Code with the ocean's flow.

DeltaCode is a coding agent in your terminal. It reads your project, plans around its conventions, and does the work with you — with a free model built in, no API key required.

What it does

A terminal agent, done properly.

One lead agent, specialist helpers

The lead agent handles the conversation and hands off to coding, research, and other specialists when a task fits them better.

Real tool use

Reads and edits files, runs commands, searches with glob and grep — every action goes through a permission prompt you control.

Free model, no API key

Delta Free Models ships GLM-4.7-Flash with a fair-use daily budget. Free to start, free to stay.

Sessions that remember

Every conversation is saved per project. Leave and come back — deltacode resumes exactly where you stopped.

MCP support

Plug in remote tool servers — Exa's web research is built in and needs no API key of its own.

Rendered like it matters

Live reasoning, boxed code blocks, tool results, and merged retry status — a terminal UI built like a product.

In the terminal

The agent at work.

Reasoning streams live, code renders in framed blocks, tool calls show their results, and the free-model budget is always a /usage away.

Install

Up and coding in one line.

DeltaCode is built for macOS. Paste the command into Terminal and the installer handles the rest — no accounts, no API keys, no waiting.

macOS
$ curl -fsSL https://raw.githubusercontent.com/wehnnit/DeltaCode/main/install.sh | bash
  1. 01

    Run the command

    One line in Terminal. The installer fetches Bun for you if it isn't there, then builds the binary.

  2. 02

    Pick a provider

    Delta Free Models needs no key — accept the fair-use statement and start. Or connect your own API key.

  3. 03

    Just ask

    cd into a project and type what you want. The agent explores, builds, edits, and verifies the result.

Prefer source? Clone from GitHub — or build straight from the repo with bun run dev.
