Claude Code, Codex, Gemini CLI and 12 more, running in parallel across every project, in one window that sees your whole dev context.
Trusted by developers shipping with AI daily →Five agents, four terminal tabs, three projects, and you in the middle: copy-pasting context, checking who is stuck, re-typing prompts after every rate limit.
A typical Tuesday afternoon
Charts are org charts and pipelines for your terminals: who reports to whom, who hands work to whom. Watch what happens to one prompt, beat by beat.
You talk to Director only. Everything below is briefed by Director, not by you.

BackendRate limits, quota cuts, and crashed CLIs are the weather of 2026. 1DevTool plans for them: every seat on a chart can name its own backups, and work routes around a dead agent instead of stopping.
Open a seat in the Charts builder and name up to three backups: if Codex dies here, OpenCode takes the seat, then Pi. Each backup launches with its own startup preset and receives the conversation so far.
Give any type of work an ordered list of engines and choose which failures move it along: launch error, rate limit, quota exhausted, no response. Active teams show the hop that happened.
Only a process that actually died triggers failover. Closing a tab, quitting the app, or restarting a terminal yourself never counts as failure. A seat that changed hands says so, in plain words, on the live team.
Every signal in your workspace is one click away from your agent. No copy-paste, no context lost between tabs, no restart-and-rebuild after a crash.
Fire one prompt at many agents at once. Run Claude Code, Codex, Gemini CLI, or any AI CLI in parallel across terminals and projects. @ mention another agent right in your prompt: ask Codex to review what Claude just shipped.
Any agent terminal reads as a clean chat. When an agent asks one of those multiple-choice questions, Conversation shows it as an interactive card: pick options, type an answer, review, submit. Team hand-offs render as tidy rows, not raw CLI noise.
Every AI change lands in a side-by-side diff panel. Accept the good edits, reject the bad ones, edit inline, or send a follow-up, all without leaving the workspace. No more blind merges from your agent.
Pair your phone with a QR code and take every agent with you. Watch terminals live, send prompts with @ file mentions and images, approve permission requests, and get a push notification the moment an agent finishes, over Wi-Fi or from anywhere via a secure tunnel.
Live usage bars show every agent's 5-hour and weekly quota right in your status bar. Save multiple accounts per agent, and 1DevTool auto-switches to the healthiest one when you cross a threshold, no logout dance, no lost session.
One click sends console logs, network requests, errors, and screenshots straight to your AI agent. No more switching between Chrome and your terminal 20+ times a day.
A rich prompt editor built right into your terminal. @ mention files, drag-and-drop images, format with markdown, compose the perfect prompt without ever switching apps.
Quit mid-build, restart your machine, come back hours later, every terminal session is exactly where you left it. Scrollback, running processes, agent conversations. All still there.
1DevTool ships an MCP server that exposes your saved database connections and HTTP requests to any agent. Claude can query your Postgres, preview tables, inspect schemas, and fire saved API requests by itself, with live tool-call badges on the terminal so you see every call.
Agents take 10 seconds to 5 minutes to respond. 1DevTool sends a native notification the moment any agent is done, and the Activity feed shows every completion and every AI-generated file across all your projects, click any event to jump straight to that terminal.
Everyone runs parallel agents in 2026. The difference is what surrounds them: failover, drawn charts, a full workbench, your own subscriptions, and a price that is not a meter.
Feature reading as of August 2026. First-party CLIs run their own vendor's models; Conductor is macOS-only; Warp and Cursor meter usage through credit plans.
tmux, VS Code, Postman, TablePlus, Sublime Text: every tool in your dev stack lives in its own window. 1DevTool fuses them into one workspace with AI built in.
Most devs glue together a stack of single-purpose apps: tmux + iTerm for terminals, VS Code or Sublime Text for editing, Postman for HTTP, TablePlus for databases. 1DevTool combines all five into one workspace, with parallel AI CLIs, rich prompts, and cross-tool context built in, for a one-time $29. No subscriptions, no per-tool seats.
Real users, real names, linked to their sites.
"1DevTool has gotten really impressive. The UX redesign feels much more intuitive. I use the app every day, and seeing consistent updates like this gives me real confidence in it."
"Running Claude Code + Codex across 3-4 projects used to mean a desktop of terminal tabs. 1DevTool puts every project (terminals, browser, HTTP client, DB) in one window, and remembers exactly where each agent left off when I close the app. $29 once, replaces my whole AI dev stack. Best price-to-performance in the market."
"As a fullstack software developer, I use AI to assist with coding almost constantly, every single day — choosing to use and pay for 1DevTool has been the perfect choice for my work. I've been using 1DevTool since day one, and I really appreciate the support as well as the guidance on how to use the app. The developer has always strived to improve and update 1DevTool in the best possible way, based on users' needs. I've also just paid for the 1FileTool app to support my work. Thank you so much, 1DevTool."
"I work with multiple AI agents and projects simultaneously every day. 1DevTool is the first workspace that makes this setup actually manageable. Being able to run and monitor many terminals in parallel while keeping each project organized in its own persistent workspace saves me a huge amount of time and mental overhead."
1DevTool never sits between you and your AI: your Claude, OpenAI, and Google subscriptions stay yours, with no credits and no markup. Pay once for the workbench when you need more room.

