool by tool
Dependabot
What it does — Watches your manifests and opens pull requests when a dependency has a newer or non-vulnerable version.
Where Backpatch picks up — Bumps the parent, but says nothing about the override you added while waiting for that bump.
Renovate
What it does — The same, with far more configuration — grouping, schedules, automerge rules, custom managers.
Where Backpatch picks up — Manages the versions you declare. An override is a resolution instruction, not a dependency it tracks.
Snyk
What it does — Finds vulnerable packages across your tree, prioritizes by reachability, and suggests fixes.
Where Backpatch picks up — Reports the override as an effective fix. It has no reason to revisit a finding that is already closed.
OSV.dev
What it does — The open advisory database — which versions of a package are affected, and which are patched.
Where Backpatch picks up — Answers what is vulnerable, not whether your specific parent has caught up. Backpatch reads OSV to answer that.
What Backpatch is not
It is not a vulnerability scanner, and it is not a replacement for one. It does not monitor your repositories, open upgrade pull requests, or tell you about new advisories. If you removed Dependabot and kept Backpatch, you would find out about nothing.
It answers one question the others leave open: for an override you already have, has the parent dependency moved far enough that you can delete it?
Using them together
- Keep your scanner as the thing that finds new problems.
- Keep the override as the right emergency fix — it closes exposure in minutes.
- Run Backpatch after upgrades land, so the pins do not outlive their reason.
