- Model- and framework-agnostic, with Python and JavaScript SDKs.

### Choose Greptile if

- You want a tool built for automated pull request review on large codebases, enforcing team coding standards, feeding review findings to coding agents.

## E2B strengths

- Hardware-level isolation through Firecracker microVMs rather than shared-kernel containers.
- Model- and framework-agnostic, with Python and JavaScript SDKs.
- Pause, resume and fork of sandboxes (up to 100 forks) suits parallel agent runs and evaluations.
- Free Hobby tier with $100 in credits and no credit card.
- Self-hosting and BYOC options for enterprises, plus SOC 2 Type II compliance.

## E2B limitations

- Pro costs $150/month before usage, a large step up from the one-time Hobby credit.
- No GPU support; sandboxes are limited to 8 vCPUs and 8 GiB RAM.
- Hobby sessions are capped at 1 hour of continuous runtime.
- Enterprise carries a stated $3,000/month minimum.

## Greptile strengths

- Reviews use a graph index of the whole repository, so findings can cover impact beyond the changed lines.
- Plain-English custom rules and learning from past pull request comments adapt reviews to team standards.
- Works with GitHub, GitLab and Bitbucket, and hands findings to Claude Code, Cursor, Codex or Devin.
- Self-hosting and air-gapped deployment are available for regulated organizations.
- Free tier for one developer, free use for qualified open source, and 50% off for early startups.

## Greptile limitations

- Third-party comparisons report more false positives than some competitors; one competitor-run test claims nearly 60% of comments were nitpicks or false positives, which should be read as a rival's claim.
- Pro costs $30 per seat per month and extra credits cost $1 each, with Plus and Apex reviews using 3 and 10 credits.
- Self-hosting, SSO/SAML and GitHub Enterprise support require the custom-priced Enterprise plan.
- Focused on pull request review only; it is not an editor or coding assistant.