Claude Code, Codex, Gemini CLI, Cursor, Grok, Kimi Code, Antigravity, Hermes, Pi, Amp, OpenCode, Cline, Qwen Code, and Aider, plus bash, zsh, and PowerShell. You can define custom commands too: if it runs in a terminal, it works in 1DevTool.
They all run agents in parallel now; the difference is what surrounds them. 1DevTool runs the first-party CLIs locally on your own subscriptions (no credits, no markup), lets you draw org charts and pipelines for how agents hand work to each other, fails a dead seat over to a backup agent automatically, and bundles the editor, browser, HTTP client, database client, and phone remote in the same window. It runs on macOS, Windows, and Linux for a one-time $29.
Two safety nets. Per seat: any seat on a chart can name up to three backup agents; when the primary's process dies (a crash, an out-of-quota exit), the next backup opens in that seat and receives the conversation so far. Per type of work: fallback chains route unnamed work to the next engine when a run fails, and Active Teams shows the hop that happened. Closing a tab or quitting the app never counts as a failure.
Yes. Pair your phone by scanning a QR code, over your local network or from anywhere via a secure Cloudflare Tunnel (works on LTE). You can watch terminals live, send prompts with @ file mentions and image attachments, approve permission requests, browse and edit files, use the git client, run HTTP requests and database queries, and get push notifications the moment an agent finishes.
Yes. macOS (Apple Silicon + Intel), Windows 10/11 (NSIS installer + portable exe), and Linux (AppImage + .deb). Full PTY terminal support on all platforms. Tmux-based session persistence is available on macOS and Linux.
No subscription, one-time payment. Your license includes 1 year of free updates. After that, the app keeps working forever, you just won't receive new feature updates unless you renew. Licenses are per-device (1, 3, or 5 devices depending on your plan) and you can deactivate and move them anytime.
If the model has a CLI interface, you can run it as a terminal in 1DevTool. There's no built-in integration with Ollama or LM Studio specifically, but any command-line tool works as a custom agent.
23 database engines across SQL (PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, CockroachDB, ClickHouse, TimescaleDB, Hydra, Neon, Supabase, Amazon Redshift), NoSQL (MongoDB, Elasticsearch, CouchDB, Cassandra), cache (Redis, Valkey, KeyDB), vector/multi-model (SurrealDB, Weaviate), and specialized (InfluxDB, Apache Kafka). Each has schema browsing, query execution, and export support.
Pipelines let you chain AI agents together across multiple terminals. You can set up conditional branching (regex match, contains), delay and checkpoint nodes for human approval, output capture modes (full, regex, last N lines), and transform operations between steps. Great for multi-step workflows like Plan → Review → Revise with different AI agents at each stage.
Yes, a permanent free tier with no time limit. You get unlimited prompts to AI terminals, Agent @mention orchestration, 1 project, 4 terminals, 1 browser tab, 1 git worktree, 1 database connection, 5 saved HTTP requests, 5 AI diffs per day, and 7-day prompt history, resume & memory. All platforms supported. No credit card required.

Yes, 1DevTool ships a built-in MCP server that exposes your workspace to any MCP-capable agent. Your agents can query your saved database connections (query, preview_table, describe_schema), run your saved HTTP requests with environments, and more, with live MCP tool-call badges on the terminal so you always see what the agent touched.
The embedded browser can capture screenshots (including lazy-loaded content and JS state), annotate them with a built-in markup tool, and send the annotated screenshot plus URL context and console logs directly to any AI agent running in your terminals, all in one click.
1DevTool adds project-level persistence with named agent sessions, a file tree, a built-in database client supporting 23 engines, an HTTP client, an embedded browser with screenshot annotation, Send-to-AI integration, agent orchestration, and smart notifications. tmux doesn't know what project you're in; 1DevTool does.
Run every coding agent like a team: drawn charts, automatic failover, one window that sees your editor, browser, HTTP client, and database. And a phone in your pocket that sees all of it too.
