Superhuman improvements to your agent prompts and context.

Bitfab is a coding agent plugin that creates datasets from your trace data and experiments against them for superhuman improvements.

Two skills backed by our infrastructure to improve your agent prompts, context, and tools without leaving your coding agent.

/bitfab:setup

Precision instrumentation of the Bitfab SDK for tracing and replay scripts.

/bitfab:improve

Curates a dataset of traces with your guidance, labels the data, runs experiments, and lands the fix.

Improving software that uses LLMs without a dataset leads to endless cycling. You fix one case and break ten others. Building good datasets and experimenting against them manually takes too long.

We're making iterating fast and reliable by turning your coding agent into a data wrangler and mad scientist. No heavy dashboards, no brittle evals.

Just two coding agent skills backed by our infrastructure packaged into a plugin.

We've been building LLM products for three years. Cycling on prompts, tools, and context has cost us months. Bitfab is what we wish existed.
