On June 14 we’ll wind down the Tempo web editor and move everything to the desktop app. Until then, keep using it at app.tempo.build — your prompt credits work in the new app too, and we’re doubling available credits during the migration.
Our new local desktop app is a significant rebuild of Tempo from the ground-up — faster, more feature-complete, and far more powerful. Why are we making the change? Short answer: we couldn’t fully build Tempo using Tempo (meta, I know). Our own engineers were gravitating back to tools like Cursor ~70% of the time, and we only wanted to sell a product we use ourselves. The new app fixes that — the whole team is now on it 8+ hours a day, every day. We love it and hope you will too. The new app brings with it a few key changes:
  1. Local — run your code on your machine. Better performance, code privacy, and security.
  2. Frontier agents — handle tasks of any size and complexity, with tokens direct from Anthropic / OpenAI / OpenCode.
  3. Git Worktrees — run chats across multiple copies of your codebase in parallel so you can work on multiple features at once.
Watch the quick intro below, then follow the steps to get set up.
Here’s how you get started:
1

Install the Tempo desktop client

Download from tempo.new and sign in with your existing account.
You’ll need Node.js and Git installed on your machine. Tempo will alert you if either is missing.
2

Add your project

Click + Add Project, paste your repo’s git clone URL, or pick a local folder with a copy of your codebase checked-out.
If you haven’t already please commit then push your project to git from the git tab.

Connect your AI account

The new app gives you the choice of three coding agents — each works with different subscriptions.

Paying for Tempo on the web app? Your subscription and any unused prompt credits carry over automatically. Learn More
  1. Click the Terminal tab at the bottom of any workspace (some layouts call it CLI).
  2. Type claude /login and press Enter.
Prefer an API key? Choose “Use an API key” at the browser prompt and paste one from console.anthropic.com.
  1. Click the Terminal tab at the bottom of any workspace.
  2. Type codex login and press Enter.
Prefer an API key? Pick “Use an API key” at the prompt and paste one from platform.openai.com/api-keys.
  1. Click the Terminal tab at the bottom of any workspace.
  2. Type opencode login and press Enter, then follow the on-screen prompts.
OpenCode accepts API keys from Anthropic, OpenAI, and other supported providers.
No sign-in needed. Open the Chat tab, pick any model from the dropdown at the bottom, and start chatting — your Tempo plan covers it. Learn More
For users on base plans (<$100), it is strongly recommended to use Sonnet/GPT-5.4 on low effort as Opus/GPT-5.5 on high effort burn credits extremely fast.

Start building!

🎉 You’re all set. Open the Chat tab and start prompting.To see a live preview, just ask the AI to:
  • Configure a run script, then click Play in the top bar — or edit tempo.config.json yourself (reference).
  • Create a canvas for a Figma-style design surface — or right-click the Canvas tab → New Storyboard.

​
Once you’re in — 3 quick tips

A short follow-up walkthrough covering the most common things to set up after install:
  1. Add a run script. Configure one in tempo.config.json (or ask the AI to do it), then hit Play to see your live preview. Reference
  2. Set your environment variables. Anything your app reads from .env lives in the project’s env panel — don’t forget API keys, DB URLs, etc.
  3. Generate a canvas with storyboards. Ask the AI to create a canvas, or use “Route” storyboards to map full pages. Heads up: the chat now lives on the right inside the canvas tab.
Still stuck after that? It’s almost always a git or AI authentication issue — DM me and I’ll get you unblocked.

What happens after June 14

On June 14 we’ll wind down the Tempo web editor and move everything to the desktop app. Until then keep using it at app.tempo.build — your prompt credits work in the new app too, and we’re doubling available credits during the migration (Learn more). A few things to know:
  • Your plan comes with you. Subscriptions and remaining credits carry over automatically, and you can manage billing right inside the desktop app under Settings → Plan. app.tempo.build will also stay up as a read-only billing portal if you ever need it. Learn more.
  • As long as your project is on GitHub, you’re set. Push from the web app’s git tab and you can clone it into the desktop app in seconds. Prefer a local copy? Hit Download ZIP on any project. If you’d rather we handle it, email support@tempo.new — we’ll retain old repos for 60 days after June 14 and can export them for you on request.
