Every AI feature comes with work nobody sees
AI projects tend to start with weeks of groundwork: logins, access rules, logging and somewhere safe to run code. It never appears on a brief, yet every team builds it again from scratch. Then the feature finally works, legal and security ask where the data goes, and that’s where projects stall.
Sinas (beta) takes care of both. The groundwork is ready from day one, and you decide which model provider sees your data, if any.
What you get out of the box
One platform for the parts every AI application needs.
Any model: Choose a provider for each agent, or run a model on your own hardware.
Automation: Agents run code, follow schedules and connect to the tools you already use.
Your data stays put: Agents query your existing databases and files where they already are.
Governance: Access rules, full logging and a configuration you can export at any time.
Build it, rent it, or start from Sinas
Most teams weigh up two options before they find Sinas. Here is how they compare.
| Build it yourself | Closed AI platforms | Sinas | |
| Time to first feature | Weeks spent on auth, permissions, logging and queues first | Fast to start | Minutes on Cloud; the infrastructure is already there |
| Where your data goes | Your choice, if you build it | Governed by the vendor’s terms | Your instance, your model provider, or no third party at all |
| Model choice | Anything you integrate | Usually limited to what the vendor supports | OpenAI, Anthropic, Mistral or a local model, set per agent |
| Permissions and audit trail | Yours to design and maintain | Varies by vendor | Checked on every call, every request logged |
| Leaving | Nothing to leave | Often means rebuilding | Export your configuration and self-host the same code |
| Cost | Development time, then maintenance | Subscription, often per user | Free to self-host; Cloud from €49/month |
Built by the team that uses it every day
Sinas started inside WeAreBrain’s client work. Every AI project we delivered needed the same foundations, so we built them once and made them open source. Today, we build client applications on Sinas ourselves, from regulated healthcare environments to international consumer brands.
