Telegraph REST API Client

Lightweight offline REST & GraphQL API client for VS Code

Visit Website
September 8, 2026 I built a lightweight offline REST & GraphQL client for VS Code

I wanted a simple API client inside VS Code without requiring an account, cloud sync, or a separate application. My motivation started when Thunder Client moved from free to paid plan, which made me look for a lightweight alternative. So, I build a much better alternative which will have features of both Thunderclient and Postman but not just that. I have added lots more than that and it sizes on about 250KB.

So I built Telegraph REST API Client — a free, open-source, fully offline REST and GraphQL client for VS Code.

It supports collections, environments, authentication, request history, SSE/NDJSON streaming, raw HTTP request inspection, and importing from Postman, OpenAPI, cURL, and more.

Open VSX: https://open-vsx.org/extension/riturajshakti/telegraph-rest-api-client

I'd love to hear what other developers think and what features you'd like to see.

    The trigger is clear, but have developers actually switched from Thunder Client/Postman to Telegraph, or are they mainly trying it because it’s free and offline?

      I am not sure about this, but one thing I can confirm that - In just one day I got 200 downloads on OpenVSX (I cant paste link here but you can search "Telegraph REST API Client" by riturajshakti in openvsx site)
      please try and tell me what do you think personally if its worth it and its better than thunder-client. Honestly I would love to hear honest feedback from you

        That 200-download start is interesting. I’d be curious to dig into what users actually choose Telegraph for. If you’re open to it, what’s the best email to reach you on?

I wanted a simple API client inside VS Code without requiring an account, cloud sync, or a separate application. Existing tools felt too heavy for my workflow or had limitations.
