For now, yes. Nodeway is free to download and use with no account while it's new, and that may change later. AI features use your own API key.

Which languages and frameworks does it understand?

TypeScript and JavaScript through the TypeScript compiler, and Python, Go, Rust, Java, C#, C/C++, Ruby, PHP and Shell through tree-sitter. It finds routes in 13 frameworks and tables from 8 ORMs.

Can it show what a change will affect?

Yes. Open Changes and click Show impact, or press ⇧D. Nodeway lights up the functions your branch or uncommitted work changes, then everything that calls them: the routes, components, tables and tests within a few hops. You can also paste a GitHub pull request link to see a PR's impact without checking it out, and copy the summary into the PR as Markdown or a Mermaid diagram.

Which AI providers can I use?

Anthropic, OpenAI, Google Gemini, OpenRouter or Ollama, with your own key. Ollama can also run on your own machine with no key. Without any of these, everything except Ask and explanations works offline.

Why does macOS or Windows warn me the first time I open it?

The builds aren't signed yet. On a Mac, open System Settings → Privacy & Security and click Open Anyway. On Windows, click More info → Run anyway.

Can I install it with Homebrew?

Yes, on a Mac: brew install nodewayhq/tap/nodeway. Nodeway updates itself after that, and you can remove it with brew uninstall nodeway.

Does it run on Linux?

Not yet. Today it runs on Macs with Apple silicon and on Windows 10 and 11 (x64).

Nodeway checks for a new version when it starts and every few hours. When one is out, click Update: it downloads, checks the file against a published checksum, and restarts Nodeway with the new version.

Find your way around code you didn’t write.

Nodeway is a desktop app, free for now, that turns any repo into an interactive map of its files, functions, routes and database tables. Click a route to see every function and table it touches, with the code right beside it.

Workflow

Get from question to code in seconds.

Four moves cover most of what you need to understand a codebase you didn't write, or one you wrote a year ago.

Find anythingSearch, or just ask

Search every file, function, component, route and table at once, ranked as you type. Or ask a question in plain English.

⌘K

The search palette for passkey, with the Passkey table first, then files, components and functions

Built from the real code.

Every line on the map comes from a real import, call, route or query, not from file names or a model's guess.

Type-checked calls. TypeScript goes through the real compiler, so calls resolve through imports, classes and dependency objects.
Ten more languages. Python, Go, Rust, Java, C#, C/C++, Ruby, PHP and Shell are parsed with tree-sitter.
Routes and tables included. HTTP routes from 13 frameworks and tables from 8 ORMs land on the same map as the code.

Features

Everything you need to find your way.

Static analysis under the hood, a fast map on top, and the code one keystroke away.

See what a change reaches

Light up every function a branch or pull request changes, then everything that calls it: the routes, screens, tables and tests within a few hops. It opens instantly.

Review pull requests

Open any pull request and get a brief: what to read first and why, how the change flows, and a short summary. Comment on lines, approve and merge without leaving the map.

Walk through a change

Press W on any pull request and Nodeway walks you through it one step at a time, in the order a request flows. The camera moves to each changed function, route, page or table, and each step explains the change part by part, beside the lines that changed.

Askabout shop

Ask Nodeway

Ask how something works in plain words. The answer is drawn from the map itself, so it links to the files, functions and tables involved and shows the path between them, one click from the code.

Privacy

Your code stays on your machine.

Nodeway is a desktop app. It reads your repository where it lives and keeps everything it learns about it on your computer.

Analysed on your computer

Your code is read and mapped locally. Nothing is uploaded to build the map.

Private by default

The Nodeway server only listens on 127.0.0.1, so nothing else on your network can reach it.

Explanations and Ask use your own key for Anthropic, OpenAI, Gemini, OpenRouter or Ollama, or Ollama running on your own machine. Leave it out and Nodeway works fully offline.

Languages

Works with the stack you already have.

Eleven languages are read down to functions, imports, calls, routes and tables. Mixed repos land on one map, so a Go API and a TypeScript frontend sit side by side.

Accuracy

Checked against the compiler.

We ran Nodeway on real open-source projects and compared every call it linked with what the language's own tooling says is true. These are the results.
