The workspace for agentic coding
Agentic coding is the workflow of the era: AI agents that plan, write, test, and debug code autonomously while you review. 1DevTool is the desktop workspace purpose-built for it — parallel agent terminals, tmux-backed persistence, Agent Pipelines, and Send-to-AI from every tool in the stack.
$29 one-time after beta. macOS, Windows, Linux.
Sound familiar?
Agents need room to work, not a terminal tab
A long Claude Code or Codex plan can run for 20+ minutes. Squeezed into an iTerm tab, you can't monitor progress or juggle parallel agents.
Multiple agents, multiple projects
Real agentic coding is Claude planning in one pane, Codex implementing in another, Gemini writing docs in a third — across three repos. Organization is critical, not optional.
Traditional tools weren't built for this
VS Code, iTerm, and Terminal.app were built before agentic coding existed. They're playing catch-up — AI agents are sidebar plugins, not first-class panes.
No cross-tool context for agents
Your agent writes an endpoint. Now you need Postman, DB client, and Chrome to verify — and the agent can't see any of those results unless you screenshot and paste.
No way to chain agents automatically
Agentic workflows want planner → implementer → reviewer pipelines. Running that manually across three terminals means you're the glue, losing the point of agentic coding.
Built for the agentic era
- Dedicated persistent terminals for Claude Code, Codex CLI, Gemini CLI, Amp, Aider
- 2×2 grid layout to watch multiple agents work simultaneously
- Agent Pipelines chain agents automatically (planner → implementer → reviewer)
- Tmux-backed sessions on macOS/Linux — agents resume exactly where they stopped
- Send-to-AI from the HTTP client, DB client, and embedded browser straight into any agent
- Per-project workspaces with full-state persistence for multi-project agentic workflows
Everything you need for agentic coding
Agent-Native Design
Every feature built for autonomous AI agents — not a terminal emulator with AI bolted on. Terminal Dashboard shows each agent's state: running, waiting, completed.
Multi-Agent Monitoring
Run Claude Code, Codex CLI, Gemini CLI, and Amp simultaneously. See all their work in one window, one grid.
Persistent Agents
Tmux-backed on macOS/Linux. Agent sessions survive restarts, crashes, and closed laptops. Pick up exactly where they left off.
Agent Pipelines
Chain agents automatically: planner → implementer → reviewer. Define the pipeline once, run it across any repo.
Send-to-AI
One-click sends screenshots, HTTP responses, DB query results, and console logs straight into the agent's input. No copy-paste, no screenshot juggling.
Project Workspaces
Agentic workflows per project. Switch contexts without losing agent state, open terminals, or conversation history.
Frequently asked questions
What is agentic coding in 2026?
Agentic coding is when AI agents autonomously plan, write, test, and debug code — not inline completions, but full multi-step workflows. Tools like Claude Code, OpenAI Codex, Sourcegraph Amp, and Aider are the standard agentic tools. 1DevTool is the workspace built to run them.
What's the best agentic coding workspace?
1DevTool is purpose-built for agentic coding: parallel agent terminals, tmux-backed persistence, Agent Pipelines, and Send-to-AI from HTTP/DB/browser. For single-agent inline workflows, Cursor or Windsurf are closer fits.
How does 1DevTool support agentic coding?
Dedicated persistent terminals for AI agents, 2×2 grid layouts to monitor parallel agents, Agent Pipelines for chained workflows, Send-to-AI integration from every tool, and per-project organization. Everything agentic workflows need.
Which AI agents work best for agentic coding?
Claude Code (Anthropic), Codex CLI (OpenAI), Gemini CLI (Google), Sourcegraph Amp, and Aider are the leading picks. 1DevTool runs any CLI-based agent — including local models via Ollama.
Can I run multiple agents in parallel?
Yes. That's a core 1DevTool feature. Claude Code in one pane, Codex CLI in another, Gemini CLI in a third — all visible at once in a grid. Agent Pipelines can also chain them automatically.
Do agent sessions survive a reboot?
On macOS and Linux, yes — sessions are tmux-backed. Agents resume exactly where they stopped. On Windows, sessions restore on app relaunch.
Does this replace my editor?
It can. 1DevTool ships Monaco (same engine as VS Code) with LSP for 10 languages. Or use 1DevTool alongside VS Code/Cursor — agents in 1DevTool, editing in your editor of choice.
How much does it cost?
Free tier available. $29 one-time for unlimited use. No subscription. Agent API usage billed separately by Anthropic, OpenAI, or Google.
