Mainframe lives inside the OpenFinance app at openfinance.tech/mainframe. Each card is a template for a trading tool or a website. Pick one, check its demo, and click Deploy: OpenFinance builds the app for you in Chat and can ship it to your own GitHub and Vercel.
Mainframe page with the heading MainFrame: Build Tools and Apps, a Connectors card with Connect buttons for Vercel and GitHub, section tabs and the first row of template cards

What a template is

Every card in the gallery is made of two things:
  • A prompt. A long, precise brief that tells the builder exactly what to make: the layout, the data sources, the copy, the safety rules and a list of checks to run before calling the job done. You can read every prompt before you use it.
  • A demo. A preview of what the prompt produces. Website templates show a live page you can click around in. Trading tools show a screen captured with live data, so the gallery never needs your key.
When you click Deploy, the prompt goes into Build mode as your first message. The result is a fresh copy of the app that belongs to you: code you can push to your own GitHub repository and a site you can deploy to your own Vercel account. Nothing is shared with other people who use the same template. Tabs above the grid filter the cards. A search box beside them matches template names, sections, descriptions, tech stacks and tags.
Tabs reading All, Prediction Markets, Perp Dexes, Trading, Websites and Animated, with a search box reading Search templates, stacks or tags

Section tabs and search

Each tab holds one kind of template: Each card shows the demo, the title, a one-line description, tags, the output (for example “Next.js app” or “Single index.html”) and the prompt’s length. Hover a card for three buttons: Prompt, Open demo and Deploy. The Mainframe card also has a Live link to a deployed copy.

Every template

Here is every template in the gallery today, grouped the same way as the tabs. Click a card to read its own page. The gallery grows over time, so the app may show cards that are not listed here yet.

Before you start

A few things are worth knowing before your first deploy.
  • Browsing, opening demos and reading prompts work without an account. Deploying asks you to sign in. Please make an account at openfinance.tech to get your keys.
  • Connect GitHub and Vercel once, in the Connectors card at the top of the page, so the finished app can ship straight from the chat.
  • Templates are long prompts, so a build spends more AI credits than a short chat. See Models and AI credits.
  • Trading templates place real orders only with your own OpenFinance key, pasted in your own copy. Read Keys and safety first.
