Give her a name, an email, a username, a domain, or a photo. She opens a case, runs the target across the open web, reads the metadata, maps the infrastructure, and draws everything she finds into a knowledge graph that grows while you watch. Runs on macOS and Windows, powered by Claude, ChatGPT, or a local model of your own.

Seriously. Aether is for people and systems you're actually allowed to look into: your own exposure, folks who asked you to check theirs, and lab or CTF boxes you own. She only reads what's already public or shown by a platform. She won't break authentication, get past bot-detection, phish, or take over accounts, and those limits are baked into how she works. Point her at a stranger you have no business investigating and you're the baddie, not her. Be normal.
You hand Aether a selector and she gets to work, writing up what she finds rather than firing off chat replies.
Every tool she runs shows up as a numbered line in an evidence log that stays with the turn — so a finding has an
address you can cite later, like 02.1. The moment she finds something she writes it into the graph, then flips its
status as she confirms it or rules it out.
The graph encodes meaning rather than decorating with it. Shape is the selector type — circles for identity, squares for infrastructure, diamonds for artifacts, triangles for contact details. The ring is the status: a solid ring is confirmed, a ring broken at twelve o'clock is an open lead, dashed is a candidate, and an excluded node is hatched and struck through. Roman type is established, italic is provisional. All of it survives a greyscale screenshot, and all of it reads the same in either theme. Nodes carry real pictures too: a face on a person, the site's favicon on an account, the photo itself on a photo node.
Every turn is numbered and every tool call sub-numbered beneath it. Your words are kept verbatim in mono; her report is set in sans against a margin rule.
Selecting a node brackets it, draws a crosshair through it, lights its neighbourhood and drops everything else back a value step.
A first-class light theme, not an inverted dark one. The canvas is drawn from the same tokens as the rest of the app, so it repaints instantly when the theme changes.
One list, grouped by the question each capability answers. The switch says you want it — if it needs a program installed, turning it on installs that first.
Run her on Claude, on ChatGPT, on Gemini, or fully local through Ollama. Same tools, same graph, your choice of brain.
A live knowledge graph. A force-directed canvas you can pan, zoom and drag. Marks are shaped by selector type, ringed by status, sized by how connected they are, and carry real pictures where there are any. A node written mid-turn pulses one expanding ring, so you can see which of the four things a tool just reported actually landed. It's the main workspace, and it updates as the case builds.
A transcript you can cite. Answers stream in as she writes them, and every tool call is a numbered line in an evidence log that is stored with the turn instead of vanishing when it finishes.
Light and dark, both first-class. One palette, defined twice, with every pairing contrast-checked. The graph canvas reads from the same tokens as the DOM, so switching theme repaints it with no reload.
Modules that tell you the truth. Roughly twenty bundled modules drive a command-line program — maigret, subfinder, nuclei, nmap and friends — and a module whose program is missing is a tool that always fails. So install state and enable state are one thing: the switch says you want a capability, and turning it on installs whatever it needs first, using whichever package manager you actually have (Homebrew, pipx, go install, gem). A module can no longer be switched on while its program is missing. First launch offers to do the lot in one click; it's recommended, not required, and it doesn't appear at all if there's nothing to install.
Two things it will not do: run anything as root, or install without a click. When the only route needs sudo,
you get the exact command to paste instead of a shrug. And because a GUI app inherits launchd's bare PATH
rather than your shell's, Aether repairs PATH at startup — Homebrew, ~/.local/bin, ~/go/bin, ~/.cargo/bin
and the rest — then asks your login shell for the real thing, so tools installed with a version manager are
found too. That single fix is the difference between "installed" and "command not found".
A built-in Sherlock. username_search checks a handle across dozens of platforms at once, no Python and no
setup, and tells you where a public profile exists.
Dozens of bundled tools. A big catalog of no-key OSINT and recon endpoints (GitHub, crt.sh, RDAP, DNS over HTTPS, Shodan InternetDB, RIPE, Wayback, urlscan, OTX, Hudson Rock and more), plus one-toggle wrappers for the usual recon CLIs (maigret, subfinder, httpx, nuclei, nmap). Add your own too: a local command, or any HTTP API called with your keys, which get encrypted on your machine and never leave it in plaintext.
Offensive-security playbooks. A bundled set of skills (network recon, web enumeration, foothold, privilege escalation, password attacks, an HTB methodology) the model loads when a lab or CTF task calls for it.
