What our research says

delta.dev

Delta comes from the team behind the Zed editor and targets the real bottleneck of agent-assisted work: reviewing what an agent changed together with the conversation that produced it. It has moved past the waitlist into a downloadable beta for macOS, Linux, Windows and the web, free with your own keys and $10 a month for hosted models. It is still early-access software, so expect the workflow and limits to keep changing.

Pros

  • Built by the team behind the Zed editor, with the same account and plans
  • Keeps the reasoning and every edit of a thread attached to the code, with revert to any step
  • Free Personal plan works with your own API keys or external agents
  • Desktop builds for macOS, Linux and Windows plus a web version

Cons

  • Still beta, downloaded under an Early Access Agreement
  • Pro includes only $5 of hosted-model tokens a month before usage billing starts
  • Zed's edit predictions are not available inside Delta

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

Which one fits

Choose delta.dev if you need

  • Teams already using Zed who review a lot of agent-written code
  • Developers who want each change tied to the prompt and reasoning behind it
  • People who already pay for model API keys and want a free agent workspace on top

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
