$ cat WHY_FREE.md

Kein Schlüssel. Keine Anmeldung. Keine Karte. Installieren und loslegen.

Most agentic CLIs make you paste in a provider key before they'll do anything. AlphaCode ships with a free model lane already wired in, so the very first thing you run can be a real task against a real repo.

$0

Standardmäßig kostenlos

A built-in AI provider is included and pre-configured. Nothing to sign up for, nothing to pay before your first task.

Kein API-Schlüssel zum Start

Install, launch alphacode, describe what you need. The free lane answers immediately.

⇧

Upgrade, wann du willst

Connect Claude, GPT, Gemini, Copilot, or 50+ others any time with Ctrl+T — no reinstall, same workflow.

◇

Nichts zurückgehalten

Swarm mode, desktop control, 40+ tools, browser automation — all available on the free lane, not a limited trial.

$ alphacode  # free model, already configured — no key needed

$ alphacode --help

Alles, was ein KI-Coding-Agent sein sollte.

01

KI, die Code plant, bearbeitet und prüft

Reads your codebase, plans steps, picks the best model, edits files, runs tests, and self-reviews before declaring anything done.

02

Kostenlose KI oder jedes LLM deiner Wahl

Start on the free built-in lane. Add Claude, GPT, Gemini, Copilot, Cursor, Bedrock, OpenRouter, or any OpenAI-compatible endpoint. Switch with Ctrl+T.

03

KI-Schwarmmodus mit mehreren Agenten

Big jobs split into independent pieces, run by multiple agents in parallel, then merged and reviewed automatically.

04

Eingebaute KI-Sicherheitsprüfungen

Uses safeguards for selected destructive operations and prompts for risky actions. Review requests, provider settings, and diffs before accepting changes.

05

Über 40 eingebaute Agent-Tools

File editing, regex/AST search, shell, browser control, web fetch, memory, scheduling, diagrams, PDFs. No plugin surgery.

06

Nie wieder Arbeit verlieren

Sessions saved to disk. alphacode --resume reopens exactly where you left off — even after a crash.

$ alphacode --how-it-works

So funktioniert der KI-Coding-Agent

Unlike a chat window or autocomplete, an AI coding agent acts on your project. AlphaCode follows a simple loop and stops to ask before risky actions.

01

Beschreibe das Ergebnis

Open your project, run alphacode and say what you want in plain English, such as "fix the failing login test".

02

Die KI plant und bearbeitet

The language model reads the relevant files, plans the steps, uses its tools to edit code and runs your tests to check the result.

03

Du prüfst und behältst die Kontrolle

Check the diff, accept or reject changes, and resume any session later with alphacode --resume.

$ /swarm "migrate auth to OAuth 2.1"

AI swarm mode: big coding jobs, run in parallel.

A planner agent decomposes your goal into independent DAG nodes. Multiple agents execute them concurrently — each with the right model — then results merge and review automatically.

Run swarm: "migrate auth to OAuth 2.1"

$ alphacode provider list

Kostenloser KI-Coding-Assistent. Eigenen LLM-Schlüssel nutzen, wenn du mehr willst.

The built-in free lane needs nothing from you. First-class support for the big providers, OpenAI-compatible for the long tail — anything that speaks HTTP + JSON works.

$ curl … | bash

Den KI-Coding-Agenten in einer Zeile installieren.

bash

Danach prüfen:

  1. which alphacode
  2. alphacode --version
  3. alphacode doctor
  4. alphacode

No step here asks for a key. The free provider is ready the moment install finishes. Prefer to read the script first? View install.sh.

$ ps -o rss -p $(pgrep alphacode)

Schlank konstruiert. Gemessen, nicht nur behauptet.

Compare the published historical RAM snapshots for one and ten concurrent sessions. Results depend on the operating system, build, enabled features, workload, and measurement method.

These are historical snapshots, not a universal performance ranking. Reproduce the same workload and environment before comparing tools. See the benchmark methodology and the safety model for details.

$ alphacode --examples

Was kann ein KI-Coding-Agent in deinem Terminal?

