MergeSafe vs Macroscope
Last updated .
How is MergeSafe different from Macroscope?
Macroscope reviews your code and reports on what your team ships. MergeSafe reviews it too, then decides whether it is safe to merge, and checks every package a pull request adds for known vulnerabilities and malware, which Macroscope’s docs do not cover.
Checked November 2026 against Macroscope’s own pricing and docs (links below). Both products work on GitHub only and charge no seats.
At a glance
| Macroscope | MergeSafe | |
|---|---|---|
| Pricing | Usage-based, prepaid. A review costs $0.025 to $0.20 per KB of diff, by mode, so it grows with the diff. The 10 KB minimum makes the smallest review $0.25 to $2.00. Commit summaries are $0.05 each. Agents use credits. | A set price per review for each level, from a prepaid balance. See Pricing. |
| Seats | None. | None. |
| Free | $100 of usage for a new workspace, and 1,000 agent credits a month. | $20 to start. The dependency gate is free on every repository. |
| Platforms | GitHub only. | GitHub only. |
| Dependency checks | Not described in its docs. | The dependency gate flags known-vulnerable, malicious and made-up npm and PyPI packages. |
| Merge check | Check Run Agents you write in markdown; one can block a merge when set to fail and made required. Approvability auto-approves low-risk pull requests and says it is not a fail-closed gate. | The mergesafe-review check fails while a P0 or P1 finding is open. |
| Production errors | Its agent can read Sentry issues (beta). | Sentry errors become GitHub issues; tested fixes are optional. |
| CLI and agents | A CLI and plugins for coding agents, with a review-and-fix loop. | Findings over MCP and the API. |
Where Macroscope is strong
- Knowing what shipped. Commit summaries, executive summaries, weekly digests and productivity metrics, delivered to Slack.
- Custom checks. Check Run Agents let you write your own GitHub checks in plain markdown.
- Spend controls. Per-review and per-pull-request caps, a monthly limit, and a prepaid balance that never expires.
- Fixes. Fix It For Me opens a pull request and iterates until CI passes.
Where MergeSafe is different
- Supply chain on every pull request. The dependency gate checks each new or changed package for known vulnerabilities, malware, lookalike names and names the registry has never seen. It runs with or without a review, free.
- A gate out of the box. The merge-readiness score and its check come with every review; there is nothing to write first.
- A set price per review. Each level has one price up to 2,000 hand-written lines; between 2,000 and 5,000 hand-written lines MergeSafe asks first and charges 1.5 times. Small follow-ups on Essential and Strong are half price.
- After the merge. The advisory check tells you when a new advisory affects your code, and Sentry errors can become tested fixes.
Which should I pick?
Pick Macroscope if you want reviews plus reporting on what your team ships, or you want to write your own checks. Pick MergeSafe if you want one gate before merge that also covers the packages a pull request adds, at a set price per review.
