Add the ability to launch parallel devenv instances (#9906)
* 🐳 Split devenv compose for parallel workspaces

Move shared services into an infra compose file and keep the main devenv container plus Valkey in a separate compose file driven by defaults.env. Parameterize host-side ports, container names, source path, and runtime env while keeping container-internal ports fixed for same-origin proxying.

Make tmux startup idempotent, add attach-devenv for the live instance, move shared MinIO user setup to infra startup, and let exporter scripts load backend _env.local overrides.

* 🐳 Run parallel devenv instances against shared infra

Add support for running N parallel devenv instances under separate compose
projects sharing Postgres, MinIO, mailer, and LDAP. Each instance has its
own main container, Valkey, source checkout, tmux session, and host port
range offset by 10000 (3449 -> 13449 -> 23449, etc.).

./manage.sh run-devenv-agentic --n-instances N reconciles the running set
to exactly {ws0..ws(N-1)}: missing instances are created (workspace sync
from the live repo via git ls-files + per-instance env-file generation
under docker/devenv/instances/ + detached tmux startup), surplus instances
are stopped highest-first via compose down (never -v), already-running
instances are left untouched. ws0 binds the live repo at PWD; ws1+ are
scratch clones under ~/.penpot/penpot_workspaces/.

Backend workers (enable-backend-worker) are gated on PENPOT_BACKEND_WORKER
in backend/scripts/_env; ws1+ overlays disable them so async-task
notifications stay bound to a single Valkey Pub/Sub instance.

Compose helpers wrap docker compose with env -i so per-instance overlay
--env-file actually overrides defaults.env -- without the strip, the shell
env from sourcing defaults.env at startup would shadow the overlay (Compose
gives shell precedence over --env-file).

Other:
- Drop network aliases (- main, - redis); use container_name for
  cross-container DNS so multiple instances on the shared network don't
  fight over the same DNS name.
- Pin volume names via name: (PENPOT_*_VOLUME) so volumes survive project
  renames; ws0 keeps the pre-existing physical names (penpotdev_*).
- Remove cross-project depends_on from main.yml (postgres/minio-setup now
  live in penpotdev-infra); manage.sh ensure-infra-up docker-waits on the
  minio-setup one-shot.
- Strict arg parsing in run-devenv / run-devenv-agentic; --n-instances 0
  rejected.
- Remove unused Host-matched server block from the Caddyfile.

Memory mem:devenv/core and developer docs updated.

*  Document and stabilise the parallel-workspace CLI; wire AI agents

Improve parallel-workspaces developer CLI,
and add an opt-in layer that lets four AI
coding agents (Claude Code, opencode, VS Code Copilot, OpenAI Codex CLI)
drive a specific workspace through a single launcher command.

Parallel-workspace semantics
----------------------------

each run-devenv-agentic call brings up one wsN;
--ws N (integer; default 0) targets a specific workspace and auto-starts
ws0 first when N>=1 so the worker invariant holds. --sync is forbidden on
ws0 and re-seeds the workspace from the live repo for ws1+. Stop semantics
mirror the start invariant -- ws0 is the last to stop, shared infra stops
with it, --all walks every instance highest-first. The worker policy
section explains why workers run only on ws0 (Postgres FOR UPDATE
SKIP LOCKED is safe across many workers but the cron dedup primitive is
best-effort, and :telemetry / :audit-log-archive are not idempotent).
Per-instance Valkey Pub/Sub isolation, msgbus topology, and the
"async task notifications miss ws1+ tabs" caveat are stated explicitly.

The mem:prod-infra/core memory captures the same external-services and
task-queue / Pub-Sub topology in agent-readable form, and
mem:backend/core and mem:critical-info now cross-link it so backend work
surfaces the horizontal-scaling constraints from the start.

AI coding agent integration
---------------------------

New top-level .devenv/ directory holds committed templates
(templates/{claude-code,opencode,vscode}.json and templates/codex.toml,
each with \${PENPOT_MCP_PORT} and \${SERENA_MCP_PORT} placeholders) plus
committed shared entries (matching shared/* files for Playwright, the
only workspace-independent server we ship today).

./manage.sh start-coding-agent <claude|opencode|vscode|codex> [--ws N]
launches the chosen client against one workspace. It cd's into the
target's directory (the live repo for ws0; workspace-path "wsN" for ws1+)
and refuses to launch unless (a) the binary is on PATH, (b) the
workspace directory exists for ws1+, and (c) the instance is up
(devenv-main-running) -- the MCP servers only exist while the devenv is
running. The agentic-devenv guide is restructured around this Quick
start path, with a per-client table and a Manual configuration fallback
for clients we don't cover.

Penpot video

Penpot is the open-source design platform for teams that build digital products at scale.

Penpots key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.

Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.

Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.

The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.

With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.

Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.

If your organization is scaling and needs extra support, were here to help. Talk to us
