I’ve been building a collection of free dev tools and APIs as a hobby project — things like JSON formatting, hash generation, QR codes, UUID generation, SSL checking, and uptime monitoring.

Everything runs on a single VPS and is completely free to use (no accounts needed, no rate limits currently). I’m looking for a few people who’d be willing to:

• Try the tools and tell me what’s broken or missing
• Suggest features based on what you actually need day-to-day
• Give honest feedback on whether this is useful or just reinventing the wheel

In exchange, I’m happy to:

• Add any tool/API endpoint you’d find useful
• Set up custom monitoring for your services
• Help with any self-hosting questions (I’ve been doing this for a while)

This isn’t a product launch or a sales pitch — I genuinely want to make these tools better and could use some real users to tell me what matters.

If you’re interested, comment here or DM me. Happy to share the link privately (don’t want this to come across as self-promotion).

What the toolkit currently includes:

• JSON/YAML formatter and validator
• Hash generator (MD5, SHA-1, SHA-256)
• QR code generator
• UUID generator
• SSL certificate checker
• HTTP status code reference
• Base64 encoder/decoder
• URL encoder/decoder
• Uptime monitoring API
