Free code secret scanner for developers
Check code snippets for API keys, tokens, connection strings, private URLs, and other sensitive values before sharing them in tools, tickets, email, or chat.
Check snippets before code is shared
Code Secret Scanner is a free developer utility for quickly reviewing snippets before they are pasted into AI tools, issue trackers, email threads, chat rooms, or documentation. It helps flag sensitive-looking values so developers can remove or replace them before sharing.
API keys
Patterns that look like service credentials or generated access keys.
Tokens
Bearer tokens, auth tokens, and other high-entropy values.
Connection strings
Database and service connection details that may expose usernames, hosts, or passwords.
Private URLs
Internal URLs and endpoints that may reveal private infrastructure details.
Emails and server names
Contact addresses, hostnames, and server identifiers that may not belong in shared snippets.
Suspicious secrets
Database names, sensitive labels, and values that deserve manual review before sharing.
Before using AI tools
Review snippets before pasting code into AI assistants or automation tools.
Before sharing tickets
Check examples before adding them to issue trackers or support tickets.
Before sending snippets
Scan code before sending it by email, posting it in chats, or adding it to documentation.
Review code intentionally before sharing
The scanner is intended as a pre-sharing review step. Treat any result as a prompt for human review, remove sensitive values before sending code elsewhere, and avoid pasting production secrets into any tool unless your organization has approved that workflow.
