Built for the agentic age

Built for screens. Now built for agents.

Yesterday's trading software was made for people clicking through screens. Today's pioneers build with AI agents, so your agent builds the tool you need in minutes instead of you waiting in a vendor's queue, on infrastructure it can work with and you control.

If you trade

You don't need to build the whole system, just the piece your workflow is missing: a panel, a check, a report. Describe it, your AI agent builds it on your own Open Meridian, and you use it minutes later.

Run it free

If you code

Skip the glue code. Write your bots, analytics and plugins in Python on one data model of accounts, positions and instruments, and each save is live in about a second.

Build your first plugin

  • Safe by construction. A tool can touch only what it was granted.
  • Yours to keep. What you build, alone or with AI, is your code and your IP.

How it works

Running in 30 minutes

  1. 1

    Install

    macOS or Linux

    curl -fsSL https://open-meridian.com/install | sh

    Windows

    Install WSL 2 with Ubuntu (wsl --install in PowerShell), then run the same command inside Ubuntu.

    wsl --install

    Windows through WSL 2 isn't tested yet: tell us how it goes.

  2. 2

    Point your AI agent to the repo and describe your big idea

    Your agent brings your deployment up and builds the plugin from the template, live.

  3. 3

    Test, iterate, release

    Check it with meridian plugin check, change it until it's right, then release it to your deployment.

Proof

Don't take our word for it. Read it.

Everything below is true today, and you can check it yourself.

Open source

The runtime, the command line and the plugin kit are public. Read every line.

Half an hour

From nothing to a running deployment on a laptop, following the setup guide.

Ready for AI agents

Every new plugin comes with the instructions a coding agent follows to build it and change it live on your deployment.

Your data, your control

Your orders, positions and keys stay in your own environment, and you decide who, and which tools, can touch them. See the stack.

Shape what comes next

Missing something? Ask in the open, not a vendor's queue.

Request it on GitHub, where every request gets an answer, or book a call; whatever we build goes into the open platform, so share only what you're happy to see public.

Own it. Build on it.
