An AI agent that writes code, manages files, uses git and automates your work. 100% local, zero cloud, zero cost. Web UI + Ollama, ready in 2 minutes.
Writes code, runs commands, versions, protects your files and learns your project.
Scans your project and builds a persistent profile: stack, conventions, linter, test framework, structure. The agent writes code that respects your style.
Smart templates that adapt to your stack. React? It suggests components. Python? It offers venv and tests. Zero configuration.
It doesn't stop at the first response. Executes up to 10 consecutive tool-calling turns to complete complex tasks autonomously.
Status, diff, commit and log right from the sidebar. No terminal, no context switching.
Every action creates an automatic snapshot. If something goes wrong, roll back with one click. Zero risk.
The agent only accesses the folders you grant. Three permission levels with real enforcement: writes limited to workspace, MCP tools only in full-access, built-in anti-escalation.
bash, read_file, write_file, edit_file, list_directory, search_files, glob_search. Everything you need to work on code.
Saves notes and context in .lobster/context.md within your workspace. Notes, decisions and preferences persist across sessions.
Every change shows a line-by-line diff. You always know what changed, before and after.
Connect external tools via Model Context Protocol. Database, GitHub, Slack, browser — one JSON file and the agent uses them as native tools.
Protected system paths, blocked destructive commands, atomic writes, anti-escalation. The agent cannot self-promote or break your OS.
Responses arrive word by word via Server-Sent Events. Watch the agent think and act in real time.

Not a chatbot. A colleague that executes, versions and protects your work.
Creates complete structures with context-awareness. The agent detects the stack and adapts its actions accordingly.
Reads the code, finds the bug, fixes it with a diff preview and creates a snapshot for rollback.
Automatic snapshot before every change. If you don't like the result, roll back with one click.
Processes CSV files, generates charts, computes statistics. All local — your data stays yours.
Commit, branch, log from the UI. Automatically generates changelogs by analyzing recent commits.
HTML, CSS, JS — components, animations, responsive. Shows a diff for every file it touches.
"The best tool is one that never asks you to leave your flow. Lobster lives where you work — in your files, with your data, all local. No cloud spying on you, no subscription holding you back."
