Ellipsis does one job: it lives in GitHub and reviews pull requests, flagging likely bugs, security issues, and style-guide violations you write in plain English, then offers fix code and can make small edits from PR comments. The standout claim, backed by its own data, is a multistage filtering pipeline aimed squarely at the biggest gripe about AI reviewers, false positives.
Credibility markers are decent for a 2024 startup: YC W24, $2M seed, SOC 2, and installs in more than 67,000 GitHub repos, with free use on public repos that makes it easy for open-source maintainers. The hard limit is platform lock-in, GitHub only, no GitLab, Bitbucket, or Azure DevOps as of 2026, and it competes directly with CodeRabbit and Greptile on narrow ground. Treat it as an always-on first-pass gate, not a replacement for human review. A clean, low-friction pick for GitHub-native teams.
What people say
Founded in 2024 by Nicholas Moy and James Murdza out of Y Combinator's W24 batch on $2M in seed funding, Ellipsis has grown into a GitHub App installed across more than 67,000 repositories. Its scope is deliberately narrow: automate the first pass of code review so humans see cleaner PRs. Reviews on WeavAI, SourceForge, Product Hunt, and DECODE consistently frame it as a reviewer, not a writer, the counterpart to Copilot rather than a competitor.
The headline metric in its own materials is a 13% average acceleration in merge speed. The feature reviewers care about most, though, is the multistage Filtering Pipeline. Because false positives are the number-one complaint about AI reviewers generally, Ellipsis leans on this pipeline to keep noise down, and independent write-ups give it a comparatively low false-positive reputation, one directory scores it 8.3 out of 10 and recommends it specifically for teams that value that.
What users like: reliable detection of logic errors, PR summaries, natural-language style guides that get enforced automatically, and roughly 10-minute onboarding. Open-source maintainers highlight that public repos are free, so community contributions get reviewed without cost. Q&A on PRs and the ability to make small edits in response to comments come up as time-savers.
The consistent caveats are structural rather than quality complaints. As of 2026 Ellipsis supports only GitHub, ruling out GitLab, Bitbucket, and Azure DevOps shops entirely. It holds SOC 2 certification and clears code from its private AWS VPC after each task, which enterprise reviewers note approvingly, though some coverage lists it at Type I rather than Type II. And like every AI reviewer, it produces occasional misses and noise, so reviewers advise treating it as a gate rather than the final word.
Pricing is simple: free for public repositories, then $20 per developer per month for private repos on the Developer plan, which includes reviews on every commit, PR summaries, unlimited codegen, and Q&A. That low barrier, paired with the false-positive focus, is why coverage repeatedly calls it a serious option for GitHub-based teams with a real review burden. No ASEAN-specific provisions; usable globally.