AlphaCode is an agentic CLI: you describe an outcome, it reads your repository, makes the edits, runs your tests, and reports back. Here are the jobs developers use it for most.

Fix bugs and failing tests

Point AlphaCode at a failing test suite. It reproduces the error, finds the cause with regex and AST search, patches the code and re-runs the tests until they pass.

Refactor and migrate code

Rename APIs, upgrade frameworks or move an auth system to OAuth 2.1. Swarm mode splits large migrations into parallel tasks and merges the reviewed result.

Automate Firefox and the desktop

Drive a real browser for end-to-end checks, scrape documentation, or operate desktop apps from the same terminal session you use for coding.

Connect tools through MCP

Register Model Context Protocol servers to give the agent new tools, such as security scanners or internal APIs. See the MCP guide.

Work on any server over SSH

AlphaCode is a single Rust binary with no GUI requirement, so it runs inside tmux, screen, CI runners and remote boxes just as well as on a laptop.

Choose your own model

Start on the built-in free provider, then switch to Claude, GPT, Gemini, DeepSeek, Mistral, Ollama or any OpenAI-compatible endpoint without reinstalling.

FAQ

$ man alphacode | grep -A2 FAQ

FAQ zum KI-Coding-Agenten: Deine Fragen, beantwortet.

Brauche ich einen API-Schlüssel oder muss ich zahlen?

Nein. Der kostenlose KI-Anbieter wird nach der Installation automatisch eingerichtet. Später kannst du Claude, GPT, Gemini oder ein lokales Modell über Ollama nutzen.

Does AlphaCode send code to a model provider?

AlphaCode runs on your machine, but it may send task context to the active model provider to generate responses. Which data is sent depends on the task, tools used, and provider configuration. Review provider privacy terms and avoid including secrets in prompts or files shared with a model.

Which models and providers work?

The built-in free provider works out of the box. AlphaCode also supports a range of third-party integrations and OpenAI-compatible endpoints. The available providers may change by release; check the documentation for current setup details.

Was ist AlphaCode?

AlphaCode (auch Alpha Code geschrieben) ist ein kostenloser, quelloffener KI-Coding-Agent in Rust, der in deinem Terminal läuft. Er liest dein Projekt, bearbeitet Dateien und führt Tests aus.

Ist AlphaCode dasselbe wie die Wallpaper-Seite Alpha Coders?

Nein. Alpha Coders und Wallpaper Abyss ist eine unabhängige Wallpaper-Website. AlphaCode ist ein Entwicklerwerkzeug und nicht mit ihr verbunden.

How does swarm mode work?

A planner turns your goal into a task DAG. Workers — each with their own model — execute independent nodes in parallel. A reviewer node merges and verifies the diff.

Can I use it on a remote box with no GUI?

Yes. Pure terminal. Pipe-friendly. Plays well with tmux, screen, and SSH.

How is AlphaCode different from other coding agents?

AlphaCode is MIT-licensed, includes a built-in free AI provider, supports multiple model providers, offers swarm workflows, and is written in Rust. The benchmark section provides historical memory measurements for specific test conditions; results vary by version, configuration, and workload.

What is an AI coding agent?

An AI coding agent is software that uses a large language model to complete programming tasks on your behalf. It reads your codebase, plans the work, edits files, runs commands and tests, and reports back, instead of only suggesting the next line. AlphaCode is a free, open-source AI coding agent that runs in your terminal.

Is AlphaCode an alternative to Claude Code, Cursor or GitHub Copilot?

AlphaCode is an open-source, terminal-based AI coding agent in the same category. It is MIT-licensed, written in Rust, includes a free built-in AI provider and can also connect to Claude, GPT, Gemini and other providers you already use. Compare features and privacy terms for your own workflow.

Can AlphaCode use local LLMs such as Ollama or LM Studio?

Yes. Ollama and LM Studio are listed among the supported providers, and any OpenAI-compatible endpoint can be used by setting its api_base. This lets you run an AI coding agent against a model on your own machine.
