Set Up Sentry Development Environment

Walk the user through getting Sentry running locally. The full process from a bare machine takes 30-45 minutes — most of that is downloading dependencies and Docker images. Set expectations clearly at each step.

AL MCP: If the al MCP server is available, use al_search_docs and al_read_doc for detailed troubleshooting. The AL docs cover devenv, devservices, and common issues in depth. The AL server is part of the devinfra-mcp project — see that repo for setup instructions if the server isn't configured yet. The SSE endpoint is configured in .pi/mcp.json (pi) or .mcp.json / .cursor/mcp.json (Claude Code / Cursor).

Step 1: Detect Current State

Before doing anything, assess what's already installed. Run all of these:

# Check OS
uname -s && uname -m

# Check shell
echo $SHELL

# Check if devenv exists
which devenv 2>/dev/null || ls ~/.local/share/sentry-devenv/bin/devenv 2>/dev/null

# Check devenv version (outdated versions cause failures)
devenv --version 2>/dev/null || ~/.local/share/sentry-devenv/bin/devenv --version 2>/dev/null

# Check Docker runtime
docker context ls 2>/dev/null
docker info --format '{{.Name}}' 2>/dev/null

# Check OrbStack
which orbctl 2>/dev/null && orbctl status 2>/dev/null

# Check Colima
which colima 2>/dev/null && colima status 2>/dev/null

# Check direnv
which direnv 2>/dev/null

# Check if repo is already set up
ls .venv/bin/sentry 2>/dev/null && ls node_modules/.bin 2>/dev/null

Based on results, skip to the appropriate step. If everything is installed, jump to Step 6.

Step 2: Install Prerequisites (macOS)

Xcode Command Line Tools

xcode-select -p 2>/dev/null || xcode-select --install

If not installed, the user must complete the interactive install dialog (~10 min). Wait for it.

Homebrew

which brew || /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Docker Runtime — OrbStack or Colima

Ask the user which they prefer. Explain the tradeoffs:

If choosing OrbStack:

brew install --cask orbstack

Then start OrbStack from Applications. Verify: docker info

If choosing Colima: Colima gets installed by devenv bootstrap — no separate step needed.

Important: Do NOT run Docker Desktop alongside either runtime — it causes conflicts.

Step 3: Install devenv

# For external (non-Sentry-employee) contributors:
# export SENTRY_EXTERNAL_CONTRIBUTOR=1

curl -fsSL https://raw.githubusercontent.com/getsentry/devenv/main/install-devenv.sh | bash

This installs to ~/.local/share/sentry-devenv/bin/devenv.

Shell Configuration

The user's shell MUST have devenv on PATH and direnv hooked in. Check and fix:

# Check if already configured
grep -q "sentry-devenv" ~/.zshrc 2>/dev/null || grep -q "sentry-devenv" ~/.bashrc 2>/dev/null

If not configured, add to the appropriate shell config (~/.zshrc for zsh, ~/.bashrc for bash):

# devenv
export PATH="$HOME/.local/share/sentry-devenv/bin:$PATH"

# direnv
eval "$(direnv hook zsh)"   # or: eval "$(direnv hook bash)"

Tell the user to restart their terminal (or source ~/.zshrc) after this change.

Verify devenv Version

Minimum version changes frequently. If devenv is already installed, check it's not outdated:

devenv --version

If the version is old (e.g., < 1.22), upgrade:

devenv update

If devenv update itself fails because the version is too old, reinstall:

curl -fsSL https://raw.githubusercontent.com/getsentry/devenv/main/install-devenv.sh | bash

Step 4: Bootstrap (First Time Only)

For a completely fresh setup, run bootstrap first:

devenv bootstrap

This is interactive (~5 min) — it prompts for SSH keys, coderoot directory, etc. It installs Homebrew, Colima, Docker CLI, and direnv.

After bootstrap completes, close and reopen the terminal.

