About Ellipsis

Ellipsis is an AI code review and cloud coding agent platform founded in 2023 and backed by Y Combinator (W24). Founded by Nick Bradford (CEO) and John Lehmann (CTO), Ellipsis raised a $2M seed round in June 2024 and is used by over 90 companies. It started as an AI code review bot that automatically reviews every GitHub pull request, detecting logical mistakes, anti-patterns, and style guide violations with inline comments — and lets developers tag @ellipsis-dev to autonomously implement fixes (with Ellipsis executing and testing the code before submitting). Teams using Ellipsis merge pull requests 13% faster according to its own data, and one customer (Rivo) reported replacing an $80,000 engineering role with a $40/month Ellipsis subscription.

In 2025-2026, Ellipsis evolved from a code review bot into a broader cloud platform for coding agents. The new Ellipsis platform lets teams define Claude Code agents as YAML configuration files committed directly to their repository — specifying the model, triggers (PR events, cron schedules, @ellipsis mentions, production incidents), tools, and budget limits. Deploying or updating an agent is a git push. Agents run in isolated cloud sandboxes with durable conversation threads, cron and event triggers, and full session visibility. Use cases include PR review automation, feature building from GitHub issues, documentation sync, incident investigation, and morning standup summaries.

Ellipsis is SOC 2 Type II certified and does not persist source code — code lives only in a private AWS VPC while a job is processed, then is deleted. It is free for public GitHub repositories and $20/developer/month for private repos. GitHub-only for the core bot; the broader agent platform works with any repository accessible to GitHub.

Key Features

Automated PR code review — detects logical mistakes, anti-patterns, and style guide violations on every GitHub pull request with actionable inline comments
@ellipsis-dev fix trigger — tag @ellipsis-dev in any GitHub PR comment to autonomously implement fixes; Ellipsis executes and tests the code before submitting
Agents as config — define Claude Code agents as YAML files in your repository; deploy to managed cloud sandboxes with a git push for PR review, feature building, and incident investigation
Cron and event triggers — run agents on a schedule (daily changelogs, weekly codebase summaries) or triggered by GitHub events, @ellipsis mentions, and production incidents
Custom style guides in natural language — write your team's coding standards in plain English and Ellipsis enforces them automatically on every PR
Adaptive learning — Ellipsis learns which types of review comments your team values and customizes future reviews to match your preferences
Codebase Q&A — tag @ellipsis-dev with a question right from a GitHub comment to get answers grounded in your codebase without leaving GitHub
Weekly codebase summaries — automatic digests of what changed in your codebase and why, delivered via Slack or email for engineering leadership

Pros

Free for all public GitHub repositories — the easiest no-cost entry into automated AI code review for open-source projects
Agents-as-config approach (YAML in repo + git push) is the most developer-native way to deploy and version-control AI agents
SOC 2 Type II certified with zero code persistence — code never stored after processing, ideal for compliance-sensitive teams
'Replace an $80K engineering role with $40/month' — the strongest ROI claim in the AI code review market, from a real customer (Rivo)
Adaptive learning customizes reviews to your team's preferences over time — reduces noise as it learns what your team values
YC W24 pedigree with $2M seed — early-stage but institutionally validated for serious enterprise consideration

Cons

GitHub-only for the code review bot — no native GitLab, Bitbucket, or Azure DevOps support in the PR review product
Requires admin-level GitHub access to install — often gets stuck in IT approval processes at large enterprises
$20/developer/month adds up for larger teams — a 30-person team pays $600/month, requiring careful ROI calculation
No self-hosting option — pure SaaS on AWS; unsuitable for air-gapped or highly isolated enterprise environments
Cloud coding agents platform is newer and less battle-tested than the core code review product
Weaker analysis of complex architectural or cross-file logic compared to tools with dedicated codebase graph engines like Greptile or Augment Code

Pricing

Ellipsis is free for all public GitHub repositories with no usage limits or credit card required. For private repositories, the Developer plan costs $20/developer/month, billed monthly, with a 7-day free trial and no credit card required for the trial.

The Developer plan includes automated PR code review on all private repos, the @ellipsis-dev fix trigger, custom style guides, adaptive learning, codebase Q&A, weekly summaries, and access to the agents-as-config platform. All plans include SOC 2 Type II compliance and no code persistence.

Enterprise pricing is available for larger teams and adds admin controls, centralized billing, custom compliance requirements, and dedicated support. Contact team@ellipsis.dev or schedule a call with a founder for enterprise pricing.

Frequently Asked Questions

Ellipsis started as an AI code review bot for GitHub but has evolved into a cloud platform for coding agents. The original product automatically reviews every PR and lets developers tag @ellipsis-dev to trigger autonomous bug fixes. The newer Ellipsis cloud platform lets teams define Claude Code agents as YAML config files in their repository and deploy them to run PR reviews, build features, and investigate production incidents in managed cloud sandboxes.

Yes. Ellipsis is free for public GitHub repositories. For private repositories, the Developer plan costs $20/developer/month with a 7-day free trial and no credit card required. There is no permanent free plan for private repos.

Ellipsis is SOC 2 Type II certified. Crucially, it does not persist your source code anywhere — code lives only on their servers in a private AWS VPC while a job is being processed, then is deleted. No code is stored after processing completes.

The Ellipsis cloud platform lets teams define agents as YAML configuration files committed directly to their repository. Each agent specifies which Claude Code model to use, what triggers it (PR events, cron schedule, @ellipsis mentions, production incidents), what tools it has access to, and budget/governance limits. Deploying or updating an agent is as simple as a git push.

Ellipsis was founded in 2023 and backed by Y Combinator (W24). It raised a $2M seed round announced in June 2024. The founders are Nick Bradford (CEO) and John Lehmann (CTO). Over 90 companies use Ellipsis, and teams using it merge pull requests 13% faster according to Ellipsis's own data.
