Create Applications from Natural Language. Ship Them with Deterministic Logic. Always in Control.
Connect Leapter to Claude or any other MCP and build internal tools from a description. The frontend is generated like any modern AI app builder. The business logic underneath sits in a Leapter Blueprint the domain experts can read, verify, and approve, before anything goes live.
Vibe-coding works. Until deterministic logic matters.
With Leapter, the UI gets generated the way it does anywhere else: fast, conversational, from a description. The difference is what happens beneath the surface. Instead of disappearing into JavaScript or Python, the business logic compiles into a Blueprint: a visual artifact the rule owner can read on one screen and approve before deployment.
Vibe-coding speed. Enterprise control. One workflow.
| AI app builder alone | AI app builder + Leapter | |
|---|---|---|
| Frontend | Generated from a description | Generated from a description |
| Business logic | Buried in JavaScript or Python | Visible Blueprint, approved before deploy |
| Who can verify it | A developer, sometimes | The domain expert who owns the rule |
| Change cycle | Re-prompt, re-test, hope | Edit the Blueprint, sign off, deploy |
| Audit trail | Output logs only | Intent, version, and execution linked |
| Enterprise-ready | For prototypes | For production |

The Leapter difference
Create applications using Claude
Use Claude Code to create the application. It generates the UI, while Leapter takes care of the logic underneath. All using natural language. No coding needed.
Get a visual representation of the decision logic behind it
The whole decision logic of the application can be viewed as a Leapter Blueprint – a visual representation of the logic.
Review, test and run the logic by accessing the Leapter Lab
Read the project as a structured document with diagrams in context, or zoom into a single rule. Every execution produces a complete record of which branches fired. Walk through any execution one step at a time and see exactly which branch fired and why. Test decision branches and edge cases, generated automatically. Every live execution is logged with full trace, re-runnable with one click.
Built for the people who own the decisions
Business Technologists & Low-Code Builders
Replace the legacy rules engine you’ve outgrown. Build and change decision logic yourself, in your own language, without a developer ticket for every rate change.
CIOs & Heads of AI
You’re being asked to deploy agents at scale without losing control. Leapter is the deterministic layer between LLM reasoning and consequential execution, so your agents stay fast, auditable, and inside policy.
Heads of Compliance & Risk
Accountable for every automated decision under the EU AI Act. Leapter gives you a visual audit trail your regulators can read, without waiting on engineering to explain what the model did.
Engineering Leaders
Stop writing business logic on behalf of the business. Let domain experts own what they own, and free your team to build the platform around it.
