Apache Mesos

Apache Aurora is a retired Apache Mesos framework for running long-lived services and cron jobs across a shared pool of machines. It keeps jobs running by rescheduling them onto healthy machines after failures, and provides rolling updates with automatic rollback, resource quotas, multi-user deployment, and a templating-capable configuration DSL. Aurora registers services with Apache ZooKeeper for client discovery. It was distributed under the Apache License 2.0.

Chronos is a scheduling component built on Apache Mesos for running scheduled work.

Apache Maka (Incubating) is a local-first agent workspace developed under the Apache Software Foundation. It inspects projects and runs tools through a shared Runtime Host within a sandbox boundary; tools that leave the sandbox require approval. Model messages, tool calls, tool results, and how a turn ended are stored as recoverable execution facts on the user's machine, while older tool output can be omitted from later prompts without deleting the saved history. Model connections can use cloud APIs, local models, or compatible gateways, with sessions, settings, and run records kept local by default. Maka provides an Electron and React desktop application with streaming sessions, tool timelines, branching, search, recovery, artifacts, and model and sandbox settings. Its TUI/CLI supports work in a project directory and non-interactive turns, while its evaluation surface runs declarative multi-arm experiments across Maka and external subjects. Built-in tools include Read, Write, Edit, Bash, Glob, and Grep; Computer Use and catalog skills are optional. The project is under active development and Apache incubation; the README describes the macOS Apple Silicon desktop build as an early public release and notes that data formats, CLI commands, and experimental capabilities may change.

HashiCorp Nomad is a workload scheduler and orchestrator for deploying and managing containerized and non-containerized applications across on-premises environments and cloud infrastructure. It expresses workloads as jobs, schedules them onto clusters, and uses task drivers to execute different types of tasks; job specifications can include parameterized behavior, placement affinities, preemption, retries, and node rescheduling. Nomad supports integrations such as Consul for service discovery, health checking, and service mesh capabilities, and Vault for secrets. It is a competitor in the container-orchestration ecosystem, where Kubernetes ultimately prevailed. HashiCorp provides a CLI, tutorials, a sandbox, production guidance, and an Enterprise edition with features including access control, resource quotas, Sentinel integration, and encrypted cluster traffic.

Apache Kafka is an open-source distributed event-streaming platform developed by the Apache Software Foundation. It is used for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications, and can be deployed on premises, in a cluster, or through a managed service. The official repository contains Java and Scala source code, build tasks, documentation generation, and unit and integration tests.
