10 Open-Source Tools You Can Replace SaaS Subscriptions With

Add up the subscriptions a small team collects over a year and it's rarely small. Here are ten SaaS tools with a real open-source alternative you can self-host, all of them already in the 9pods catalog.

1. Google Drive → Nextcloud

File storage, shared docs, calendar, and video calls in one self-hosted package. Nextcloud is the closest thing to a full Google Workspace replacement that exists in open source.

2. Bitwarden Teams → Vaultwarden

A lightweight, fully compatible server implementation of the Bitwarden password manager API. Same client apps, same browser extensions, your own server.

3. Zapier → n8n

Visual workflow automation with 400+ integrations, no per-task billing, and native support for AI/LLM workflows. Covered in more depth in our n8n vs Zapier comparison.

4. Google Analytics → Plausible Analytics

A privacy-first, cookie-free analytics tool that doesn't send your visitors' data to a third party and doesn't need a cookie banner to stay compliant.

5. Notion (wiki use case) → Outline

A fast, clean team wiki and knowledge base. Not a full Notion replacement for databases and complex layouts, but excellent for documentation and internal notes.

6. Trello → Focalboard

Kanban boards and project tracking without a per-seat SaaS bill.

7. Google Photos → Immich

Automatic photo and video backup from your phone, with AI-powered search, running entirely on infrastructure you control.

8. Feedly → FreshRSS

An RSS reader that doesn't disappear if the company behind it pivots or shuts down, because there's no company behind it, it's yours.

9. Mailchimp → Listmonk

A high-performance, self-hosted newsletter and mailing list manager. No per-subscriber pricing tiers.

10. GitHub (private repos) → Gitea

A lightweight, self-hosted Git service. Full pull request workflow, issues, and CI webhooks, without a per-seat cost for private repositories.

The pattern

None of these are compromises. They're the same category of tool, sometimes the same underlying idea, run on infrastructure you control instead of someone else's. The only thing that used to make this hard was the setup and maintenance work, and that's the part 9pods exists to remove.
