A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

 
Cobalt
Coding
Cursor
Coding
TaglineAn AI developer with its own cloud computer that writes code in your GitHub repo, runs the tests, and hands you a pull request.AI-first VS Code fork — chat, edit, and agentic coding in one IDE.

Pros
  • Runs a real cloud VM per task, so it can boot Docker, databases and multi-service stacks - not just a Next.js frontend.
  • Delivers work as commits and pull requests on GitHub (or Azure DevOps) rather than pasted code snippets you still have to apply.
  • Live in-browser preview of the running app updates as the agent edits code, so you can click through the feature before merging.
  • Agent-agnostic: pick Codex, Claude Code, Cursor, OpenCode or Pi per task while keeping the same computer, repo and Git workflow.
  • Long-running work continues after you close the tab and is waiting when you come back on any device.
  • Parallel tasks each get isolated computers, so features, refactors and spikes do not fight over your local checkout.
  • Saved computer snapshots let repos with heavy setup skip re-installing dependencies on every task.
  • GitHub credentials are scoped to the task lifetime and are not persisted on the runner.
  • Best-in-class multi-file edits
  • Choice of underlying models
  • Composer agent is genuinely useful
  • Tab completion is faster than Copilot
Cons
  • No public pricing on the marketing site at time of review, and using Codex requires you to attach your own paid ChatGPT account.
  • Cloud-only execution: no way to run the agent against a local checkout or an internal repo that cannot be reached from Cobalt's network.
  • Only GitHub and (as of the July 2026 launch note) Azure DevOps are wired up - GitLab, Bitbucket and self-hosted Git are not first-class.
  • The product is young and iterating quickly (Aug 2026 launch notes still adding core features like per-repo VM sizing), so expect churn.
  • No documented public API for programmatic task orchestration - workflow is driven from Cobalt's own chat UI.
  • Closed-source SaaS with your repo cloned onto a third-party VM, which is a non-starter for teams under strict data-residency or on-prem rules.
  • Heavier than vanilla VS Code
  • Pricing creeping up
  • Some extensions lag VS Code
