Start with a template

The leading OpenWeight harness for SaaS builders.

Neander keeps product intent, architecture, code, data, and infrastructure connected, so the first version becomes the foundation, not a throwaway reference.

01 Shape the product together
02 Build on sound foundations
03 Bring Your Keys & Subscriptions
Multiplayer collaboration Turn a customer need, workflow, or feature idea into something the whole team can inspect and refine.
Robust building blocks Use proven architecture patterns, reusable SaaS building blocks, and the context of your existing systems.
Integrated with Essentials Powered by GitHub, OpenRouter, Claude, and OpenAI. One connected workspace for your code and AI, from the first idea to the next change.

An IDE that helps everyone build

Neander translates intent into product decisions and working software, explaining what matters along the way so every contributor can participate from their own expertise.

01 Speak in product, not code Describe the business, the workflow, and the problems you’re solving, with no specification or technical vocabulary needed.
02 Asks only what changes the product Focused questions surface missing requirements and technical trade-offs before they become expensive rework.
03 Makes assumptions visible See the assumptions, recommendations, and architectural choices behind every proposed change. Neander recommends proven patterns and reusable building blocks.
04 Explains downstream impact See which screens, flows, data, and tasks a decision will change before it is applied.
05 Keeps you in control Neander can recommend and implement, while your team controls the direction, trade-offs, and final release.

From prototype to production,
without starting over.
