What is a CMP?
A Consent Management Platform is the consent manager: the tool that organizes user preferences about their cookies and tracking data in a transparent way.

transparency.
Like a granary (hórreo) raised above the ground, Esbilla CMP isolates data from unwanted trackers. Ethical governance for your digital harvest.
The pillars of Esbilla
Open Source Andecha
Open source software means anyone can inspect and improve the tool. We build together so security becomes a common good.
Governance and GDPR
Complying with the General Data Protection Regulation (GDPR) is not just a legal obligation; it's the structural skeleton that ensures your website respects the digital dignity of visitors.
Technical Manifesto: The Data Granary (Docker-First)
This document is the answer to the lack of a technical and self-hosted solution for managing user data.
On-Premise Sovereignty
Esbilla CMP is born to be open source and offer the possibility of being self-hosted via Docker, eliminating opacity in data handling.
"Andecha" Audit
Being open source, the system is not a black box; any technician can inspect the contents to ensure there are no leaks.
2026 Efficiency
We leverage AI capabilities to create and maintain a lightweight, powerful core that is easy to deploy with a simple docker run.
Ethical Governance
We don't just manage banners; we structurally separate necessary cookies from marketing ones, returning control to the machine owner.
Reasonable Cost
We break excessive subscription models, offering a professional tool at a reasonable cost for companies that value their independence.
Technical Sovereignty vs. Dependency
Esbilla is designed for those who want physical control of their data, not just a colorful banner.

From Sevares to the World: Why build a digital hórreo?
I am Jorge Luis Álvarez Solís (Jlasolis). Son of Jorge and Pili, grandson of Ángel, Marina, Zulema, and Marcelino. I was born and raised in Sevares, where I learned that things that last are built on solid foundations and through community.
Many of you might wonder what a programmer—trained at Seresco and in the cafeteria of the Faculty of Computer Science—is doing in this web privacy "mess." Life has led me through many trades, always with an entrepreneurial spirit, but Open Source has always been a special part, a "stone soup": that recipe where everyone contributes what they have so that, in the end, we all eat.
What is "Esbillar" the web?
For those not familiar with the term, a CMP (Consent Management Platform) is the tool that manages cookies. But I prefer to explain it as we do in Asturias: when you "esbillar," you separate the ear of corn from the leaves. A CMP does the same with your browsing data: it separates the cookies necessary for the web to function from those used for statistics or marketing, leaving only those you truly accept.
The moment is now (and AI is to blame)
It is 2026. Current CMP pricing models are, frankly, a robbery. They charge exorbitant amounts for a solution that, technically, is not an insurmountable challenge. With the power and ease that AI gives us today, there is no excuse: it is the perfect time for a reasonable alternative. We started with many resources made by AI but with the intention that, as a community, we humanize this common project.
Why Open Source and Self-Managed?

Andecha and Sestaferia: Having Esbilla CMP be open source means people can help improve it collectively. It's the spirit of sestaferia or working in andecha: if we fix the road together, we all travel better.

Your Granary, Your Rules: Data sovereignty means that instead of storing in a multinational's giant warehouse, you store and manage your information on your own machine. Like that hórreo that protects the grain from moisture and pests, Esbilla lets you set up the system in Docker to isolate your data from unwanted trackers. We also use the classic Open Source formula "Give away the recipe, open a restaurant" by offering SaaS services so anyone without technical knowledge can use our Cookie manager or by offering our services to set up the system on your infrastructure.
This is not just software; it's returning clean air and transparency to our digital harvest.
