HTTL Project, powered by GitHub Copilot’s agentic capabilities, analyzes your codebase, generates OpenAPI specs, and builds realistic payloads - all inside VS Code, no context switching needed.
I’m excited to share something I’ve been quietly building: HTTL Project, a VS Code extension that combines a new language (HTTL) with an AI agent built on GitHub Copilot to take your API development to a whole new level.
---
### 💡 What is HTTL Project?
It’s more than a code helper - it’s a smart assistant inside VS Code that can:
- 🔍Analyze your codebase - 📄 Auto-generate OpenAPI specifications - 🧠 Create realistic request payloads - ⚡ Execute and test endpoints - instantly
All of this happens in your editor, with zero configuration, using a clean, developer-friendly syntax powered by HTTL.
---
### 🤖 Why It’s Different
While Copilot usually helps line-by-line, this project explores something new: 👉 an agentic workflow - where Copilot helps carry out larger, goal-oriented tasks, like turning an entire project into a working OpenAPI spec.
This isn’t about autocomplete. This is about AI doing the boring stuff so you can stay in flow.
---
### 🚀 Why I Built It
I wanted something that:
- Doesn’t require switching between tools like Postman, Swagger, and YAML editors - Doesn’t rely on heavy annotations or custom formats - Uses AI in a practical, intelligent way, not just to fill in code
So I built HTTL Project - a small idea that’s becoming a powerful workflow.

If you’ve ever wanted Copilot to do more than just suggest code... This is your first taste of what’s coming next.
Try it out. Break it. Build with it. And let me know what you think - I’d love your feedback 🙌
designed for developers who prefer using code to interact with APIs rather than relying on a UI (yes, finally!).
That's literally how developers have always worked with APIs. They are literally programming interfaces, not graphical user interfaces.
Good to go tool for better coding experience and at same platform on real time basis without switching to any other app.
HTTL Project looks like a smart blend of innovation and practicality for API developers.

Who hunted HTTL Project?
HTTL Project was hunted by Eugene. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
