Mistle

Open source background agents

[Jonathan Low @jonathanlowhy]

@thomasjiangcy and I have been working on building a platform for running sandboxed coding agents.

Mistle is our open source take on Ramp Inspect and Stripe Minions.

Mistle’s sandboxes are designed to be credential-less. Credentials stay outside the sandbox and are injected through a proxy at request time.

You can test this locally on a single node with Docker.

Issues, questions, and feedback welcome: https://t.co/sr9gnKfCPx

[Thomas Jiang @thomasjiangcy]

we're back - launching @mistledev today 🫰

you can:
- Ask Your Codebase: Explore features, trace bugs or plan next steps.
- Ask In Chat: Highlight any response to get it explained in plain English.
- Review: Run a review to check AI’s work. Catch out logic and quality issues with recommended fixes.

Relaunching Zapi as @mistledev

Mistle is Cursor for non-technical builders.

We built Mistle to help non-technical folks learn better as they build.

Give it a try at https://t.co/kFAseCkek3

[Mistle @mistledev]

We're launching Zapi as an AI Copilot for Product Teams. With Zapi - Write and turn PRDs into prototypes in minutes.

How it works:
1. Prompt your idea.
2. Iterate till you get a working PRD
3. Zapi builds a hi-fi prototype according to your specs
4. Publish and share

[Mistle @mistledev]

🧭 Navigation just got an upgrade in Zapi!

We started with 1 view mode—Preview. Then came more features, and a dropdown to switch modes.

Now with 7 modes, we’ve moved to a sidebar so you can see everything at a glance.

Better UX, better overview. ✨

[Mistle @mistledev]

Beta testers wanted!

Join in 2 easy steps:
1. Join discord: https://t.co/cEj3saIA9h
2. Post in #general channel with your Zapi user id

[Mistle @mistledev]

🎉 Hot off the press: Specifications Mode 🚀

Each Zapi project now begins with a Specifications Doc that steers the AI in building exactly what you need.

Edit the spec directly or prompt Zapi to broaden or narrow the scope.

When you're ready, go into implementation!

[Mistle @mistledev]

Secrets Management is live in Zapi!

- Build integrations safely without exposing sensitive configurations to AI or in the codebase
- Use a separate set of secrets for preview vs live environments

[Mistle @mistledev]

We’ve introduced a Markdown Editor to make it easier to manage content for your sites on Zapi. To edit content, go to Content View > Select a collection > Select a content.

[Jonathan Low @jonathanlowhy]

Just launched the ability to build backend capabilities in Zapi! For now, it works great with building forms and waitlists. We're going to be tuning this further over the next couple of weeks so that people can build apps.

Give it a try and let me know your feedback.

Editing SEO through a chat interface sucks. So we're introducing Content View mode - to make it easy to preview and edit SEO directly on @HeyZapi

[Mistle @mistledev]

We just rolled out improvements to the Select Tool. Click the "Select Pointer" in the chat input and select an element in the Preview to tell AI what to focus on.

[Mistle @mistledev]

Just launched - Instant Preview!

Preview Mode now updates in real-time as the site's code changes. We made a huge infra change to provide every user with dedicated servers so that you can get feedback instantly.

Here's a demo of Instant Preview + Version History

[Mistle @mistledev]

Just released in Zapi: Manage images with the Assets View Panel
- We've made it easier to upload and manage assets to better support content rich websites!
- Upload your assets and drag them into the Chat Interface to get AI to use them in your site or to reference them.

[Jonathan Low @jonathanlowhy]

Change History just went live! On @HeyZapi, you can now restore previous versions of your site. So feel free to be more explorative with changes and backtrack when you need to!
