Your code. Your models. Your machine
A zero-cloud AI IDE that can investigate, plan, edit, validate, and repair—using the models and API keys you choose.
The AI-native code editor that gets it exactly right. No approximation. No bloat. Just perfect code, every time.
//
Zero cloud. Full control.
Your code stays yours. Your keys, your models.
Zero-cloud BYOK, by design
Your code and prompts go directly from your Mac to the provider you choose. Numar never proxies or stores them.

Local continuity, under your control.
Keep Pro conversations local to each project. Search when you need it, and choose how long they stay.

Memory & preferences
Approve what Numar remembers, then review, mute, or remove it anytime—globally or per project.
Local history
New Pro conversations are stored in a local database. You decide whether Numar may search them—recording always stays local.

Choose the right workflow—and model—for the task.
Standard keeps work moving in one inspect, edit, and validate loop. Pro adds phased work with deliberate planning and model choice for each stage.
Cross-Stack Agents
Coordinate focused work across local Numar workspaces while each workspace keeps its full context private.

Use cases
One tool. Every use case.
Full-stack development
From React components to database queries, Numar understands your entire stack. Edit across frontend and backend in one run — with full context of how the pieces connect.
Debugging and refactoring
Describe the bug or the goal. Numar reads the relevant files, traces the issue, and makes targeted changes — without touching code it doesn't need to.
Numar Test
After every edit, Numar finds the related tests, runs them, reads the failures, and fixes them — automatically. Ship with confidence, not just intention.
Numar Wiki
Numar reads your entire codebase and builds a structured knowledge base — module by module. When your code changes, it syncs only what's affected. Your project, always documented.

Benefits
Think deeper. Ship faster.
Agent Workflows
Use Standard for a continuous agent loop, or Pro Phased for explicit THINKING, PLAN, GENERATE, APPLY, and validation stages.
Zero-cloud BYOK
Your prompts and code go from your machine to the provider you configure. Numar does not receive or store them.
Local Memory & History
Keep approved preferences and new Pro conversations locally. Search past context and control retention per project.
Cross-Stack Agents
Ask questions and coordinate tasks across local Numar workspaces while keeping each workspace’s context isolated.
Numar Test
Run configured diagnostics and tests after code changes. Failures can return to the agent for repair.
Numar Wiki
Generate a local project wiki and keep it aligned with meaningful Git changes through Numar’s Wiki workflow.

Why Numar
Why developers choose Numar.
Why Numar
I work across 3 separate repos daily, and Numar’s Cross-Stack Agents changed everything. I can query my backend APIs right from the frontend workspace without switching tabs or polluting context. The suggestions finally make sense because it sees my full stack, not just one isolated window.

Full-Stack Engineer
Numar Test turned my workflow around. Every edit triggers tests automatically, and failures feed back to the agent to fix itself. I barely have to debug trivial issues anymore—Numar catches them before I even notice. My PRs now go through on the first try more often than not.
As someone working on sensitive internal tools, the zero-cloud BYOK model is a game-changer. My code never leaves my machine or gets sent to Numar’s servers, but I still get full AI capabilities. It’s the only AI IDE I feel safe using with proprietary code.
Full Memory makes every conversation feel like it’s picking up where I left off. It remembers past decisions, API designs, and even my style preferences. No more repeating context every session—it’s like working with a teammate who’s always caught up.
Sarah Chen
Senior Engineer
The Phase Models feature is brilliant. It uses reasoning models for architecture planning and fast code models for writing, exactly when I need them. No more overpaying for heavy models on simple tasks, or getting shallow answers from lightweight ones on complex problems.
Tomás Silva
Senior Backend Engineer
Numar Wiki is the unsung hero. It documents my codebase automatically and syncs with every meaningful Git change. No more stale READMEs or outdated comments—when I forget how a module works, I just check the wiki, and it’s always up to date.
