AetherSync: Your 10x Autonomous AI Coding Engineer
100% local-first execution. Zero telemetry on your proprietary code.
Works with the frontier models you already pay for — and the local ones you don’t.
Not a mockup and not a marketing render — these are live interactive simulations of AetherSync Desktop 0.1.0 running on Linux, in the light and dark themes it ships with.
Explorer, Monaco editor with real language services, an attached PTY terminal and the AI assistant docked on the right — the same window in dark and light, because the desktop app ships both themes.
This is the real interface, running in the page. Browse the file tree, open local folders, switch views, run terminal commands, and prompt the AI assistant.
Six subsystems, one shell. Follow the summary to jump straight to the part you care about.
01 — Autonomous coding
The agent reads the repository before it writes. It plans across files, applies edits as a reviewable diff and stops at every boundary you have not granted, so a refactor never becomes a surprise.
02 — Conversational pairing
Chat is grounded in the open workspace. Reference a file, a selection or a failing test and get an answer that cites the real source instead of a plausible invention.
03 — Editor workspace
Tabbed buffers, a file tree, a command palette and multi-language syntax highlighting. The AI surfaces live beside the editor, so you never trade tooling for intelligence.
04 — Sandboxed terminal
AetherSync spawns native PTY sessions — PowerShell, CMD, Bash — with streamed output and live echo. The agent may propose a command; you decide whether it runs.
05 — Model routing
Point the agent at Claude, GPT-4o, DeepSeek R1, Gemini, Mistral or a local Ollama model. Keys are encrypted in the OS keyring and never leave the machine.
06 — Trust & permissions
Every capability that touches your machine — file writes, shell execution, network calls — sits behind an explicit grant, scoped to the workspace you opened.
AetherSync is model-agnostic. Plug in your own API key or run local open-source models with zero vendor lock-in — 16 providers ship configured out of the box.
Deep reasoning, 200k context window, and industry-leading multi-file refactoring accuracy.
Target endpoint
Supported models
Privacy is an architecture decision, not a setting. Pick the mode that matches your threat model — the product behaves the same in each.
The default
The editor, the agent runtime and the terminal all execute on your machine. Workspace state is written to disk, not to a server.
Frontier models
Provider credentials are stored in the OS keyring and used to call the provider directly. Requests are not proxied, rate-limited or logged by us.
Air-gapped
Point AetherSync at Ollama or Jan and it runs with no outbound network at all — the same agent loop against a model on your own GPU.
From download to your first autonomous refactor in four steps.
Download the standalone installer and run it. Setup registers shortcuts and the deep-linking protocol for browser sign-in.
AetherSync-Desktop-0.1.0-x64.exeSign in with Google, GitHub or Discord through the browser portal — or skip accounts entirely and store provider keys locally.
Settings → API Providers → Save secret keyPress Ctrl+O to load a directory. The local sandbox indexes the file tree and prepares the integrated terminal.
File explorer: frontend / backend / mobileSwitch to the agent tab and prompt it to inspect files, run tests and apply multi-file edits — each step reviewable.
"Refactor Navbar for dark mode & run build"AetherSync started from a simple conviction: AI developer tools should be fast, deeply autonomous and respectful of developer sovereignty. Engineers deserve an editor that pairs local execution speed with frontier model intelligence — without shipping their source to someone else’s cluster to get it.
Measured on a local workspace with an Ollama model — zero network round trip in the loop.
AetherSync is popular among developers worldwide.
"AetherSync is the most beautiful code editor I've ever used. And it works as well as it looks. It's by far my best VSCode replacement right now."
"I am impressed with AetherSync. I've used competitors for a while now, I can confidently say AetherSync is my new favorite daily driver. Not only is it quick, it's stylish! I love the way it looks, refreshing to work in and extremely responsive."
"AetherSync has already reached 2.0, with a brand new look and a big splash. One reason I like AetherSync is its gorgeous, thoughtful design. These nuanced details make it feel like a carefully crafted product."
"My team has been using AetherSync for a month. It's been a pretty solid experience for the much bigger and more complex tasks where the agent actually understands our context. Productivity has gone way up."
