Fork yeah: We’re adding ten new open source projects to EmeritOSS

Last month, we announced Chainguard EmeritOSS, a new program we developed to support mature open source projects and promote long-term stability in the open source community. When a project no longer requires continuous upkeep or the maintainers need to step away, Chainguard EmeritOSS will step in.

Without a structured transition model, organizations that depend on these mature projects are left vulnerable. EmeritOSS helps fill this gap by updating dependencies, building from source, and cutting releases. We began with three early inductees: Kaniko, Kubeapps, and ingress-nginx.

Today, we’re excited to announce that another ten powerful open source projects are now joining the EmeritOSS family. These tools encompass object storage, monitoring, data processing, backup integrations, and observability, each bringing unique capabilities. Let’s get into it.

Object storage

MinIO

MinIO is a high-performance, open source object storage system that is fully compatible with the Amazon S3 API. Designed for cloud-native and Kubernetes environments, MinIO provides scalable, durable storage for data lakes, backups, artifact storage, and machine learning workloads. Its lightweight architecture and strong consistency model make it a popular choice for organizations that need reliable object storage they can run anywhere, from on-premises infrastructure to public cloud environments.

We began providing a free MinIO container image in October 2025, and we are excited to continue supporting the project.

Monitoring and exporters

Prometheus PushProx

Prometheus PushProx is a clever proxy and client solution that lets Prometheus scrape targets even behind NATs or firewalls, all while retaining the familiar pull-based model. This makes it much easier to monitor environments where direct scraping isn’t possible.

Cassandra Exporter

Cassandra Exporter is a standalone metrics exporter for Apache Cassandra® that exposes rich performance and usage metrics from Cassandra in a Prometheus-friendly format. It’s ideal for observing and managing your Cassandra deployments using dashboards and alerts.

Prometheus JSON Exporter

This is a flexible Prometheus exporter that scrapes arbitrary JSON APIs and turns them into metrics using JSONPath configuration. This exporter is highly configurable and great for integrating non-standard sources into your observability stack.

Prometheus Exporter for RabbitMQ

Prometheus exporter for RabbitMQ exposes broker, queue, connection, and exchange stats via the Management API. This exporter works with legacy RabbitMQ 3.x versions and provides extensive filtering and configuration capabilities for monitoring RabbitMQ infrastructure. It’s especially useful for message-queue monitoring and alerting.

Prometheus Exporter for Python Redis Queue 

This is a Prometheus exporter for Python RQ (Redis Queue) workers, exposing job queue metrics such as processing time and counts, allowing you to monitor background workloads more effectively. It exposes an HTTP endpoint, typically /metrics, that Prometheus can scrape for data.

Data collection and processing

logstash-filter-range

This Logstash filter range plugin allows you to define numeric or string ranges and check whether a given field’s value falls within them, making it easy to tag events, drop unwanted data, or apply conditional processing based on range-based criteria.

Database and backup tools

PgCat

PgCat is a PostgreSQL connection pooler and proxy that supports sharding, load balancing, failover, and mirroring. It’s a robust alternative to the classic PgBouncer.

Velero plugin for OpenStack

The Velero plugin adds support for backup/restore operations to Velero for OpenStack resources, including Cinder volumes, Swift containers, and Manila shares. It provides volume snapshotting and object storage capabilities for OpenStack environments.

Node and system insights

k8s-node-collector

The k8s-node-collector project provides a Kubernetes node information collector to gather file system, process, and system data. It produces structured JSON output that is useful for auditing, compliance checks, or custom integrations.

EmeritOSS continues to grow

EmeritOSS exists for the projects that have earned their stripes. They’ve shipped, scaled, and supported real systems, and while their maintainers may be ready to step back, the software itself still has plenty of life left.

EmeritOSS provides continuity-focused stewardship for mature projects by maintaining public, non-competitive forks, addressing security issues through dependency updates and releases, and clearly documenting support boundaries. We focus on keeping proven software safe and accessible, not on adding new features.

Our forked, stability-focused versions will remain freely available on GitHub in source form only. Organizations that prefer a secure, continuously maintained container image or APK can opt for our commercial distribution.

Stay tuned for more integrations, container images, and community stories as these projects evolve. If you have another project that you would like us to consider for support through the EmeritOSS program, please submit it for consideration.
