⭐ If you find DevCraftKit useful, consider starring this repository to help more developers discover it.
Developers spend countless hours switching between different websites just to complete small everyday tasks.
One site for formatting JSON.
Another for decoding JWTs.
Another for subnet calculations.
Another for encoding text.
Another for sanitizing logs.
Each has a different interface, different privacy policy, different limitations, and different expectations about your data.
DevCraftKit exists to replace that scattered collection of bookmarks with one consistent, privacy-first toolkit designed specifically for developers.
Whether you're writing code, debugging production systems, configuring infrastructure, analyzing logs, troubleshooting networking issues, or sharing diagnostics with teammates, DevCraftKit provides browser-based utilities that are fast, simple, and trustworthy.
Browse the growing collection of developer utilities built for everyday workflows.

Paste application logs, server logs, API responses, security logs, or upload log files and automatically detect and mask sensitive information before sharing them with:
- AI assistants
- GitHub Issues
- Slack
- Discord
- Jira
- Support tickets
- Documentation
- Public forums
Everything happens entirely inside your browser.
The internet already has thousands of developer utilities.
Most solve one problem.
Many upload your data.
Many have inconsistent interfaces.
Many contain unnecessary distractions.
DevCraftKit follows a different philosophy.
Every tool should be:
- Fast
- Privacy-first
- Easy to use
- Consistent
- Reliable
- Focused on solving one task well
Instead of collecting random utilities, DevCraftKit aims to become the toolkit developers naturally keep open every day.
Privacy is not an afterthought.
It is the foundation of DevCraftKit.
Whenever technically possible, tools execute completely inside your browser.
That means:
✅ No uploads
✅ No accounts
✅ No server-side processing
✅ No waiting for remote computation
✅ No sensitive information leaving your device
Your browser performs the work.
Your data stays with you.
DevCraftKit is designed for anyone working with software and infrastructure.

Developers regularly share logs when asking for help.
Unfortunately, logs rarely contain only the error.
They often include:
- Customer email addresses
- Internal IP addresses
- API keys
- JWT tokens
- Passwords
- Session cookies
- Hostnames
- Internal domains
- Authentication headers
- Connection strings
- User IDs
- Trace IDs
- Credit card numbers
- Phone numbers
- Environment variables
Once shared, those values may end up:
- Inside AI conversations
- GitHub Issues
- Slack history
- Discord messages
- Public forums
- Support tickets
- Search indexes
Removing them manually is slow and error-prone.
Log Sanitizer automates the process.
Sensitive information including:
- API Keys
- JWT Tokens
- Authorization Headers
- Bearer Tokens
- Passwords
- Secrets
- Cookies
- Connection Strings
- Database URLs
- Environment Variables
- Emails
- Phone Numbers
- Credit Cards
- Identity Numbers
- IPv4 Addresses
- IPv6 Addresses
- MAC Addresses
- URLs
- Hostnames
- Domains
- File Paths
- Windows Paths
- Linux Paths
- User IDs
- Customer IDs
- Account IDs
- Request IDs
- Trace IDs
- Session IDs
- AWS Resource IDs
- Buckets
- Cloud Resources
- Kafka Topics
- Queues
- User-Agent Strings
…and many more.

Many online tools require you to upload your logs.
That means sensitive information reaches someone else's infrastructure before you even sanitize it.
DevCraftKit takes a different approach.
Whenever possible:
- Processing happens locally.
- Detection happens locally.
- Replacement happens locally.
- Downloads are generated locally.
Your browser performs the work.
Your data never has to leave the tab.
DevCraftKit is continuously expanding.
Current plan includes more than 30 browser-based developer utilities across:
- Security

…and many more.
Unlike many online utilities, DevCraftKit focuses on:
- Privacy
- Simplicity
- Performance
- Consistency
- Reliability
Every tool follows the same design philosophy so you spend less time learning interfaces and more time solving problems.
