Apache Tomcat

Apache Tomcat is an open-source implementation of the Jakarta Servlet, Jakarta Server Pages, and other Jakarta EE technologies, providing a pure Java HTTP web server environment for running Java code. The Tomcat Manager application exposes an HTTP API for deploying, managing, and monitoring web applications. The JMX Proxy Servlet provides programmatic access to JMX MBeans for server diagnostics and configuration. Governed by the Apache Software Foundation.

Apache Tomcat publishes 8 API contracts indexed on the APIs.io network, including Applications API, Configuration API, Diagnostics API, and 5 more. Tagged areas include Application Server, Java, Servlet Container, Web Server, and Open Source.

The Apache Tomcat catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Apache Tomcat’s developer surface includes authentication, documentation, changelog, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
