Screenshots of code, API dashboards, and terminal output go viral on X every day. StreamBlur makes sure your API keys and tokens don't go viral with them.
Secrets are blurred before you take the screenshot. Zero editing required.
Add the Chrome extension once. No configuration needed - it starts protecting immediately.
Work in your API dashboards, code editors, and terminals. Secrets get blurred in real-time.
Take a screenshot and post to X. Secrets are already masked - no editing, no risk.
From build-in-public updates to debugging threads, StreamBlur has you covered.
Sharing a snippet from your editor or terminal? StreamBlur masks API keys, database URIs, and tokens before you screenshot.
Showing off your Stripe revenue, OpenAI usage, or AWS setup? Dashboard keys and tokens stay hidden.
Recording a quick demo or tutorial clip for X? StreamBlur protects in real-time, so every frame is safe to post.
Posting progress updates on your SaaS or side project? Show the wins without exposing your production credentials.
Posting a "anyone seen this error?" thread with logs? StreamBlur catches secrets hidden in stack traces and error output.
Celebrating a deployment? Showing deployment dashboards and CI/CD pipelines without leaking environment variables.

Screenshots on X reach thousands of people in minutes. Bots scrape for leaked keys in real-time.
StreamBlur works at the browser level - it blurs secrets in the actual page content. Any screenshot tool (browser built-in, OS screenshot, Snipping Tool, ShareX, etc.) will capture the already-blurred content. The blur happens before the screenshot, not after.
Yes! Since StreamBlur operates in real-time on the page, screen recordings (OBS, Loom, native screen recorder) capture the blurred version. Perfect for quick demo clips on X.
StreamBlur prevents future leaks - it can't retroactively blur an already-posted image. If you've leaked a key, rotate it immediately in your provider's dashboard. Then install StreamBlur to make sure it doesn't happen again.
StreamBlur scans all browser content for secret patterns. If someone posts a raw API key in a tweet, StreamBlur would blur it on your screen. But the main value is protecting your own dashboards and code before you screenshot them for posting.
Yes. Toggle Stream Mode off with Alt+Shift+S to temporarily reveal all values. Just make sure you toggle it back on before taking any screenshots!
