Show HN: Sweep – Cursor Tab Alternative for JetBrains IDEs

Hi HN, we’re Kevin and William from Sweep. We’ve spent the last couple of months building a custom tab model (like Cursor/Windsurf) for JetBrains IDEs. You can use the plugin in your favorite IDE via the JetBrains marketplace.

Our autocomplete is aware of your recent changes, has full-codebase context, and is exceptionally fast (200ms P50 latency). We’ve deployed this across regions in us-west, us-east, and eu!

Because we have access to the IDE, we can also use the IDE’s code graph/index to automatically lookup definitions and references across your project. This helps the LLM see the exact definition rather than having to guess.

We’ve also shipped a strong coding agent that runs faster than Claude Code with minimal performance loss.

We’d love to get your thoughts and feedback!
