* refactor(backend): split terminal_handler.go into pumps/sessions/messages terminal_handler.go was 1,380 lines (1.7x the 800-line cap). Split it into four sibling files in the same package, by responsibility: - terminal_handler.go (525 lines): HTTP upgrade, route dispatch, top-level handler entries, shell-label resolution. - terminal_pumps.go (725 lines): wsWriter, bridgeBinaryWebSockets, runTerminalBridge / runUserShellBridge and all input/resize/PTY-setup helpers. Extracts replayBufferedOutput from setupPtyAccessCommon to keep nestif under threshold. - terminal_sessions.go (133 lines): execution-readiness helpers (ensurePassthroughExecutionReady, waitForRemoteExecutionReadyWithTimeout, remoteExecutionWithClientReady, shouldUseWorkspaceShell) and related timeout constants. - terminal_messages.go (53 lines): protocol primitives (ResizePayload, isResizeCommand, resizeCommandByte, stripTerminalResponses), with a top-of-file doc comment describing the binary wire protocol. Backed off the "typed TerminalMessage envelope" half of the task: the current protocol is binary, not JSON-enveloped (terminal I/O is raw PTY bytes; the only JSON is ResizePayload, sent as a binary frame prefixed by 0x01). Wrapping PTY bytes in a JSON envelope would require base64 and break xterm.js AttachAddon for every client — the task brief explicitly authorizes shipping just the file split when the format would change. Adds terminal_messages_test.go pinning the wire format: exact JSON output of ResizePayload, the 0x01-prefix detection, and a full resize-frame round-trip. These fail loudly on any accidental change to the struct tags or prefix byte. Pure relocation otherwise: no signature changes, no behavior changes, no frontend impact. * refactor(backend): simplify detectInputSubmission with bytes.ContainsAny Addresses Claude bot's PR review on #1056: replace the manual loop + flag pattern with bytes.ContainsAny(data, "\n\r"). Behavior identical (detect CR or LF anywhere in the input). Also drops the now-redundant "Check for Enter key (CR or LF)" comment. * ci: retrigger CI to re-test known-flaky session-resume spec --------- Co-authored-by: Kandev Agent <agent@kandev.dev>
Kandev
Manage and run tasks in parallel. Orchestrate agents. Review changes. Ship value.
Workflows | Run as a Service | Roadmap | Contributing | Architecture | Discord
What
Organize work across kanban and pipeline views with opinionated workflows and execute multiple tasks in parallel. Assign agents from any provider, and review their output in an integrated workspace - file editor, file tree, terminal, browser preview, and git changes in one place. Terminal agent TUIs are great for running agents, but reviewing and iterating on changes there doesn't scale.
Run it locally or self-host it on your own infrastructure and access it from anywhere via Tailscale or any VPN.
Open source, multi-provider, no telemetry, not tied to any cloud.
Vision
Humans stay in control. Define tasks, build agentic workflows with gates, review every change, decide what ships.
- Review-first - Humans support production systems. We need to understand (yet) and trust the code that gets deployed.
- Your workflow - Every team is different, and not every developer uses AI the same way. Define workflows once, share them across the team, and give everyone a consistent process for working with agents - regardless of experience level.
- Remote agents - Running multiple agents on a large codebase can quickly saturate a local machine. The goal is a single control plane: offload execution to servers, orchestrate from anywhere, including your phone.
Features
- Multi-agent support - Claude Code, Codex, GitHub Copilot, Gemini CLI, Amp, Auggie, OpenCode, Cursor, Qwen, Factory Droid, iFlow, Kilocode, Pi, Kimi, AWS Kiro, Qoder, Trae
- Parallel task execution – start and manage multiple tasks from different sources simultaneously, boosting productivity with AI agents
- Integrated workspace - Built-in terminal, code editor with LSP, git changes panel, embedded vscode and chat in one IDE-like view
- Kanban task management - Drag-and-drop boards, columns, and workflow automation
- Agentic workflows - Multi-step pipelines that mix-and-match agents per step - for example, Claude Code Opus to design a plan, GitHub Copilot Sonnet to implement it, and Codex GPT 5.4 to review the changes. See docs/workflows.md
- Sub-tasks - Agents can spawn sub-tasks that resume from the parent task's session. Useful for splitting a task that has grown too big, or producing several PRs from the same starting point.
