100 micro-tools in 100 days — all powered by Cloudflare Workers.
We're building a collection of fast, free, and focused developer tools that run at the edge. Each tool solves one problem really well, and you can learn how it works under the hood.
WorkersCanDo is more than just a tool collection — it's a learning journey. We're exploring what's possible with Cloudflare Workers by building real, useful tools and sharing everything along the way.
Whether you're curious about edge computing, want to learn serverless development, or just need a quick tool that works — you're in the right place.
100 tools. 100 days. Zero excuses.
Every tool we build is:
- ⚡ Fast — deployed globally on 300+ edge locations
- 🎯 Focused — does one thing and does it well
- 🆓 Free — no auth, no limits, just use it
- 📖 Open — learn from the code, contribute your ideas
Here are some tools already live and ready to use:
| Tool | What it does |
|---|---|
| URL Metadata API | Extract title, description, OG tags from any URL |
| Dynamic OG Images | Generate social sharing images on the fly |
| ...and more coming every day |

This project is perfect if you want to:
- Learn Cloudflare Workers — see real examples of what's possible
- Understand edge computing — why it's fast and when to use it
- Build your own tools — use our code as a starting point
- Contribute ideas — suggest tools you wish existed
Have an idea for a micro-tool? We'd love to hear it! Great suggestions are:
- Small and focused (one clear purpose)
- Useful for developers or everyday users
- Possible to build with Cloudflare Workers
Want to build a tool yourself? Even better! Check our docs for guidelines on how to contribute.
Star this repo to follow along as we build all 100 tools. We share what we learn, including the mistakes.

Beginner: Cloudflare Workers let you run your code on servers all around the world, so your site and APIs are super fast for everyone. You don’t need to manage any servers—just write your code and deploy. It’s perfect for building tools, APIs, and microservices that need to be fast and reliable.
Expert: Cloudflare Workers are serverless functions running at Cloudflare’s edge network (300+ locations). They enable ultra-low-latency APIs, microservices, and dynamic content, with instant cold starts and global scaling. Workers are ideal for edge-first architectures, JAMstack, and modern web apps that demand performance and resilience.
We're proving that you can build genuinely useful tools with Workers, and we want to show you how.
