OPEN SOURCE · BUILDING IN PUBLIC

The infrastructure
where your AI flows
through.

Cauce is the European open source platform to build, deploy and scale robust AI agents. No vendor lock-in. No vaporware. Built to last.

WHY CAUCE EXISTS

There is too much
vaporware
in AI.

💸

Demos that never reach production

80% of AI agent projects you see on LinkedIn are prototypes nobody uses in production. Code without tests, without multi-tenancy, without observability.

🔒

Vendor lock-in disguised as ease

SaaS agent platforms charge you per message, tie you to their LLM, and pivot when it suits them. Your business cannot depend on that.

🧩

Integrations that do not scale

WhatsApp on one side, Telegram on another, your own API in a third repo. Each channel with its own duplicated business logic. A maintenance nightmare.

🕳️

No European reference infrastructure

Everything serious comes from the US, with prices in dollars, servers in us-east-1, and no thought for GDPR. Europe needs its own infrastructure.

Cauce exists because the industry has been optimising for the demo, not for production, for far too long.

It is time to build something that actually holds up.

WHAT IS CAUCE

Real infrastructure.
No demos.

A modular platform that connects your channels, manages your agents memory, and exposes everything through an API. Built on Spring Boot, designed for consulting firms delivering real projects to real clients.

🌊

Multichannel from day one

WhatsApp, Telegram, voice and web chat in a single runtime. No duplicated business logic. No maintaining four separate integrations. The cauce receives every flow.

🧠

Persistent memory and context

Agents remember. Memory per conversation, per user, per tenant. Support for multiple swappable LLMs without touching the agent code.

cauce-memory
🏗️

Multi-tenant and observable

Designed for a single instance to serve many clients. Metrics, traces and logs built in. Each tenant isolated from the architecture, not as an afterthought.

BUILDING IN PUBLIC

Built
in the open.

01

A single developer, from Spain. No funding rounds, no 20-person team, no office in Madrid. Just consistent code and honest work.

02

The whole process, in public. Every technical decision, every mistake, every refactor. If something does not work, I say so. If something works well, also.

03

The code is the documentation. No empty marketing. If you want to know whether Cauce is serious, open the repo, read the code, draw your own conclusions.

04

Europe needs its own infrastructure. GDPR, EU-based servers, Spanish as a first-class language. We are not an American fork with a European flag.

DEVLOG #4 · IN PROGRESS

Working on first channel integration. Web Chat → cauce-core prototype. WhatsApp and memory layer next.

DEVLOG #3 · DECISION

Decision: 10 modules in settings.gradle.kts. Easier to split when it hurts than to unify when everything is already separate.

DEVLOG #1 · KICKOFF

This starts. Too many AI projects never reach production. Cauce is going to be different.

Be the first to
try Cauce.

We are building in the open. When we ship the first public version, the list will get access first.

No spam. Only when there is something worth it.
