1DevTool vs Synara
Integrated dev toolchain vs free open-source agent workspace
1DevTool
1DevTool is a multi-agent AI workspace that runs Claude Code, Codex CLI, Gemini CLI, and any CLI agent in parallel persistent terminals, each in its own Git worktree. Beyond chats and diffs it ships a full toolchain — Monaco editor, HTTP client, 13-engine database client, embedded browser, and Docker — all wired into Send-to-AI. Bring your own keys, run offline with no account, pay once at $29.
Synara
Synara is a free, open-source desktop app that unifies AI coding agents in one workspace — chats, terminals, browser previews, inline diffs, Git branches, and model handoffs in a single window. It runs eight harnesses (Claude Code, Codex, Gemini, Cursor, OpenCode, Grok, Kilo Code, Pi), each keeping its own models. Built for parallel work: split chats and isolated Git worktrees, mid-thread model switching that passes context between agents, a one-click PR the moment an agent finishes, and scheduled Automations. Local-first, no sign-up — use the AI subscriptions you already pay for.
