HelmForge vs Bitnami: A Practical Comparison

Two approaches to Helm charts

Bitnami has been the default choice for Helm charts for years. They offer hundreds of charts with consistent tooling and regular updates. So why would you consider an alternative?

The answer comes down to three things: images, licensing, and operational philosophy.

Official images vs rebuilt images

The biggest difference between HelmForge and Bitnami is what runs inside your pods.

Bitnami rebuilds every upstream image with their own base layer, entrypoint scripts, and configuration system. This means the PostgreSQL you deploy is not the official postgres image — it is bitnami/postgresql with custom scripts layered on top.

HelmForge uses the official upstream image directly. Our charts configure the application through environment variables, config maps, and init containers — without modifying the image itself.

Aspect	HelmForge	Bitnami
Base image	Official upstream	Bitnami-rebuilt
Image source	Docker Hub / upstream registry	Bitnami registry
Entrypoint	Upstream default	Custom Bitnami scripts
Update lag	Same day as upstream	Days to weeks

Licensing

HelmForge charts are MIT licensed. The chart code, templates, documentation — everything is MIT with no exceptions.

Bitnami charts are Apache 2.0 licensed, which is also permissive. However, some Bitnami images include components with different licensing terms, and the dependency on Bitnami’s image infrastructure creates a soft vendor lock-in.

Built-in backup

This is where HelmForge takes a strong stance. Every data-bearing chart includes an optional S3-compatible backup CronJob. Enable it with a few lines of YAML:

backup:
  enabled: true
  schedule: '0 3 * * *'
  s3:
    endpoint: https://minio.internal:9000
    bucket: db-backups
    existingSecret: s3-credentials

Bitnami charts do not include backup functionality. You need to build your own backup solution or use a separate tool like Velero.

When to choose each

Choose HelmForge when:

• You want official upstream images with no modifications
• You need built-in backup for databases and stateful apps
• You prefer MIT licensing with no vendor dependency
• You value security defaults (non-root, read-only FS)

Choose Bitnami when:

• You need a chart that HelmForge does not offer yet
• Your organization already standardizes on Bitnami images
• You need the broader ecosystem of 100+ charts

The bottom line

Both projects serve the Kubernetes community well. HelmForge is not trying to replace Bitnami — it is offering an alternative for teams that want official images, built-in backup, and a more opinionated approach to production readiness.
