This is the lightest-weight way to do concurrent work in Firebender. Chat tabs example ## When to use Tabs * **Quick, unrelated changes**: Two or more small tasks in different files that are unlikely to conflict * **Read-only exploration**: Ask one tab to search, summarize, or trace code while you implement in another * **Short feedback loops**: Iterate on a doc, config, or UI detail while another tab does small follow-ups ## What Tabs are not * **Not isolated**: Tabs share the same working directory and git state * **Not safe for conflicting edits**: Two tabs editing the same files can create merge pain If you need isolation for features or PRs, use [Parallel agents](/multi-agent/worktrees) instead.
