A new open-source tool called Cursor Bridge appeared on Hacker News this week, promising to remove Claude usage caps for anyone already paying for Cursor.
The project lives at hkc5/cursor-bridge. Early discussion reached 15 points and 18 comments, with users testing whether the bridge actually bypasses Anthropic rate limits while staying inside Cursor's paid tier.
What It Is
Cursor Bridge acts as a local proxy between the Cursor editor and Anthropic's Claude models. It re-uses the authentication tokens Cursor already holds, routing requests through the same subscription instead of requiring a separate Anthropic API key.
The tool runs as a lightweight Node process on the user's machine. Once started, Cursor points at localhost instead of the official Anthropic endpoint.
How to Try It
Install and run the bridge with three commands:
git clone https://github.com/hkc5/cursor-bridge
cd cursor-bridge
npm install && npm start
Then update Cursor settings to use http://localhost:8787 as the Anthropic base URL. No API key change is needed.
The README lists support for Claude 3.5 Sonnet and Claude 3 Opus. Users report the proxy stays active as long as the Cursor subscription remains valid.
Pros and Cons
- Removes per-hour and per-day Claude call limits for Cursor subscribers
- Requires no extra Anthropic billing account
Runs entirely locally with open-source code
Still depends on Cursor's upstream quota; the bridge cannot create capacity that does not exist
Adds one extra local process and potential latency
Violates Cursor's terms of service according to multiple HN comments
Alternatives and Comparisons
Direct Anthropic API access, Continue.dev with separate keys, and raw Cursor usage are the main options.
| Approach | Cost Model | Rate Limits | Setup Complexity |
|---|---|---|---|
| Cursor Bridge | Cursor subscription | Cursor's shared pool | Low (local proxy) |
| Anthropic API direct | Pay-per-token | Strict per-key | Medium |
| Continue.dev + key | Separate API bill | Per-key | Medium |
| Stock Cursor | Subscription | Cursor's shared pool | None |
Cursor Bridge is the only option that keeps everything inside one existing subscription without additional keys.
Who Should Use This
Developers already paying for Cursor Pro who hit Claude limits daily will see the clearest benefit. Teams that need strict compliance or cannot accept terms-of-service risk should skip it. Hobby users on the free Cursor tier gain nothing because the bridge still requires an active paid subscription.
Bottom Line / Verdict
Cursor Bridge delivers exactly what its name promises: unlimited Claude generations inside the Cursor editor for the price of one subscription, provided users accept the added local component and terms risk.
The project remains early-stage, with the GitHub repo showing active commits but no formal benchmarks yet. For heavy Cursor users, it is the simplest current workaround.
