Greptile vs Mo

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Greptile starts at $30, Mo at $49. Only Greptile has a free tier. Only Greptile ships a public API.

GreptileIndexes the whole repo, then reviews pull requests with cross-file context rather than diff-only context.MoTurns an approval given in Slack or Jira into an automated check that blocks pull requests violating it.

What our research says

Greptile

The full-repo index is the difference that matters - it flags cross-file breakage that diff-only reviewers miss entirely. Billing only for developers who actually got a review that month is a fairer meter than flat per-seat. The 50 credits per seat go quickly on an active team, and $1 per extra review is where the real bill forms.

Pros

  • Indexes the whole codebase, so reviews carry cross-file context
  • Learns from the PR comments your team already writes
  • Seats bill only for developers who actually received a review that period
  • GitHub and GitLab plus an MCP server, an API and a self-hosting option

Cons

  • Credit model means an active repo will exceed the 50 included reviews per seat
  • Overage at $1 per review adds up quietly on a busy month
  • Free tier is capped at a single active developer

Mo

Most code review tools look for bugs; Mo looks for a change that contradicts something a human already decided. That is a narrow but real failure mode — the pricing rule agreed in a thread six months ago that nobody encoded anywhere. Whether it works depends entirely on how well it maps prose decisions onto code, which no trial-free evaluation can tell you.

Pros

  • Approvals captured in place across Slack, Teams, Jira, Linear, Asana, Monday, Azure DevOps and Basecamp
  • Checks run on GitHub, GitLab and Bitbucket pull and merge requests
  • Traces each check back to the decision and the person who approved it
  • 14-day trial with no card required
  • Starter allowance of 100 decisions and 300 checks is legible rather than credit-obscured

Cons

  • $49 per project per month multiplies across repositories
  • Effectiveness rests on translating prose approvals into code checks, which is hard to verify before trialling
  • No API is advertised
  • No launch year or customer references published

Which one fits

Choose Greptile if you need

  • Teams whose bugs come from cross-file coupling rather than local mistakes
  • Enforcing repo-specific conventions through custom rules
  • Orgs that need self-hosted review for code that cannot leave their network

Choose Mo if you need

  • Teams whose decisions live in Slack threads and never reach the codebase
  • Guarding pricing, permission and compliance rules across releases
  • Regulated work needing an audit trail from decision to merge
