Ocsigen Server review
A focused Linux web server for OCaml teams building with Eliom.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ocsigen Server is an open-source web server implemented in OCaml. It is intended to serve web applications and content, with a clear fit for teams building applications in the OCaml ecosystem. Its positioning is especially relevant to developers using Eliom, the Ocsigen web application framework, because the server is designed to work alongside it. The product is distributed as software for self-hosted use rather than as a hosted subscription service.
The pricing model is straightforward: Ocsigen Server is open source and has a free plan, with no paid tiers described. That makes it suitable for small and mid-market teams that want to run the server themselves without a recurring software subscription. Its strongest ecosystem connection is Eliom, so teams already adopting that framework have a direct reason to consider Ocsigen Server. The combination of OCaml implementation and Eliom compatibility gives it a specific role rather than a general-purpose, multi-language positioning.
Deployment is Linux-based and self-hosted, which puts installation, configuration, and ongoing administration with the adopting team. This model can suit organizations that want control over their server environment, but it is less appropriate for buyers seeking a managed web-serving service. Ocsigen Server is best suited to OCaml teams using Eliom who are comfortable operating Linux software directly. Teams looking for broad language coverage, a hosted offering, or a wider platform ecosystem should consider a different web server product.
