Stop the "Fix ➔ Fail ➔ Retry" Loop
Inject runtime context to fix bugs now — before the loop burns through your time and credits.
The IDE Extension for AI One-Shot Bug Fixing
Powered by real runtime traces, variables, and logs — not guesses.
Works seamlessly with your stack
See real runtime values directly in your code
Syncause captures traces, function arguments, and logs as your app runs, then replays the exact runtime values inline with your source code.
Don't reproduce. Just replay.
When a bug happens, you already have the truth.
Always On
We record execution flow in the background. Zero config.
Bug Happens
Crash, error, or logic fail? No need to restart or add logs.
Inject Truth
Feed the snapshot to coding agents. It fixes the bug instantly.

Frequently Asked Questions
Absolutely. Syncause is built to complement Cursor/VS Code. While AI Agents try to add logs and restart your app, Syncause instantly feeds runtime data to Cursor/VS Code without breaking your flow.
Syncause is designed for local development (Dev/Test environments). It automatically detects production builds and becomes inert to ensure zero performance impact on your live users.
