Frequently asked questions
A contributor is any GitHub user who opens or pushes to a pull request in a Mergegleam-enabled repository within the billing period. Read-only collaborators who leave review comments but don't push code are not counted. The Free tier counts unique contributors per calendar month.
Yes. Both Free and Pro work with private repositories. The GitHub App installation grants Mergegleam read access to the specific repositories you select. Access can be revoked at any time from your GitHub settings.
Mergegleam reads code from GitHub to perform the review and does not persist it to long-term storage. Code is held in ephemeral memory only for the duration of the review (typically under 90 seconds) and is deleted immediately after. Review comments and metadata (PR number, finding type, line number) are stored, but not the source code itself. Full details on our Security page.
TypeScript and JavaScript (first-class support with null safety and type-awareness), Python (type hints respected when present), Go, and Ruby. Mergegleam will read and comment on other languages but the analysis depth is lower. Language coverage is expanding: check the Changelog for the latest additions.
On Pro, configurable ignore rules let you disable specific check categories (e.g., suppress all Info-level comments) or ignore specific file paths (e.g., skip generated code in dist/). Configuration is done via a .mergegleam.json file in the repo root. On Free, all check types run with no customization.
Who built this
Mergegleam started from a familiar problem: CI green, tests passing, then a null dereference in production that a careful reviewer would have caught in thirty seconds. The fix was obvious in retrospect. The gap was in the review process, not the tests.
We built this tool to be the reviewer who doesn't get fatigued, doesn't skip the edge case under time pressure, and shows up on every PR, not just the ones that land when your most careful engineer has bandwidth.
