Leap - Full-stack dev AI that works with you, not instead of you

Hey PH,

We built Leap after trying every other AI app builder and hitting the same walls: limited to single-page apps, locked into specific BaaS platforms, and no support for production workflows.

These tools also lack proper isolated test environments, which limits control over deployment. Approving a buggy SQL migration, for example, could impact your production database.

That works for some use cases, but as developers, we wanted support for more advanced infrastructure and architectures.

These may not be flaws. The tools seem designed for non-developers who prioritize simplicity and may not need advanced features. But we wanted something different.

A tool built for developers who want the speed of AI without giving up control of their architecture, APIs, infrastructure, or deployment.

So what makes Leap different?

You still start from a prompt, but after that, the workflow is developer-first:

- You can iterate using versions and diffs.
- Apps use Encore.ts for the backend. It's our open-source framework, trusted by thousands and with 10k GitHub stars (https://github.com/encoredev/encore).
- It generates live architecture diagrams and API documentation, so you understand what you're building even when much of it is generated by AI.
- Manual code edits are of course supported.
- The framework includes a declarative infrastructure layer, like a cloud-agnostic version of AWS CDK, enabling Leap to set up infra for microservices, databases, pub/sub, and more in about 1–2 seconds.
- The preview environment you work in is completely isolated from prod.
- For deployment, you can use open-source tools to package the app into Docker containers and deploy anywhere.
- Or use Encore Cloud to manage deployments and infra provisioning in your AWS or GCP cloud.

Leap isn't meant to replace every workflow or tool right away. We expect it to be most useful for spinning up new projects or building isolated systems within an existing product.

We built Leap because nothing else met our needs as developers. Now that we're starting to welcome users, I'd love to hear your thoughts:

- Does this solve any development or deployment pain you've experienced?
- What would you need to confidently use this to build production-grade apps?
Your feedback will help shape Leap!

looks and sounds great!

Guys... this is incredible. Just tested it out and I'm in love. One of my favorite stacks outside of Django. Let me know how I can help spread the word. I don't think enough people know about Encore yet, but it's incredibly undervalued.

Hi Marcus, I hope you're doing well!

I've been using the Leap platform and I'm really impressed with its concept and the potential it offers for building AI-powered workflows and automations.

I’d like to ask if there are any plans in the Leap roadmap to add native features for generating images or animations using AI, directly within the platform. This would be a valuable addition for projects that require visual or interactive content inside the workflows.

Thanks in advance for your attention, and congratulations on the amazing work with Leap!

Best regards,

I love it. Better than most

There’s no comparison with any other code agent — generating the entire infrastructure and hosting it in your own cloud within minutes is just insane.

Under the hood, what services of AWS/GCP are you using for the deployment of the apps?
