What is Firebender?

Firebender is an Android Studio plugin that writes Kotlin and Compose features, tests them in the emulator, reads Compose previews and fixes issues automatically. It adds Figma to code conversion, custom agents and parallel sub-agents, with SOC 2 Type II and ISO 27001 certification.

Firebender is a coding agent built specifically for Android development, delivered as a plugin for Android Studio. Rather than bolting general-purpose AI onto a mobile codebase, it leans on the IDE's own refactoring tools, debugger and logcat so that generated code is checked against the real build rather than assumed to work. The agent writes features, runs them in the emulator, inspects the result and iterates on its own output until the screen behaves as intended. The Figma to code path is the clearest illustration of how it works in practice. A designer link is pasted into the prompt, and the agent produces Jetpack Compose that follows the project's existing design system and components. From there it renders Compose previews, reads what the preview actually shows, and revises the layout across several passes. The same loop applies to ordinary feature work, tests and bug fixing, because the agent can open the emulator and observe runtime behaviour instead of only reading source files. Teams can shape the agent around their own conventions. Agent files define system prompts, permitted tools and workflows, and separate rule, slash command and skill mechanisms cover coding standards and repeatable chores. A Heavy mode fan-outs work to parallel sub-agents, keeping the parent context intact so large mechanical changes stay coherent. Selection-based inline rewriting and a voice mode round out the interaction options. It is aimed at Android engineers and platform teams rather than generalist developers, and the customer roster reads accordingly. The case for it against editors like Cursor or Windsurf rests on depth of IDE and emulator integration in one stack. Model choice is open, with several frontier models listed plus a bring-your-own-key route.

How do you use Firebender?

  1. 1Install the plugin from JetBrains Marketplace
    Download Firebender from the JetBrains Marketplace listing and install it into Android Studio. The agent runs inside the IDE, so no separate app is needed.
  2. 2Open your Android project and prompt the agent
    Work from a normal Gradle project. Describe the feature in the prompt box, add relevant files as context, and let the agent plan, search and edit.
  3. 3Convert a Figma frame to Compose
    Paste a Figma link into the prompt. The agent writes Jetpack Compose against your existing design system, then checks Compose preview renders and revises the layout over several passes.
  4. 4Define rules and a custom agent
    Add an agent.md file to set the system prompt, tools and workflow for a specialist such as a Compose UI expert. Rules, slash commands and skills capture standards and common tasks.
  5. 5Review how other Android teams adopted it
    Read the Instacart case study on custom rules to see how one engineering team configured the agent for its codebase.

  6. 6Scale up with Heavy mode
    For wide changes, switch to Heavy mode so sub-agents parallelize the work while the parent agent keeps context. The Tinder case study covers this workflow.

Pros and cons

Pros

  • Built specifically for Android Studio, using the IDE debugger, logcat and refactor toolsAI
  • Agent inspects emulator output and Compose previews, then iterates instead of guessingAI
  • Figma links convert to Jetpack Compose that follows the project's design systemAI
  • Custom agents, rules, slash commands and Heavy mode sub-agents allow team-level tuningAI
  • Model choice is flexible, including a bring-your-own-API-key optionAI

Cons

  • Only useful for Android work: no support for iOS, backend or web codebasesAI
  • Requires the JetBrains plugin and a local Android toolchain, so it is not a browser toolAI
  • Heavy mode and parallel sub-agents can be hard to audit on large, unfamiliar codebasesAI
  • Homepage shows no pricing tiers, trial terms or plan limits to compare before adoptingAI
