Open source already powers the world's infrastructure. Let it power your data.
97% of the world's software already contains open source. We build your infrastructure on open standards proven at global scale: no licenses restricting your data, no lock-in, and within your jurisdiction.
You already build on open source. You just may not know it.
The proprietary software you use every day runs on open-source code underneath. It is not the risky option: it is the foundation everything else relies on. Open source already underpins proprietary software.
It is not a cost decision. It is a control decision.
With open standards, there are no licenses restricting access to your own information, no retention clauses, and no provider that can one day monetize what you created.
Your data, in an open format
Readable by any engine in the ecosystem. If you decide to change providers, your data remains there, in a format any other vendor can read. Exit costs approach zero, not as a sales claim but as an inherent property of the format.
Verifiable sovereignty
The CLOUD Act requires US-based providers to hand over data regardless of where it is stored. In June 2025, Microsoft France acknowledged under oath before the French Senate that it could not guarantee sovereignty even for data hosted in France.
Your data, without a toll
Your data is one of your company's most valuable assets. With open standards and your own infrastructure, no one can charge you to access what is already yours.
What open source gives you that proprietary software cannot.
Opening your infrastructure is not just about cost. It changes three issues that keep every CIO awake at night: continuity, trust, and the future.
It cannot be switched off
A vendor can discontinue its product and force a costly migration. Open-source code cannot be switched off: even if its sponsor disappears, the code remains yours and the community's. Business continuity is guaranteed.
Do not trust: verify
With proprietary software, you depend on a black box. With open-source code, you or a third party can audit exactly what it does: no hidden telemetry and no undisclosed access. Security is demonstrated, not promised.
AI is built in the open
The tooling that defines AI is open: PyTorch, data formats, and many of the models. Open source is not infrastructure's past; it is where the future of agents is being built.
The components, and who runs them in production.
Mature projects running in production at the world's most demanding organizations, together with OSL, the semantic layer developed by Opendome.
Apache Iceberg
The table format that organizes structured data. Created at Netflix (2017), it is now the de facto standard. Supported by AWS, Azure, Google, Snowflake, and Databricks.
Lance / LanceDB
It connects unstructured data, including documents, email, and transcripts, with everything else and enables the semantic search agents need. Up to 100× faster than Parquet for random access. Created by an original author of Pandas.
The semantic graph
It turns data into business knowledge: which entities exist, which attributes they have, and how they relate. OSL is Opendome's semantic layer: it compiles queries for Trino and retrieval for Lance under a single policy.
The rest of the stack is just as robust.
Every layer is built on equally proven projects, organized by what each one brings to your infrastructure.
Trino + Meltano/Singer: PostgreSQL, MySQL, and Salesforce included, plus purpose-built runners for files and documents. Trino: Netflix, Airbnb, LinkedIn, Salesforce.
LanceDB + unstructured, pdfminer, and specialized parsers, enabling tables and documents to coexist and relate to one another. LanceDB: Midjourney, Character.ai, Runway.
Opendome policy engine + SQLGlot: every query is compiled against subject, entity, row, and column policies. Developed and operated by Opendome.
opendome_audit + OpenLineage: hash chains and Merkle checkpoints for auditing; Prometheus, Grafana, Loki, and Tempo for observability. OpenLineage: an LF AI & Data project. Grafana Labs: professional support.
Kubernetes + CloudNativePG on S3-compatible storage. Kubernetes: BBVA, ING, Deutsche Bahn.
Network isolation with Cilium and image signing with cosign/Sigstore. Sigstore: Google, GitHub.
“What if something goes wrong? Who do I call?”
The most common objection. The answer: a mature market of thousands of companies provides support, implementation, and contractual guarantees for these exact components. Red Hat (IBM) built a multibillion-dollar business solely on open-source software support, and it is the provider Salesforce and SAP rely on.
Structural dependency
When prices rise, terms change, or a vendor decides to monetize access to your data, the only way out is a costly migration. The partner's business model structurally depends on deepening your reliance on the vendor.
Voluntary relationship
You choose your provider based on how well it integrates and operates these components, not because leaving is impossible. Since anyone can read and audit the same code, services compete on quality and price: more technical, less extractive.
Built on the technology that already supports the world's largest companies.
Opendome integrates these components into open-source, EU-first data infrastructure. Your data lives in an open format, in your cloud, and within your jurisdiction. No lock-in, no retention clauses, and no paying to access what is already yours.
