Developer leak checker

Check developer screenshots
for leaked secrets

Upload a developer screenshot, detect exposed API keys, tokens, .env variables, database URLs, and client info locally, then export a safe PNG.

No account. No uploads. Everything stays in your browser.

Features

Everything you need,
nothing you don't

Dev Leak Detection

Finds API keys, bearer tokens, GitHub tokens, database URLs, .env variables, webhook URLs, IPs, and emails.

Solid Redaction First

Uses permanent solid boxes instead of blur. The exported image is a newly rendered PNG with redacted data fully removed.

Fresh PNG Export

Download a clean, flattened PNG. Redacted areas are re-rendered into the export instead of being blurred on top.

Local OCR

OCR and detection run in your browser. No screenshot upload, no cloud processing, and no saved history.

No Account Required

No signup, no login, no tracking. Open the tool, scan your screenshot, export the safe version. That simple.

Risk Score

Get a developer leak score grouped by critical, high, medium, and low risks before you post.

Privacy proof

Built to keep screenshots
on your device.

LeakShot keeps the leak scan and redaction flow in the browser, then exports a newly rendered file.

OCR runs on-device

The developer screenshot is read and scanned inside the browser session.

No image upload

LeakShot does not send your screenshot to an app server for processing.

No account or history

There is no login, saved gallery, dashboard, or cloud history.

Fresh PNG export

Exported images are re-rendered as a fresh PNG, so original hidden image data is not preserved.

LeakShot can miss sensitive information. Always review the image manually before posting, especially terminal output, browser tabs, account names, file paths, logs, and secrets split across multiple lines.

How it works

Four steps before
posting screenshots

01

Upload or paste

Drop a code, terminal, dashboard, log, or .env screenshot. Everything stays in your browser.

02

Scan and detect

Local OCR extracts text and the dev leak engine flags keys, tokens, database URLs, webhooks, IPs, and emails.

03

Review & redact

See a risk score grouped by severity. Approve detections, adjust boxes, add your own, and choose a redaction style.

04

Export safe image

Download a clean, fresh PNG with selected leaks covered before posting publicly.

Best for launch

For creators, freelancers,
and developers.

LeakShot is focused on people who post proof publicly: client chats, payment proof, dashboards, error logs, analytics, invoices, and AI conversations.

Creators

  • Publish client wins without exposing emails
  • Share testimonials without private names
  • Post AI chats without leaking prompts

Freelancers

  • Share payment proof without account details
  • Post client chats without phone numbers
  • Show invoices without order or tax IDs

Developers

  • Share dashboards without API keys
  • Post error logs without tokens
  • Capture Stripe or analytics screens safely

Stop leaking API keys
in public screenshots

Free, local, and built for developers. Your screenshots never leave your browser.
