Squashed history of PR #4892 (pr-4784-fix). Makes spaces the primary navigation and working surface, on the "associations bind at creation time only" model. Model - Issue <-> space is the only enforced ownership (per-space numbering). Parent/child and project<->space associations only seed defaults at creation; cross-space/child and project-association validations are removed. - Moving an issue renumbers it and records the old identifier in issue_identifier_alias; API/CLI lookups and GitHub branch/PR auto-linking fall back to the alias, so old identifiers resolve forever. - Membership drives only the sidebar and personal defaults — never access. Anyone can configure any space's member set wholesale (PUT /api/spaces/{id}/members); saving an empty set archives the space behind a confirm. - Per-user space order (workspace_space_member.sort_order, fractional): drag-sorted sidebar, "my first space" is the personal issue-creation default; the workspace default space backs headless creation (agents/CLI/Slack) and system placement. Surfaces - Sidebar: joined-spaces section (drag reorder, row -> space page, per-group persisted collapse), Workspace group with a More menu, Settings demoted to a footer icon. - /space/:key/{issues,projects,autopilots,settings} — space surfaces reuse shared page components; a routed /space/new create page (replacing the earlier create-space modal), reserved key "NEW" so it can never collide with a real space's /space/:key detail page. - Issue detail moves to /issue/:id (identifier-first, Linear-style; old /issues/:id redirects); create dialogs lead with a required space pill. - Agent runtime brief now carries Space context (id/key/name) through the daemon claim -> TaskContextForEnv -> prompt pipeline, with a "## Space Context" section and --space on issue create/update in both brief renderers, matching Project's existing treatment. - zh-Hans: Space translated to 空间 across locales and conventions.zh.mdx. Fixes along the way - Cache membership judgment gains the space dimension + space_changed WS flag. - Silent skip on default-space lookup during invite acceptance is now a hard failure (no space-less members). - Backfilled space_id into ~28 raw-SQL Go test fixtures across internal/handler and cmd/server that predated migration 132's NOT NULL cutover. - Fixed a resolve-loop bug in the IssueDetail identifier wrapper (mount/ unmount cycle on resolution failure) and gave it its own loading skeleton instead of a blank screen while resolving. - reserved-slugs generator's stale hardcoded doc-comment example synced back to /create-space. Verification - go build ./..., go vet ./..., go test ./... all clean. - pnpm typecheck (core/views/web/desktop) clean. - packages/views: 162 files / 1656 tests passing. - pnpm generate:reserved-slugs produces no diff. Follow-ups tracked in docs/follow-ups/space-rollout.md. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

What is Multica?
Multica turns coding agents into real teammates. Assign issues to an agent like you'd assign to a colleague — they'll pick up the work, write code, report blockers, and update statuses autonomously.
No more copy-pasting prompts. No more babysitting runs. Your agents show up on the board, participate in conversations, and compound reusable skills over time. Think of it as open-source infrastructure for managed agents — vendor-neutral, self-hosted, and designed for human + AI teams. Works with Claude Code, Codex, CodeBuddy, GitHub Copilot CLI, OpenCode, OpenClaw, Hermes, Pi, Cursor Agent, Kimi, Kiro CLI, Antigravity, Qoder CLI, and Trae CLI.
For larger teams, Squads add a stable routing layer: assign work to a group led by an agent, and the leader delegates to the right member.
Why "Multica"?
Multica — Multiplexed Information and Computing Agent.
The name is a nod to Multics, the pioneering operating system of the 1960s that introduced time-sharing — letting multiple users share a single machine as if each had it to themselves. Unix was born as a deliberate simplification of Multics: one user, one task, one elegant philosophy.
We think the same inflection is happening again. For decades, software teams have been single-threaded — one engineer, one task, one context switch at a time. AI agents change that equation. Multica brings time-sharing back, but for an era where the "users" multiplexing the system are both humans and autonomous agents.
In Multica, agents are first-class teammates. They get assigned issues, report progress, raise blockers, and ship code — just like their human colleagues. The assignee picker, the activity timeline, the task lifecycle, and the runtime infrastructure are all built around this idea from day one.
Like Multics before it, the bet is on multiplexing: a small team shouldn't feel small. With the right system, two engineers and a fleet of agents can move like twenty.
Features
Multica manages the full agent lifecycle: from task assignment to execution monitoring to skill reuse.
- Agents as Teammates — assign to an agent like you'd assign to a colleague. They have profiles, show up on the board, post comments, create issues, and report blockers proactively.
- Squads — group agents (and humans) under a leader agent and assign work to the squad. The leader decides who should pick it up, so routing stays stable as the team grows.
@FrontendTeaminstead of@alice-or-bob-or-carol. - Autonomous Execution — set it and forget it. Full task lifecycle management (enqueue, claim, start, complete/fail) with real-time progress streaming via WebSocket.
- Autopilots — schedule recurring work for agents. Cron triggers, webhooks, or manual runs — each autopilot creates the issue and routes it to an agent automatically, so daily standups, weekly reports, and periodic audits run themselves.
- Reusable Skills — every solution becomes a reusable skill for the whole team. Deployments, migrations, code reviews — skills compound your team's capabilities over time.
- Unified Runtimes — one dashboard for all your compute. Local daemons and cloud runtimes, auto-detection of available CLIs, real-time monitoring.
- Multi-Workspace — organize work across teams with workspace-level isolation. Each workspace has its own agents, issues, and settings.
Quick Install
macOS / Linux (Homebrew - recommended)
brew install multica-ai/tap/multica
Use brew upgrade multica-ai/tap/multica to keep the CLI current.
macOS / Linux (install script)
curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash
Use this if Homebrew is not available. The script installs the Multica CLI on macOS and Linux by using Homebrew when it is on PATH, otherwise it downloads the binary directly.
Windows (PowerShell)
irm https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.ps1 | iex
Then configure, authenticate, and start the daemon in one command:
multica setup # Connect to Multica Cloud, log in, start daemon
Self-hosting? Add
--with-serverto deploy a full Multica server on your machine:curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash -s -- --with-server multica setup self-hostThis pulls the official Multica images from GHCR (latest stable by default). Requires Docker. See the Self-Hosting Guide for details. If the selected GHCR tag has not been published yet, fall back to
make selfhost-buildfrom a checkout.
Getting Started
1. Set up and start the daemon
multica setup # Configure, authenticate, and start the daemon
The daemon runs in the background and auto-detects agent CLIs (claude, codex, codebuddy, copilot, opencode, openclaw, hermes, pi, cursor-agent, kimi, kiro-cli, agy, qodercli, traecli) on your PATH.
2. Verify your runtime
Open your workspace in the Multica web app. Navigate to Settings → Runtimes — you should see your machine listed as an active Runtime.
What is a Runtime? A Runtime is a compute environment that can execute agent tasks. It can be your local machine (via the daemon) or a cloud instance. Each runtime reports which agent CLIs are available, so Multica knows where to route work.
3. Create an agent
Go to Settings → Agents and click New Agent. Pick the runtime you just connected and choose a provider (Claude Code, Codex, CodeBuddy, GitHub Copilot CLI, OpenCode, OpenClaw, Hermes, Pi, Cursor Agent, Kimi, Kiro CLI, Antigravity, Qoder CLI, or Trae CLI). Give your agent a name — this is how it will appear on the board, in comments, and in assignments.
4. Assign your first task
Create an issue from the board (or via multica issue create), then assign it to your new agent. The agent will automatically pick up the task, execute it on your runtime, and report progress — just like a human teammate.
