Core offering

BellSoft develops and distributes Liberica JDK, a TCK-verified, free open-source Java SE implementation that serves as an Oracle JDK drop-in replacement with enterprise-grade support. Around it the company bundles Alpaquita Linux (a Java-optimized Linux base), BellSoft Hardened Images (pre-hardened, near-zero CVE container images), and the Liberica Native Image Kit (GraalVM-based native compilation tooling), sold individually or as a unified Java runtime platform for cloud, container, and Kubernetes deployments.

Product overview

BellSoft offers a unified Java runtime platform built around Liberica JDK as the core product, complemented by Alpaquita Linux as an optimized OS layer, and Hardened Images as a security-focused container solution. The portfolio includes specialized flavors (Performance Edition, Lite for cloud, CRaC support, Embedded, legacy 6/7 support), tooling (Liberica Native Image Kit for GraalVM-based native compilation, Liberica Mission Control for monitoring), and various container image offerings (Alpaquita Containers, Spring Boot-optimized containers, Liberica JDK containers). The company positions itself as an Oracle JDK alternative trusted by enterprises, providing TCK-verified builds with cryptographic signing, 24/7 support, and security coverage across both OS and JDK layers.

Partnerships

One partnership is on record.

• Red HatcoreStrategic or Co-development Partner · 1 January 2026Red Hat launched Project Hummingbird in response to BellSoft's survey findings on container security. The project creates a catalog of minimal, hardened container images aimed at reducing attack surfaces and achieving 'zero-CVE' applications. BellSoft's research on pre-hardened images influenced this Red Hat initiative, demonstrating market education impact.

Direct peers

• Azul Systems: Direct commercial JDK competitor offering Zulu OpenJDK builds and Azul Platform Prime (high-performance JDK). Closest comparable to BellSoft in the commercial-JDK-support category, serving enterprise Java shops seeking Oracle JDK alternatives.
• Eclipse Adoptium (Temurin): Community-driven, TCK-verified OpenJDK distribution backed by the Eclipse Foundation. Competes with Liberica JDK as a free, standards-compliant alternative for developers; differs from BellSoft in lacking commercial enterprise support as the core offering.
• SAP (SapMachine): SAP's OpenJDK build with enterprise support for SAP customers. Directly comparable to Liberica JDK as a vendor-maintained OpenJDK distribution, though BellSoft has broader cross-industry positioning.

Broad incumbents

• Oracle (Java): The dominant incumbent in commercial Java with Oracle JDK, GraalVM, and Java SE subscriptions. BellSoft's value prop of 'Oracle JDK drop-in replacement at up to 70% lower cost' is directly positioned against Oracle's pricing and licensing.
• Red Hat (IBM): Distributor of Red Hat Build of OpenJDK and initiator of Project Hummingbird (hardened container images) — a project BellSoft's research directly influenced. Broad incumbent across enterprise Linux, middleware, and now container security.
• Amazon (Corretto): Amazon's free, multi-platform OpenJDK distribution optimized for AWS. A free hyperscaler-backed alternative that pressures paid support economics across the entire commercial JDK category, including BellSoft.
• Microsoft (Microsoft Build of OpenJDK): Microsoft's free OpenJDK distribution. Another free hyperscaler-backed alternative that competes with Liberica JDK at the free tier and pressures paid-support economics across the Java ecosystem.
• Snyk: Multi-product developer security platform including container and open-source security scanning. Adjacent competitor to BellSoft's Hardened Images in container security, though Snyk focuses on scanning/detection rather than pre-hardened base images.

Emerging players

• Chainguard: Well-capitalized startup specializing in hardened, minimal container images with near-zero CVEs. Most direct competitor to BellSoft's Hardened Images product line, with stronger venture backing and brand recognition in the container security category.

Regional players

• Alibaba (Dragonwell): Alibaba's OpenJDK distribution optimized for large-scale e-commerce and cloud workloads. Comparable to BellSoft Liberica JDK as an OpenJDK build with enterprise support, but primarily serves the Chinese market and Alibaba Cloud ecosystem.