Step 5: Sync the Environment

This is the longest step. Tell the user:

This will take 10-20 minutes on first run. It installs Python, Node, all pip/npm dependencies, and runs database migrations. Subsequent syncs are much faster (2-5 min).

If direnv hangs

The .envrc runs Docker checks. If the Docker runtime isn't running, direnv will hang. Symptoms:

direnv: ([...]/direnv export zsh) is taking a while to execute. Use CTRL-C to give up.

Fix: Start the Docker runtime first:

• OrbStack: Open OrbStack.app or open -a OrbStack
• Colima: devenv colima start

Then direnv allow again.

Chicken-and-Egg Problem

direnv checks node version and sentry installation. On a fresh setup, these don't exist yet, so direnv will fail. This is normal. Bypass direnv and run devenv sync directly:

~/.local/share/sentry-devenv/bin/devenv sync

Or if devenv is on PATH:

devenv sync

After sync completes, direnv allow should succeed.

If devenv sync fails

Common causes:

1. Outdated devenv — devenv update or reinstall
2. Docker not running — start OrbStack/Colima first
3. Network issues — retry; some downloads are large

Run devenv doctor for automated diagnosis.

Step 6: Start Services

First: Start Docker Images

devservices up

⏱️ First run: 5-10 minutes. It pulls many Docker images (PostgreSQL, Redis, Kafka, ClickHouse, Snuba, Relay, etc.). This is a one-time cost. Tell the user:

This is downloading all the Docker images Sentry needs. It looks like a lot — that's normal. Subsequent starts take ~30 seconds.

Subsequent runs: ~30 seconds.

OrbStack Socket Issue

If devservices up or devservices serve fails with:

Make sure colima is running. Run `devenv colima start`.

...but the user is using OrbStack, the devservices.py command is checking for the Colima socket only. Check src/sentry/runner/commands/devservices.py:

grep -n "colima\|docker.sock\|orbstack" src/sentry/runner/commands/devservices.py

The _find_docker_socket() function needs to check multiple socket paths. On macOS it should try, in order:

1. ~/.colima/default/docker.sock (Colima)
2. ~/.orbstack/run/docker.sock (OrbStack)
3. /var/run/docker.sock (Docker Desktop / default)

If only Colima is checked, patch it to support all runtimes. Read references/orbstack-fix.md for the exact pattern.

Then: Seed the Database

If this is a first-time setup, the database needs seeding:

.venv/bin/sentry upgrade --noinput

This runs all Django migrations AND creates default data (organizations, roles, projects). Without this, the dev server will 500 on every page.

Do NOT just run sentry django migrate — that only runs migrations without seeding the required default data.

Create Superuser

.venv/bin/sentry createuser --superuser --email admin@sentry.io --password admin --no-input

Step 7: Start the Dev Server

devservices serve

Or directly:

.venv/bin/sentry devserver

What to Expect on Startup

Kafka topic warnings are normal. On first start, you'll see many lines like:

[WARNING] sentry.batching-kafka-consumer: Topic 'taskworker' or its partitions are not ready, retrying...

These settle down after 30-60 seconds as Kafka auto-creates topics. Don't panic.

Access the Dev Server

• URL: http://dev.sentry.localhost:8000
• Login: admin@sentry.io / admin

Required: Sentry Cookie Sync Extension

Without this extension, the UI shows a blank white screen. Install it:

https://chromewebstore.google.com/detail/sentry-cookie-sync/kchlmkcdfohlmobgojmipoppgpedhijh

This syncs auth cookies between sentry.io and dev.sentry.localhost. It's not optional.

Day-to-Day Commands

After initial setup, the daily workflow is:

cd ~/Projects/sentry    # (or wherever the repo lives)
devservices up           # start background services (~30s)
devservices serve        # start dev server
# → http://dev.sentry.localhost:8000

After pulling new code:

devenv sync              # update dependencies + migrations (2-5 min)

Troubleshooting Decision Tree

For deeper troubleshooting, use the AL MCP if available (devinfra-mcp):
