About tterm

tterm is a macOS application that combines a terminal, a real Chromium browser, and Claude Code into one interface. It replaces the traditional editor with a diff review workflow where you inspect changes hunk by hunk before committing. The tool is free for hobbyists, runs on Apple silicon, and requires no account or telemetry.

Review

tterm rearranges the coding workflow around Claude Code by removing the editor entirely. Each project appears as a row containing an explorer, a Claude pane, and a file viewer. The embedded Chromium browser carries over your Chrome bookmarks and cookies after a one-time Keychain consent prompt, and the Claude agent can drive that browser.

Key Features

• Project rows that group an explorer, Claude pane, and file viewer
• Embedded Chromium browser that copies Chrome bookmarks, history, and cookies into its own profile
• Diff review hunk by hunk-no built-in text editor
• Self-rebuilding capability: ask the Claude pane for a feature and the running app hot-reloads with it
• Runs locally on Apple silicon with no account and no telemetry

Pricing and Value

tterm is currently free for hobbyists on Apple silicon. The creator has not announced any paid tiers. No account creation or telemetry collection is required.

Pros

• Combines terminal, browser, and Claude Code in one application window
• Self-rebuilding: you can request features from the Claude pane and the app hot-reloads without restarting
• Browser integration copies Chrome data after a one-time Keychain consent prompt, leaving the original Chrome profile untouched
• Diff-by-hunk review encourages deliberate commit practices
• No account or telemetry required

Cons

• No built-in editor-developers who prefer to write or modify code directly won't find that here (by design, but a limitation for some)
• The agent can drive the browser against signed-in sessions without an origin allowlist, which increases the risk of unintended actions on real accounts
• Hot-reloaded changes have no automatic rollback; if a feature breaks the app, you must issue another prompt to fix it (checkpointing is not yet implemented)

tterm fits developers who already center their workflow on Claude Code and want a single window for prompting, browsing, and reviewing diffs. It's less suited for those who need a traditional code editor or stricter isolation between agent-driven browser actions and authenticated sessions. The self-rebuilding design and local-only operation make it a distinct option for experimenting with AI-assisted development on macOS.