Aether isn't locked to one model. Pick your provider in Settings, and the model switch is right there in the chat, next to where you type.
| Provider | What it is | Needs |
|---|---|---|
| Claude | The default. Uses your Claude subscription through the Agent SDK. | Sign in once |
| ChatGPT | Any OpenAI-compatible endpoint (OpenAI, Azure, OpenRouter, a proxy). | Your API key |
| Ollama | A model running fully on your own machine. Nothing leaves the box. | ollama serve + a tool-capable model |
The graph, the tools, and the whole workflow are identical whichever you choose. For the local route, use a model that supports tool calling (llama3.1, qwen2.5, mistral-nemo); ones without it will still chat but can't drive the graph.
git clone https://github.com/fknMega/Aether.git
cd Aether
npm install
npm run devOn Claude, the first launch walks you through signing in (or run npm run login). On ChatGPT or Ollama, drop
your key or point at your local server in Settings and go. You'll need Node 18+; there's no database to run and
no native toolchain to install, and state is a plain JSON file.
There's a flake, so nix develop gets you a shell with the right Node, the nixpkgs Electron (no postinstall
binary download), and — on Linux — the Chromium runtime libraries that otherwise fail at window creation.
nix develop # dev shell, then: npm install && npm run dev
nix build # Linux package; see the note in flake.nix about npmDepsHashflake.lock is not committed — run nix flake lock once, or let nix develop generate it, so the pin is
yours rather than one baked in by whoever wrote the flake.
npm run dist:mac # .dmg and .zip, built on macOS
npm run dist:win # .exe installer, built on WindowsBuild each OS on that OS, since the claude binary ships as a per-platform package. Output lands in release/.
Auto-updates work on both Windows and macOS, and there's an Updates panel in Settings (check, status,
install, auto-check toggle). Aether reads the latest GitHub Release,
downloads the build in the background, and installs it: on Windows it runs the new installer, and on macOS it
swaps its own app bundle and relaunches (no code signature required, unlike the stock Electron updater). If the
app lives somewhere it can't write, it falls back to opening the .dmg for a quick drag. To publish a build,
create a Release with the .dmg / .exe assets attached (e.g. gh release create v2.0.2 release/* with a token
that has contents:write).
Does the AI get its own environment, or can it wreck my machine? It gets one. Command execution runs inside an OS-level sandbox — Seatbelt on macOS, Bubblewrap on Linux — and there are three more layers above it:
| Layer | What it does | Enforced by |
|---|---|---|
| OS sandbox | Isolates command execution from the rest of the account | the kernel |
| Read boundary | File reads cannot leave the workspace, in any permission mode | the Agent SDK |
| Policy | Refuses paths outside the workspace, a credential deny-list, fail-closed on anything it can't parse | src/main/permissions.ts |
| Tool removal | In safe mode the shell and write tools are stripped from the model's context entirely | the Agent SDK |
Safe mode is the default. Autonomy — the shell, file writes, and local-command modules — is off until you turn it on. With it off, Aether keeps search, recon, the graph and API modules, and cannot execute anything.
Some things stay off-limits whether or not autonomy is on: SSH, GPG, AWS, gcloud, Kubernetes and Docker
credentials; browser profiles, cookie stores and saved logins; shell history and .env files; and Aether's own
settings, module keys and sign-in tokens. The boundary is asserted by tests, not just described — see
permissions.test.ts and run npm test.
Prompt injection is the real threat here, and it is not hypothetical. Aether's whole job is reading content written by the people it investigates, so a target who expects to be looked at can plant instructions where Aether will read them. The system prompt tells the model that every byte returned by a tool is evidence and never an instruction, and to report an attempted injection as a finding. That plus the sandbox is a serious mitigation, not a solved problem — the layers exist precisely because the prompt alone is not enough.
What is still on you. Custom modules are trusted config: only add ones you wrote or trust, because a command module is a shell command you asked for. Keys, both for modules and for your AI provider, are encrypted at rest with the OS keychain and never sent to the renderer in plaintext.
On Linux the sandbox needs bubblewrap; with autonomy on, Aether refuses to start a turn rather than silently
run unsandboxed. On Windows there is no sandbox backend at all — autonomy there gets the read boundary, the
policy and tool removal, but not kernel isolation. That is a real gap, and it is stated here rather than
papered over: if you run with autonomy on Windows, the policy is the only thing between a hostile page and your
account.
None of this is a bug list. It's what the tool is, and open-sourcing it means you can read exactly what it does.
