Firebender 0.9.14 for android engineering is out now:

- Agent changes are check pointed! So if you don't like a change, easily revert back to a previous point
- Ability to quickly @ mention any file
- Polished markdown rendering and typing experience

Firebender 0.9.13 is out with two major agent updates:
- Websearch
- Auto terminal command running

Firebender created a web search tool for itself in one shot in one of the most disgusting codebases in existence 😅

have a feeling we're going to start seeing this on all our hackernews posts lmao

Oh hell yes! Been looking for something like this for my KMP/CMP stuff! (and Jetbrains are dragging their feet with Junie)

First impressions after about an hour of using it.

1. Absolutely love how it fixes it's own errors. 😂
2. Autocomplete feels much faster than Copilot.
3. Very eager to make changes outside of the scope of the file I'm working on. Might be user error and might be fixable with rules

4. Sometimes it feels like it's doing things under the Hood, but I don't get an indication about it until the code in my open file changes. So not sure if it's working or hangs.
5. Multiplatform just works.

This is basically cursor for Android Studio/IDEA.

Similar UX and even keymaps. You can use your own API keys (although you can use a lot of models for free??) and even supports local LLMs. Has an `agent` mode too!

YC backed, and free (for now at least). Looks promising!

Future of Android Development will be multi-agents that code, fix bugs, implement UI changes from figma all autonomously. Firebender 0.9.6 proves this, and here’s why:

first blue sky post :)
