Pros and cons

E2B

Pros

  • 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.

Cons

  • 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

Pros

  • 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.

Cons

  • 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.
