* fix: address SSRF and token-leakage security vulnerabilities
- Azure TTS SSRF: validate region against /^[a-z][a-z0-9-]{1,30}[a-z0-9]$/
in both the contract (tts.ts) and runtime guard in synthesizeWithAzure,
preventing user-supplied region from redirecting requests to arbitrary hosts
- HubSpot token in logs: remove fullResponse from logger.info call;
log only non-sensitive metadata (hub_id, hub_domain, user_id) instead
of the full introspection response which included the access token
- Wealthbox account takeover: replace hardcoded email with per-user identity
by fetching /v1/users/me; fall back to token-derived stable identifier
so distinct Wealthbox users no longer share the same email address
- Shopify SSRF: apply shopifyShopDomainSchema (.myshopify.com allowlist)
to shopDomain from cookie before using it to build the fetch URL
* fix(wealthbox): correct getUserInfo endpoint, auth header, and stable identity
- Bug 1: Change API endpoint from /v1/users/me to /v1/me (correct Wealthbox API path)
- Bug 2: Replace ACCESS_TOKEN header with Authorization: Bearer <token> (standard OAuth 2.0)
- Bug 3: Remove generateId() from returned id (was non-deterministic, caused duplicate accounts);
use refresh token (stable, long-lived) instead of access token (rotates every ~2 hours)
as the hash source for the fallback identity; return null if no token is available
* fix(security): hash wealthbox fallback token identity, guard undefined userId
- Replace base64 encoding with SHA-256 hash for fallback token-derived identity
so raw token bytes are never stored in the DB
- Return null early when Wealthbox API response lacks an id field to prevent
all such users colliding on the wealthbox-undefined account
* fix(auth): replace stale wealthbox userInfoUrl placeholder with actual endpoint
The dummy URL comment was rendered obsolete when getUserInfo was updated
to fetch from api.crmworkspace.com/v1/me. Align userInfoUrl with the real
endpoint used in the getUserInfo implementation.
* fix(auth): append generateId() suffix to Wealthbox account IDs to match codebase pattern
All other providers use `${stableId}-${generateId()}` so the account.create.after
hook can strip the UUID suffix, find stale sibling rows, and migrate credential FKs.
Without the suffix the migration logic is skipped and reconnections would hit
duplicate key conflicts instead of gracefully updating credentials.

Quickstart
Cloud-hosted: sim.ai
Self-hosted: NPM Package
npx simstudio
Note
Docker must be installed and running on your machine.
Options
| Flag | Description |
|---|---|
-p, --port <port> |
Port to run Sim on (default 3000) |
--no-pull |
Skip pulling latest Docker images |
Self-hosted: Docker Compose
git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d
Sim also supports local models via Ollama and vLLM — see the Docker self-hosting docs for setup details.
Self-hosted: Manual Setup
Requirements: Bun, Node.js v20+, PostgreSQL 12+ with pgvector
- Clone and install:
git clone https://github.com/simstudioai/sim.git
cd sim
bun install
bun run prepare # Set up pre-commit hooks
- Set up PostgreSQL with pgvector:
docker run --name simstudio-db -e POSTGRES_PASSWORD=your_password -e POSTGRES_DB=simstudio -p 5432:5432 -d pgvector/pgvector:pg17
Or install manually via the pgvector guide.
- Configure environment:
cp apps/sim/.env.example apps/sim/.env
# Create your secrets
perl -i -pe "s/your_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_internal_api_secret/$(openssl rand -hex 32)/" apps/sim/.env
perl -i -pe "s/your_api_encryption_key/$(openssl rand -hex 32)/" apps/sim/.env
# DB configs for migration
cp packages/db/.env.example packages/db/.env
# Edit both .env files to set DATABASE_URL="postgresql://postgres:your_password@localhost:5432/simstudio"
- Run migrations:
cd packages/db && bun run db:migrate
- Start development servers:
bun run dev:full # Starts Next.js app and realtime socket server
Or run separately: bun run dev (Next.js) and cd apps/sim && bun run dev:sockets (realtime).
Copilot API Keys
Copilot is a Sim-managed service. To use Copilot on a self-hosted instance:
- Go to https://sim.ai → Settings → Copilot and generate a Copilot API key
- Set
COPILOT_API_KEYenvironment variable in your self-hosted apps/sim/.env file to that value
Environment Variables
See the environment variables reference for the full list, or apps/sim/.env.example for defaults.