- CLI passthrough - Drop into raw agent CLI mode for direct terminal interaction with any supported agent, leverage the full power of their TUIs
- Workspace isolation - Git worktrees prevent concurrent agents from conflicting
- Multi-repository tasks - Span a single task across multiple repositories, with one worktree per repo, per-repo branches, per-repo PRs, and per-repo grouping in the Changes panel and review dialog
- Flexible runtimes - Run agents as local processes, in isolated Docker containers or in remote executors like sprites.dev
- Session management - Resume and review agent conversations
- Stats - Track your productivity with stats on the completed tasks, agent turns, etc
Integrations
Connect Kandev to the tools your team already uses — pull issues into the kanban, link tasks to PRs, and surface review activity inline.
Supported ACP Agents
| Agent | Launch |
|---|---|
| Claude Code | npx -y @agentclientprotocol/claude-agent-acp |
| Codex | npx -y @zed-industries/codex-acp |
| GitHub Copilot | npx -y @github/copilot --acp |
| Gemini CLI | npx -y @google/gemini-cli --acp |
| Amp | npx -y amp-acp |
| Auggie | npx -y @augmentcode/auggie --acp |
| OpenCode | opencode acp |
| Cursor | cursor-agent acp (requires Cursor Pro) |
| Qwen | npx -y @qwen-code/qwen-code --acp |
| Factory Droid | npx -y droid exec --output-format acp |
| iFlow (beta) | npx -y @iflow-ai/iflow-cli --experimental-acp |
| Kilocode | npx -y @kilocode/cli acp |
| Pi | npx -y pi-acp |
| Kimi | kimi acp (install Kimi CLI from Moonshot AI) |
| Kiro | kiro-cli-chat acp (install Kiro CLI from AWS) |
| Qoder | qodercli --acp (install Qoder CLI) |
| Trae | traecli acp serve (install Trae IDE CLI) |
All agents communicate via ACP (Agent Client Protocol). Some agents support ACP natively, while others use ACP adapter packages that bridge their native protocols. CLI Passthrough mode is also available for direct terminal interaction with any agent CLI. If your agent isn't supported yet, open an issue or submit a PR with the integration. See Adding a New Agent CLI for a step-by-step guide.
Bring your own TUI agents
There is support for running any agent as TUI inside a terminal. Just add the cli command in the agent profile settings and the task will start the agent inside a PTY terminal instead of using ACP.
Supported Executors
| Executor | Description |
|---|---|
| Local Process | Runs the agent as a local process on the host machine |
| Docker | Runs the agent in an isolated Docker container |
| Sprites | Runs the agent in a remote cloud environment via sprites.dev |
Each executor uses git worktrees for workspace isolation, preventing concurrent agents from conflicting.
Quick Start
Homebrew (macOS, Linux)
brew install kdlbs/kandev/kandev
kandev
NPX
npx kandev@latest
Requires npm 7+. Installs the CLI plus a platform-matched runtime bundle in one step.
NPM (global)
npm install -g kandev@latest
kandev
Updates
brew upgrade kandevnpx kandev@latest(always uses the latest published version)npm install -g kandev@latest
The worktrees and sqlite db live in ~/.kandev by default. Works on macOS, Linux, and Windows (WSL or native).
From Source
# Clone the repository
git clone git@github.com:kdlbs/kandev.git
cd kandev
# Start in production mode
make start
Prerequisites: Go 1.26+, Node.js 18+, pnpm, Docker (optional - needed for container runtimes)
High level architecture

subgraph W2[Docker Container]
Agent2[Agent CLI] --- WT2[Worktree]
end
We also want to add support for these remote runtimes:
- Remote SSH - run agents on remote servers over SSH, using docker or local processes with workspace isolation
- K8s operator - run agents in a Kubernetes cluster, with auto-scaling and resource management.

Comparison to Other Tools
There are a few similar tools in this space, and new ones appearing everyday. Here's what sets this one apart:
- Server-first architecture - Not a desktop app. Runs as a server you can access from any device, including your phone. Start a task away from your computer and check in on it later.
- Remote runtimes - Run agents on remote servers and Docker hosts, not just your local machine.
- Multi-provider - Use Claude Code, Codex, Copilot, Gemini, Amp, Auggie, OpenCode, Cursor, Qwen, Droid, iFlow, Kilocode, Pi, Kimi, Kiro, Qoder, and Trae side by side. Not locked to one vendor.
- CLI passthrough and chat - Interact with agents through structured chat messages or drop into raw CLI mode for full agent TUI capabilities.
- Open source and self-hostable - No vendor lock-in, no telemetry, runs on your infrastructure.
