José Almeida 89332e1cbb fix: render passthrough terminal in quick chat (#744)
* fix(backend): start agent immediately for passthrough quick-chat sessions

Passthrough profiles need a running PTY for the terminal to attach. When
launchPrepare is called with a passthrough profile, upgrade the request to
launchStart so the PTY exists by the time the frontend renders the terminal.

* fix(web): render passthrough terminal in quick chat for passthrough profiles

Quick chat used MessageList + ChatInputArea unconditionally, so passthrough
profiles showed an empty chat with no agent output (PTY never attached).
Render PassthroughTerminal when the active session is passthrough, mirroring
the task-page branch. Passthrough is detected via session.is_passthrough or,
before WS hydrates, via the agent profile's cli_passthrough flag — looked up
through a new agentProfileId stored on quickChat session entries (set by the
picker on selection and seeded by SSR for restored sessions).

* style(web): apply prettier formatting

* fix(web): address review feedback on quick-chat passthrough rendering

- Narrow `metadata.agent_profile_id` to string at runtime via a
  `readAgentProfileId` helper instead of a blind type cast.
- Collapse `useIsQuickChatPassthrough` into a single `useShallow`
  selector to avoid three separate store subscriptions.

* fix(backend): prevent launchPrepare ↔ launchStart recursion for passthrough

When passthrough quick-chat sessions hit a workflow step that blocks
auto-start, launchStart's downgrade to launchPrepare would have re-upgraded
back into launchStart and looped forever. Skip the passthrough upgrade when
AutoStart=true, since that flag uniquely identifies the downgrade path.

Adds tests for `isPassthroughProfile` and a regression test that runs the
launchStart→launchPrepare path under a deadline so future recursions surface.

* test(web): cover existing agentProfileId preservation on reopen

* style(web): apply prettier formatting

* test(backend): seed task with blocked workflow step in recursion regression

Without persisted task and step, shouldBlockAutoStart short-circuited to
false, the test bypassed the launchStart→launchPrepare downgrade entirely,
and removing the recursion guard would still pass. Seed the task with a
WorkflowStepID mapping to a step lacking auto_start_agent so the guard is
the only thing preventing the bounce. Verified by temporarily removing the
guard — the test now times out as expected.

* test(backend): cover ResolveAgentProfile error path in isPassthroughProfile

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
  • 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
  • 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

Supported ACP Agents

Agent Protocol
Claude Code ACP (@zed-industries/claude-agent-acp)
Codex ACP (@zed-industries/codex-acp)
GitHub Copilot ACP
Gemini CLI ACP
Amp ACP (amp-acp)
Auggie ACP
OpenCode ACP

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

npx kandev

This downloads pre-built backend + frontend bundles and starts them locally. The worktrees and sqlite db will be created in ~/.kandev by default. Should work 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

    UI[Web UI] --> Backend


        Backend["Backend (Orchestrator)"]


    Backend --> W1 & W2

    subgraph W1[Local Process]

    end

    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, and OpenCode 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.
