The European Backend for AI Applications
Complete backend-as-a-service for intelligent automation. Build AI-powered applications without infrastructure complexity—with European data sovereignty built-in.
Building AI Applications Shouldn't Mean Building Infrastructure
Your team needs to ship AI-powered features, but traditional approaches force impossible choices:
You need a complete backend that just works—built for European requirements.
Complete Backend. Fully Isolated. Built for Europe.
Sinas is the backend-as-a-service that handles everything from authentication to AI orchestration, so you can focus on building your application—not maintaining infrastructure.
European Sovereignty
EU-hosted infrastructure with GDPR and AI Act compliance built in. Each deployment is completely isolated. Deploy on our infrastructure, yours, or hybrid - your choice.
One Backend, Unlimited Apps
Build 10, 50, or 100+ applications on a single backend deployment. Authentication, databases, AI assistants, workflows, email, and document management—all included.
Deploy in Minutes
From concept to production in hours. Complete isolation per deployment with dedicated instances and databases. Scale from one deployment to hundreds.
Everything Your Applications Need
Authentication & Permissions
Passwordless login, API keys, and granular permissions. Multi-tenant ready with groups and hierarchical access control. Built for organizations and agencies.
AI Assistants
Deploy conversational AI with any provider—OpenAI, Anthropic, or self-hosted models. Configure tools, memory, and context per assistant. Switch providers anytime.
Semantic Data Layer
Connect to existing databases or use managed storage. Three modes: query external sources, sync periodically, or fully managed. Auto-generated CRUD APIs.
Workflow Automation
Serverless Python functions with automatic execution tracking. Create webhooks, schedule jobs, chain workflows. Visual execution trees for debugging.
Document Management
Store and organize documents with AI-powered tagging and search. Automatic descriptions and categorization. Perfect for knowledge bases.
Email Infrastructure
Send and receive emails with templates and automation. Inbound webhooks trigger workflows. Track delivery and manage support inboxes—all built-in.
Context & Memory
Semantic context store for AI assistants. Organize knowledge by namespace, inject relevant information automatically. Your AI remembers what matters.
Management Console
Intuitive interface for managing your entire backend. Configure assistants, view logs, manage users, monitor workflows—no API calls needed.
Complete APIs
RESTful APIs for everything. OpenAPI documentation, webhook integrations, and real-time capabilities. Build however you want.
One Deployment = Complete Isolated Backend
Each Sinas deployment is a fully isolated instance with dedicated databases and infrastructure. Perfect for building multiple applications while maintaining sovereignty boundaries.
Complete Isolation
- Separate database instances (not schemas)
- Independent file storage
- Isolated network namespaces
- No shared resources between deployments
Build Unlimited Applications
- One deployment powers 10, 50, or 100+ apps
- Use groups to organize teams, clients, or projects
- All apps share the backend infrastructure
- Scale resources as your needs grow
Built for Real Applications
Customer Support Automation
Build intelligent support systems that understand context, access your knowledge base, and escalate intelligently. Handle email, chat, and API requests. Auto-tag tickets and provide instant answers.
Internal AI Tools
Give your team AI assistants that understand your business. Connect to internal databases, documentation, and systems. Role-based access ensures security. Deploy in hours, not months.
Multi-Tenant SaaS Applications
Built-in groups and permissions make multi-tenancy simple. Each customer gets isolated data, their own AI assistants, and custom configurations. Scale to thousands of tenants.
Document Intelligence Platforms
Ingest documents from any source, extract structured data, automatically classify and enrich. AI-powered search and tagging included. Perfect for legal tech, HR, and compliance.
Smart Workflow Automation
Receive webhooks, execute complex business logic, trigger AI analysis, coordinate responses. Visual execution tracking shows exactly what happened. Schedule anything from hourly to annually.
Client Delivery (Consultancies)
Deploy isolated backends for each client. Build 5-20 applications per client on their dedicated deployment. Complete data sovereignty and clean IP boundaries. Easy handoff when projects end.

Trusted by European Organizations
"We evaluated building our own backend versus using Sinas. Sinas saved us 6 months of development and ongoing maintenance costs. The EU hosting and compliance features sealed the deal."
"We deploy one Sinas instance per client. Complete isolation, easy handoff, and we get volume discounts. Our clients love that their data stays completely separate."
"The management console makes AI orchestration accessible to our entire product team, not just senior engineers. We can iterate much faster now."
"GDPR compliance was critical for our government contracts. Sinas's EU infrastructure and audit capabilities gave us everything we needed out of the box."
Frequently Asked Questions
What exactly is a "deployment"?
A deployment is a complete, isolated Sinas instance with dedicated PostgreSQL, MongoDB, and Redis databases. Each deployment can power unlimited applications and is completely separate from other deployments.
How many applications can I build on one deployment?
Unlimited. One deployment can power 10, 100, or 1,000+ applications. Use groups and permissions to organize access. The limit is your usage (storage, executions, etc.), not the number of apps.
When do I need multiple deployments?
Most organizations need 1-3 deployments (production, staging, dev). You need additional deployments for: geographic isolation (EU + US), compliance boundaries (regulated vs. non-regulated data), client isolation (consultancies), or business unit separation.
Can I use my own AI models?
Absolutely. Connect to OpenAI, Anthropic, self-hosted models via Ollama, or any OpenAI-compatible API. Switch providers per assistant or per request. No vendor lock-in.
Is Sinas GDPR compliant?
Yes. Sinas is built with GDPR as a core requirement. EU hosting, data minimization, purpose limitation, audit logging, and right to deletion are all built-in.
What about EU AI Act compliance?
Sinas provides technical measures required by the AI Act: audit logging, execution transparency, human oversight capabilities, risk documentation tools, and explainability features. We provide compliance documentation to help with your assessments.
How does managed on-premises work?
We deploy and manage Sinas on your infrastructure (your data center or cloud account). You control the physical location and network, we handle installation, updates, monitoring, and support. Best of both worlds for compliance.
What happens to my data if I stop using the service?
You can export everything—database contents, configurations, AI conversations, documents. Or switch to self-hosting the open source version. Your data is always yours.
