A coding agent, maturing fast
Pier is built by Alphabench: a coding agent made in India, for the world, that lives in your terminal.
A coding agent is mostly harness. The model is the engine, but the car is everything else: the editing tools, the system prompts, the loop that decides what to do next and feeds the last step into the next. Get that right and a cheap, home-grown model punches well above its price.
Pier is that harness, built to work with every serious model. Pick one yourself, from Sarvam and DeepSeek to GLM, Kimi, Qwen, and more, each billed at its API cost, or let Pier Hybrid, the intelligent router, classify each request and run it on the best-fit model. It reads your repository the way you would, plans with discipline, and keeps you in control at every step. See the kind of work people hand it on the use cases page, or what a finished job actually costs on cost per task.
And it is improving recursively: we build Pier with Pier Code, so every gain compounds into the next. This is not a finished product frozen in place. It is a rapidly maturing one, getting sharper with every release, as you can follow on the changelog. Pier is also open source, developed in the open on GitHub. All of it starts at five dollars a month.
Mostly harness
A coding agent is the engineering around the model: the tools, the prompts, the loop that turns a cheap token into reliable work. We make the harness punch far above its price.
Right model for the job
Pier Hybrid, our intelligent router, classifies each request by type and complexity and runs it on the best-fit model. Prefer to choose yourself? Every model from Sarvam and DeepSeek to GLM, Kimi, and Qwen is in the picker, billed at API cost. Or bring your own Sarvam or OpenRouter key and use Pier free.
Recursively self-improving
We build Pier with Pier. Every improvement to the agent compounds into the next, so the product matures faster than we could ship by hand.
Open source
Pier is open source and developed in the open on GitHub. Read the code, build it yourself, file issues, and send pull requests. How the agent works is not a black box.
