What Adoptium does
Adoptium is an open-source Working Group hosted by the Eclipse Foundation that produces Eclipse Temurin, a vendor-neutral, prebuilt distribution of OpenJDK binaries. The Working Group was established in March 2021 following the migration of the prior AdoptOpenJDK community project, and is governed through Eclipse Foundation processes with named strategic members including Microsoft, Red Hat, and Alibaba Cloud. Its primary product, Eclipse Temurin, delivers Java SE TCK-certified and AQAvit-verified runtime binaries (JDK and JRE) across more than 35 platform combinations spanning Windows, macOS, Linux distributions, Alpine, AIX, and architectures including x64, ARM64/AArch64, ARM32, ppc64le, s390x, and RISC-V. Long Term Support releases (JDK 8, 11, 17, 21, 25) carry multi-year availability commitments, with Java 8 supported through December 2030 and Java 21 through December 2029. The portfolio also includes Eclipse AQAvit (the proprietary quality assurance test suite with automated reruns, change-based testing, and performance benchmarking) and Eclipse Mission Control (diagnostics and profiling tooling).
The business model is structurally non-commercial: Temurin binaries are distributed free of charge without usage restrictions, and the organization generates operating revenue through Eclipse Adoptium Working Group membership fees, the Sustainer Program for enterprise contributions, and donations channeled through the Eclipse Foundation. Commercial support, where needed by enterprises, is provided by third-party partners — IBM (IBM Runtimes for Business), Red Hat subscriptions, ManageCat, and Open Elements. Distribution is achieved through self-service channels including direct downloads from adoptium.net, package managers (Homebrew, SDKMAN, WinGet, apt, dnf/yum, zypper, apk), Docker Hub, the Adoptium REST API, and a setup-java GitHub Action. Customers include developers and large enterprises across financial services, automotive, telecommunications, consulting, and technology — among them Bloomberg, Microsoft, MongoDB, Atlassian, Mercedes-Benz Tech Innovation, Michelin, Societe Generale, T-Systems, Accenture, Red Hat, Dynatrace, Arm, MediaMarktSaturn, and Trend Micro — though all named logos reference use of the free runtime rather than paid contracts. The platform had surpassed 500 million cumulative downloads as of October 31, 2024, with 50% year-over-year download growth reported in May 2024 and contributions from more than 300 community contributors.

Adoptium competitors and assessment
Company assessmentDirect peers
- Azul Zulu: Azul's free OpenJDK builds (Zulu) and commercial Zulu Prime offering. Directly comparable to Temurin as a TCK-certified, multi-platform OpenJDK distribution, with Azul also offering commercial support that competes with IBM/Red Hat/ManageCat for Temurin support.
- SAP Machine: SAP's free OpenJDK distribution for SAP customers and the broader Java ecosystem. Comparable in offering TCK-certified builds, supporting multiple platforms, and providing free binaries; though smaller in scale than Temurin.
- Amazon Corretto: AWS's free, multi-platform OpenJDK distribution with long-term support and TCK certification. Direct competitor to Eclipse Temurin serving the same developer and enterprise Java runtime market, distributed via similar package managers and container registries.
- Microsoft Build of OpenJDK: Microsoft's free OpenJDK distribution. Despite Microsoft being an Adoptium Strategic Member, this represents a parallel Microsoft-branded distribution that overlaps directly with Temurin in features, platforms, and target enterprise customers.
- BellSoft Liberica JDK: BellSoft's free and commercial Liberica JDK distribution with strong container and cloud-native focus. Direct competitor in TCK-certified OpenJDK distribution, with overlapping Alpine, ARM, and container image offerings.
- IBM Semeru Runtime: IBM's free certified OpenJDK distribution with commercial support (IBM Runtimes for Business). Direct peer to Temurin; IBM is also an Adoptium commercial support partner, positioning it on both sides of the market.
- Alibaba Dragonwell: Alibaba's OpenJDK distribution optimized for large-scale e-commerce and cloud workloads in China. Direct peer with overlapping LTS, free distribution, and TCK certification; Alibaba Cloud is also an Adoptium Working Group member.
Broad incumbents
- Red Hat OpenJDK: Red Hat's OpenJDK distribution bundled with RHEL subscriptions. Red Hat is an Adoptium Working Group member and provides commercial Temurin support, giving it both direct and indirect roles in the same Java runtime ecosystem.
- Oracle JDK: The reference Java SE implementation and primary commercial JDK vendor. Competes with Temurin via paid licensing but is also the upstream source of all OpenJDK distributions including Temurin, making it both competitor and supplier.
Emerging players
- GraalVM: High-performance JDK distribution from Oracle with polyglot and native-image capabilities. Emerging alternative to traditional JVM runtimes; while Temurin itself includes some GraalVM-aligned features (AOT, JEP 483/484), GraalVM represents a potential long-term substitution risk for traditional Java runtimes.
