A Ghost Developer Studio app
A fully offline AI code editor for Android and desktop.
The editor, the chat, the agent, and the autocomplete all run locally. No cloud, no API key, no account. Your code never leaves the device.
Start here: new to GhostIDE? Read the two editions, watch it run, see the real app running, then get GhostIDE.
APK, 20.5 MB. Android 7.0 and up. SHA-256: 1187a03bb5f91ba867b37a684e7e4015b27f75e63ef3008bb074d2c5f3323254
Android will ask you to allow installing from your browser, because GhostIDE is not on the Play Store yet. That prompt is expected. The hash above is printed here so you can check the file you downloaded is the studio's build.
On a computer instead? The desktop edition runs from source from the public GitHub repo: clone it, run ./start.sh, and open 127.0.0.1:5173. It needs Python 3.11 or newer and a llama.cpp build. Questions: [email protected]
One codebase and one behavior pack drive both editions, so they cannot silently drift.
Runs on Android 7.0 and up as a single APK of about 20 MB, with the AI model on the device.
Installable packages for Windows, macOS, and Linux with a one-command install. The workspace lives in a GhostIDE folder in your home directory, and it can also run from source with Python 3.11 or newer.
Run it from source instead: Python 3.11 or newer, start it with ./start.sh, open 127.0.0.1:5173, and press Start model.
The same editor, chat, agent, and tools on both editions.
CodeMirror 6 for JavaScript, TypeScript, Python, HTML, CSS, JSON, and Markdown. Tabs, split view, multi-cursor, live syntax diagnostics as you type, code folding, find and replace with regex and dry-run previews, a command palette, and Quick Open. Local history with restore, autosave draft recovery, and session restore down to cursor positions.
Streaming chat with context modes: the current file, a smart slice of its dependency web, or a project slice, with a token meter so you can see what the model is reading.
The agent plans and executes multi-file changes one action at a time. Writes stage for your review with diffs, and nothing lands until you approve it. Staged code is syntax-checked before it can be called done, runs can pause mid-run, and every run leaves a full replayable trail.
Step budgets you control, a scratchpad the agent keeps while it works, read-only EXPLORE sub-runs it can dispatch, bounded self-repair rounds when staged code fails its syntax check, and follow-ups you can queue mid-run.
A complete daily client: status with ahead and behind, stage, commit, branches, stash, tags, amend, worktrees, blame, and a log with a commit viewer. The agent's own Git surface is read-only by construction.
Discover and run Python and Node tests: the whole suite, one file, or a single test by name, then re-run only the failures. The verify pipeline reports evidence levels: Executed, Claimed, and Gaps, never a silent pass.
29 bundled Ghost tools, including GhostSlice, GhostMCP, GhostApprove, GhostIndex, and GhostReview, execute for real against your workspace. Project templates, a sandboxed plugin system, pair mode so a second device can join the workspace with a pairing token (viewers are read-only), voice coding, and optional encrypted backups.
Just the file you are in.
The file's dependency web, reason-tagged and budget-packed.
Signatures only, or full text.
The token meter shows what the model is about to read before it reads it.
Every one of them executes for real against your workspace, and the bundle only builds when all 2,871 of their tests pass.
29 tools, 2,871 passing tests.
The AI is Qwen2.5-Coder-Instruct, downloaded in the app. Every download is exact-size and SHA-256 verified before use, and resumable.
Four sizes of Qwen2.5-Coder-Instruct: the 0.5B Sprinter (380 MB download, about 0.7 GB of RAM while running) up to the 7B Max (4.68 GB download, about 5.5 GB of RAM). The 1.5B Balanced is the phone default and the 7B Max is the desktop default. The full table is in the guides: Pick a model for GhostIDE.
The desktop package contains no model; the 7B is an optional in-app download, and models can be switched at any time.
Screenshots from the actual desktop build, taken with the bundled demo project open: Trailhead, a small hike log CLI with tests. Nothing here is a mockup. The top bar shows the model as down because no model was started for these shots; the editor, the Git panel, the diagnostics, and the chat layout are all live.
How a second device joins a workspace, step by step.
You can also run the desktop build and open it from a phone browser on the same LAN, pairing with the host's code like any guest.
For trusted networks only: host-only controls stay on the host device.
GhostIDE is developed in audited campaign cycles: twenty improvements, then twenty adversarial audits against a standing checklist, released in batches of five. Four gates stand between a change and a shipped build.
Under the hood, the desktop backend is Python standard library only, with a built-in debugger bridge.
The working documents live in the repo, next to the code.
The studio publishes the app's known limits in the repo. Here is the plain version.
The full known-issues list lives in the repo.
GhostIDE collects nothing. No accounts, no analytics, no advertising, no tracking, and no studio server for data to go to.
What stays on your device: your projects and files, the model files you download, and your settings, chat history, snippets, and local file history. Deleting the app deletes this data with it.
Because the editor, chat, agent, and models all run on your device, your code stays on the device too. There is no cloud behind GhostIDE and no account to sign into, so your projects, chats, and files go nowhere unless you share or export them yourself.
It also means the editor works without a connection. On a plane, on a job site, or anywhere the signal does not reach, GhostIDE opens and runs the same as it does at your desk.
The short answers.
No. The editor, chat, agent, and models all run on your device. The internet is only used when you choose to download a model or check for updates.
No. There is no cloud behind GhostIDE and no account to sign into. Your projects, chats, and files stay on the device unless you share or export them yourself.
No. Agent writes stage as diffs for your review, and nothing lands until you approve it. Its Git surface is read-only by construction.
The app can check the repo for a newer version and report what it finds. It never downloads or installs an update by itself.
A second device can join your workspace with a pairing token. Tokens expire in 12 hours, and viewers are read-only.
Neither edition is in an app store yet. Android is a direct download from this page. Desktop runs from source from the public repo, and the studio can still email a desktop package if you ask.
