Cursor alternatives: two projects reviewed with MegaLens
9 October 2026 note. Prices and models at the time of writing; see /pricing for current.
April 2026
In April 2026, we added MegaLens reviews to two projects: an AI Email Drafter built with Claude Code and a PR Description Drafter built with Cursor. MegaLens returned findings beyond each tool's own review. The observations below apply to those projects.
What these observations cover
The two tools reviewed different projects. These observations do not establish how switching editors would affect review quality, or how other tools would perform.
What we actually tested
For each project, we compared the tool's own review with a MegaLens review. The table records the findings returned in those runs.
| Claude Code AI Email Drafter | Cursor PR Drafter | |
|---|---|---|
| IDE’s own review | 12 items | 23 findings |
| MegaLens review | 15 findings | 45 findings |
| Difference | 12 of the 15 not on Claude’s list (3 overlapped) | 22 more findings (45 vs 23) |
| Critical findings | 2 in MegaLens’s 15, both new | went from 3 to 7 |
| Time | not recorded | 7 min |
Claude Code's own list had 12 items, and 12 of MegaLens's 15 findings were not on it. Cursor's own review found 23 findings; MegaLens returned 45.
What MegaLens found in Cursor's plan
The PR Description Drafter is a service that watches git branches, generates PR descriptions via AI, and creates draft pull requests on GitHub. Real tool, real threat surface. Cursor Agent reviewed the 493-line engineering plan and caught 23 issues. Good review. MegaLens returned 45 findings on the same plan.
Some highlights from the 45:
The tool shells out to "git diff" and "git log". Repository .gitconfig can define custom diff tools and credential helpers that run arbitrary code.
Config parsed without safe-load. Unsafe YAML constructors can trigger code execution when the daemon reads its config file.
Fixed port for the OAuth callback. Any program on the same machine can race to bind that port and steal the GitHub authorization code.
Adding a review tool to Cursor
In the PR Description Drafter project, we called MegaLens from inside Cursor to get a review from other models.
Cursor supports MCP (Model Context Protocol) servers. These are tools that your IDE can call during a session. You install them once, and they become available as commands. MegaLens is one of these tools.
When you run a MegaLens review from inside Cursor, MegaLens selects up to four AI models from different companies. Each one reviews your code on its own. A judge then checks each finding against the code and marks it verified only when it can quote the code that proves it.
The result comes back into Cursor. You never leave your editor. Results name the reviewing models that answered. MegaLens reviews. Your IDE decides what to change.
Choosing an editor
If review quality is your reason to consider another editor, compare its findings on your own project. Our two project observations do not predict the result of switching to Windsurf, Claude Code or Copilot.
How to set it up in Cursor
MegaLens installs as an MCP server. Setup is a few steps:
- Create a free account at megalens.ai
- Follow the MCP setup guide to add MegaLens to Cursor
- Run
megalens_debateon your code from inside Cursor
Your first review is free, with no card and no key. After that, pick a plan with reviews included, from $19 a month, or pay as you go.
It also works with Claude Code, Codex CLI, Gemini CLI and Lovable, and with any tool that supports OAuth MCP connectors, such as ChatGPT and Claude.ai. GitHub Copilot is coming soon.
