José Almeida 6fa38cd62c fix(terminal): re-key user-shell RPCs to task_environment_id (#770)
* refactor(backend): re-key user-shell RPCs to task_environment_id

user_shell.list/create/stop now take task_environment_id directly
instead of session_id with a session→env translation. Sessions in the
same task share one shell list, so the env is the natural scope.
HTTP route /api/v1/sessions/:id/terminals → /api/v1/environments/:id/terminals.
shell.status/subscribe/input (agent passthrough) stay session-keyed.

* fix(backend): heal task_sessions.task_environment_id on boot

Sessions created via paths that didn't write the FK left shell ops
broken — every env-keyed user-shell RPC failed to resolve the env and
the frontend silently swallowed the error. The boot heal links each
orphan session to its task's existing env (idempotent, runs after
backfillTaskEnvironments + healDuplicateTaskEnvironments).

* refactor(web): drop session_id from user-shell API, hooks, and slice

createUserShell/stopUserShell/fetchTerminals take environmentId.
useUserShells takes envId directly (no environmentIdBySessionId
translation). useTerminals takes both (env for shell ops, session for
tab UX persistence). Slice actions key writes by env id directly,
removing the silent no-op when the session→env mapping wasn't set yet.

* refactor(web): wire env id through dockview, right-panel, and SSR call sites

Dockview "+" menu, terminal scripts dropdown, dev-preview button,
right-panel "+" button, Ctrl+\` toggle, watermark, and panel-close
cleanup all source the env id from useEnvironmentId() / store and pass
it to createUserShell/stopUserShell. Shell-mode passthrough terminal
no longer blocks on session id — env id is sufficient. SSR resolves
the active session's task_environment_id from the session list and
calls fetchTerminals with the env id.

* test(e2e): cover env-keyed terminal new-tab flows + WS payload guard

New spec exercises the right-panel "+" button and the dockview "+ →
Terminal" menu, asserts the new tab connects, and intercepts outgoing
user_shell.create WS frames to verify the payload carries
task_environment_id and never session_id. A heal-coverage assertion
checks every listed session has task_environment_id populated post-boot.

* fix(e2e): drop right-panel '+' test, dockview is the only '+' path on desktop

The mobile TaskRightPanel SessionTabs aren't rendered at desktop
viewports — the dockview '+' menu is the sole new-tab affordance, so
testing the mobile path on chromium just timed out clicking a button
that never mounted. Consolidate into a single dockview '+ → Terminal'
test that asserts the new panel gets the backend-assigned 'Terminal 2'
label (proving env-shared shell list) plus the WS-payload regression guard.

* fix(e2e): assert dockview terminal-tab count, not 'Terminal 2' label

Dockview hardcodes the panel title to 'Terminal' for every tab — only
the mobile right-panel SessionTabs surface the backend's 'Terminal N'
label. Switch the assertion to count tabs to keep the e2e green.

* test(backend): cover SQL NULL branch of healSessionTaskEnvironmentIDs

Adds insertSessionWithNullEnvID and TestHealSessionTaskEnvironmentIDs_LinksNullOrphans
so the WHERE-clause IS NULL predicate is exercised — the existing tests only
seeded empty-string FKs. Also adds LIMIT 1 to the heal subquery as a
defensive measure: the unique index already guarantees ≤1 row per task at
runtime, but the SQL now reads as deterministic in isolation.

* refactor(web): drop dead taskGateOk on agent terminal WS gate

Agent passthrough routes by sessionId, not taskId — taskId was only used
for logging. Gating the WS effect on taskId forced agent terminals to
wait for useSession() to hydrate, adding a refresh-race window that
didn't guard any real precondition. connectionKey + canConnect already
cover the meaningful preconditions.

* fix(web): stamp env id on terminal panels for accurate cleanup

addTerminalPanel now bakes environmentId into the panel's params at
creation time. The dockview-layout-setup onDidRemovePanel handler
prefers the stamped env over re-deriving from the active session, so
closing a terminal that was opened under a different task no longer
calls stopUserShell with the wrong env (which silently no-ops on the
backend and leaks the shell process until session teardown). Falls back
to the active session's env for legacy panels persisted before the
param existed.

* fix(web): keep task id logging out of terminal reconnect deps

Kandev

Manage and run tasks in parallel. Orchestrate agents. Review changes. Ship value.

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

    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.
