npm i -g futurex-cli
The AI coding agent for your terminal
FutureX is a CLI AI coding assistant that works where you already work. Describe the change in plain English — it reads the codebase, plans the job out loud, writes the code, and ships a preview. You stay in the shell the whole time.

01Live session
An AI pair programmer that reads before it writes
One prompt, one loop. FutureX opens the files it needs, states the plan, makes the edits, runs your checks, and hands back a preview. When it recognizes something from an earlier session, it says so instead of building it twice.
- REPO-AWARE
- WRITES ARE GATED
- SHIPS PREVIEWS
02How it works
Read the repo. Plan. Build. Ship a preview.
A vibe coding tool is only worth the code it understands. FutureX runs the same four beats every time, and every beat is a command you can run on its own.
01Read
It reads the repo first
futurex index builds a retrieval index over your project. futurex symbols answers where a thing is defined, futurex imports shows what it touches and what is broken. Context before keystrokes.

02Plan
It plans out loud
futurex plan writes the goal, the value and budget, the research it needs, the tooling, and a task DAG. You read the plan and argue with it before a single file moves.
futurex plan "…"
03Build
It builds against the plan
futurex build executes that plan step by step. Reads run on their own; every write asks for consent unless you have granted it a standing rule in .futurex/settings.json.
futurex build "…"
04Ship
It verifies, then ships
After the edits land it runs typecheck, lint, and tests, then ships straight to preview. Pass --no-verify when you want the checks skipped, and futurex verify to run them on demand.

03Project memory
It remembers your codebase between sessions
FutureX keeps one file at the root of your repository: futurex-memory.md. It is the agent's notebook — the decisions it made, the shape of the project it learned, written down in plain markdown. Close the terminal, come back next week, and the next prompt starts where the last one ended.
That is the difference between a chat window and a terminal AI coding agent: you stop re-explaining your own codebase every morning.
- futurex init creates futurex-memory.md at the repo root if it is missing.
- futurex compact regenerates and archives the file once it outgrows its budget — roughly 7,000 tokens.
- It is ordinary markdown: read it, edit it, commit it, review it in a pull request like any other file.
- --no-memory ignores the file for one run, when you want a clean-room answer.

One line, any terminal
FutureX ships as a single global CLI on Node 20+. Install it with the package manager you already use, sign in once through your browser, and run futurex from any project — Windows, macOS, or Linux.
Prefer one-shot? futurex ask answers and exits. futurex agent takes a task and uses tools to finish it — reads run on their own, writes ask first. The command reference has every command and flag.
