Built a coding assistant you can text - get back a Vercel preview link

Working on multiple projects, I’d get feedback at all times of the day, or just find tiny nits that annoyed me. I had to wait till I got home to make fixes.

To get around this, I built an app to make changes directly from Telegram. I didn’t want to shell out 1k on a Mac mini and set up OpenClaw, so I built my own infra. It right sizes the machine and selects the right model based on the complexity of the change/the context repo, and makes the change. Once the change is done, it sends me a text via Telegram with a preview link on Vercel. I can continue iterating by simply responding to the message. Once I approve the change, it automatically creates a PR ready for me to approve on git.

All in all, now I ship fixes from wherever I am and without walking around with my half open MacBook waiting for my Claude session to complete. I’ve shipped 50+ PRs myself on text in the last couple weeks while I actually feel happier touching grass.

Would love to get more feedback so that I can continue improving - https://patchydev.com

Can you tell us more about how you built this? Is it open source?

Built it with Next.js on the frontend, with a backend that provisions ephemeral machines to run the code changes. It uses the Anthropic API for the model layer and integrates directly with GitHub and Vercel’s APIs for deployments and PRs. The Telegram bot handles the conversation layer.

One thing I spent a lot of time on was dynamically right-sizing the compute and selecting the right model based on repo context and change complexity, so that simple fixes don’t spin up more than they need to.

Not currently open source.
