* feat(integrations): add AWS SES, IAM Identity Center, and enhanced IAM/STS/CloudWatch/DynamoDB integrations - Add AWS SES v2 integration with 9 operations (send email, templated, bulk, templates, account) - Add AWS IAM Identity Center integration with 12 operations (account assignments, permission sets, users, groups) - Add 3 new IAM tools: list-attached-role-policies, list-attached-user-policies, simulate-principal-policy - Fix DynamoDB duplicate subBlock IDs, add operation-scoped field names, add subblock migrations - Add authMode: AuthMode.ApiKey to DynamoDB block - Fix CloudWatch routes: toError, client.destroy(), withRouteHandler, auth outside try - Fix STS/DynamoDB/IAM routes: nullable Zod schemas, withRouteHandler adoption - Fix Identity Center: list_instances pagination, list_groups instanceArn condition - Add subblock migrations for renamed DynamoDB fields (key, filterExpression, etc.) - Apply withRouteHandler to all new and existing AWS tool routes * docs(ses): add manual intro section to SES docs * fix(dynamodb): add legacy fallbacks in params for subblock migration compatibility Workflows saved with the old shared IDs (key, filterExpression, etc.) that migrate to get-scoped slots via subblock-migrations still work correctly on update/delete/scan/put operations via fallback lookups in tools.config.params. * feat(contact): add contact page, migrate help/demo forms to useMutation (#4242) * feat(contact): add contact page, migrate help/demo forms to useMutation * improvement(contact): address greptile review feedback - Map contact topic to help email type for accurate confirmation emails - Drop Zod schema details from 400 response on public /api/contact - Wire aria-describedby + aria-invalid in LandingField for both forms - Reset helpMutation on modal reopen to match demo-request pattern * improvement(landing): extract shared LandingField component * fix(landing): resolve error-page crash on invalid /models and /integrations routes (#4243) * fix(layout): use plain inline script for PublicEnvScript to set env before chunks eval on error pages * fix(landing): handle runtime env race on error-page renders React skips SSR on unhandled server errors and re-renders on the client (see vercel/next.js#63980, #82456). Root-layout scripts — including the runtime env script that populates window.__ENV — are inserted but not executed on that client re-render, so any client module that reads env at module evaluation crashes the render into a blank "Application error" overlay instead of rendering the styled 404. This replaces the earlier PublicEnvScript tweak with the architectural fix: - auth-client.ts: fall back to window.location.origin when getBaseUrl() throws on the client. Auth endpoints are same-origin, so this is the correct baseURL on the client. Server-side we still throw on genuine misconfig. - loading.tsx under /models/[provider], /models/[provider]/[model], and /integrations/[slug]: establishes a Suspense boundary below the root layout so a page-level notFound() no longer invalidates the layout's SSR output (the fix endorsed by Next.js maintainers in #63980). - layout.tsx: revert disableNextScript — the research showed this doesn't actually fix error-page renders. The real fix is above. * improvement(landing): use emcn Loader in scoped loading.tsx, trim auth-client comment Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> * fix(iam): correct MissingContextValues mapping in simulatePrincipalPolicy * fix(aws): add conditionExpression migration fallback for DynamoDB delete, fix SES pageSize min * fix(aws): deep validation fixes across SES, IAM, Identity Center, DynamoDB integrations - IAM: replace non-existent StatementId with SourcePolicyType in simulatePrincipalPolicy - IAM: add .int() constraint to list-users/roles/policies/groups Zod schemas - IAM: remove redundant manual requestId from all 21 IAM route handlers - SES: add .refine() body validation to create-template route - SES: make bulk email destination templateData optional, only include ReplacementEmailContent when present - SES: fix pageSize guard to if (pageSize != null) to correctly forward 0 - SES: add max(100) to list-templates pageSize, revert list-identities to min(0) per SDK - STS: fix logger.error calls to use structured metadata pattern - Identity Center: remove deprecated account.Status fallback, use account.State only - DynamoDB: convert empty interface extends to type aliases, remove redundant error field, fix barrel to absolute imports * regen docs * fix(iam): add .int() constraint to maxSessionDuration in create-role route * fix(ses): forward pageSize=0 correctly in listIdentities util * fix(aws): add gradient background to IdentityCenterIcon, fix listTemplates pageSize guard --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

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.
