SecureLint identifies API keys and secrets from 80+ providers in real time. The moment a secret appears on a page — in a form, AI prompt, or web app — SecureLint masks it before it can be seen, screenshot, or shared.
Add to Chrome — FreeAPI keys are the crown jewels of any development environment. A single exposed AWS key can drain your cloud account. A leaked Stripe key can trigger fraudulent charges. A compromised OpenAI key can result in thousands of dollars in unexpected API bills.
The most common causes aren't sophisticated attacks — they're human error: pasting a key into the wrong browser tab, accidentally sharing a screen during a meeting, typing credentials into an AI chat window, or copying a secret into a public Notion doc.
SecureLint catches these moments before they become incidents. It monitors your browser activity for API key patterns and masks them the instant they're detected.
SecureLint ships with detection signatures for the most common cloud providers, SaaS platforms, and developer tools.

Developers routinely paste API keys into ChatGPT, Claude, or Gemini to debug integrations. SecureLint intercepts and masks them before they reach the AI's context window.
During code reviews or demos, secrets visible on screen can be captured by attendees. SecureLint masks them in real time so they're never visible.
Copied API keys can be accidentally pasted into the wrong application. SecureLint's clipboard monitoring detects secret patterns at paste time.
Cloud dashboards, CI/CD tools, and admin panels often display API keys. SecureLint masks them site-wide so they're protected even in your own tools.
Secrets pasted into Notion, Google Docs, or Confluence are masked, preventing public sharing or link exposure.
API keys logged to the console or visible in network requests are masked to prevent shoulder surfing and recording.
API key masking is the process of automatically detecting and hiding API keys, tokens, and credentials so they cannot be accidentally read, screenshot, or shared. SecureLint replaces detected secrets with ••••••••• characters in real time.
Yes. SecureLint Pro allows you to define custom regex patterns for internal tokens or proprietary credential formats specific to your organization.
Yes. SecureLint monitors all browser text inputs, including AI chat interfaces. If you type or paste an API key into ChatGPT, Claude, or any other AI assistant, SecureLint will detect and mask it.
No. SecureLint only masks the visual display of secrets. The underlying data is unchanged and the page continues to function normally. You can toggle masking on and off via the extension popup.
SecureLint ships with 100+ detection signatures covering 80+ providers, including AWS, GCP, Azure, OpenAI, Stripe, GitHub, Twilio, SendGrid, Heroku, Slack, and many more. The library is regularly updated with new providers.
