Awesome Open-Source Alternatives to SaaS - GitHub list of open-source alternatives to well-known SaaS | Product Hunt

Awesome list of open-source startup alternatives to established SaaS products. Maintained by folks at Runa Capital.

Also checkout our ROSS index: fastest-growing open-source startups, every quarter.

Criteria

Open-source company is added to the list if:

  1. Its product is strongly based on an open-source repo
  2. It has a well-known closed-sourced competitor, solving a similar business problem
  3. It is a private for-profit company, founded in the last 10 years
  4. Its repo has 100+ stars on GitHub

Things change really fast in the startup world, so this list can neither be fully complete, nor 100% up to date.

Don't hesitate to contribute and add new startups. Let's build the most comprehensive list together.


Startup List

All startups in the list are sorted by categories and names in an alphabetical order. If you click on the stars badge, you will get to a product's repo. Have a good search!

  • Add Vikunja

    Add Vikunja

    Hi, founder of Vikunja here.

    Vikunja is a project management / to-do list application, replacing tools like trello, todoist, asana, etc. We have a for-profit SaaS version available called Vikunja Cloud.

    I would love to add the project to the list, however, it does not have 100+ stars on a single repo. Main reason is probably we don't primarily use github for code, we're only mirroring the code here. If you squint a bit, you could count the stars of the frontend and api repos as one, which would push it over the 100 stars requirement.

    Just putting this up for discussion, any way to add Vikunja to the list? Or should I rather wait until we hit the 100+ stars for a single repo here on github?

  • Unfortunately, Modulz repo is not a tool but

    Unfortunately, Modulz repo is not a tool but "An open-source UI component library" and it was acquired recently

    Hi! I love what you guys are doing at RunaCapital, it helps drive awareness towards great OSS tools. I'm in the design space so I'm curious about anything relevant on that field (other than Penpot, of course). Modulz is listed as an alternative to Figma but the repo you link is about open UI components, sort of a designers toolkit, but not a tool. Their tool would be this one https://www.modulz.app/ but it has never released any alpha or beta and very recently they announced they had been acquired by WorkOS https://www.modulz.app/blog/modulz-acquired-by-workos. It doesn't look very good for the future of that tool. I would suggest you change the description for Modulz. Do you need a specific pull-request or will you do it yourselves?

    Recommendation for addition: Concrete CMS (Formerly Concrete5)

    Yeah not sure why this isn't in the list, as it's really awesome : https://www.concretecms.com

    Formerly Concrete5, now called Concrete CMS (due to versioning stuff). I've been using it for many years to build websites and the devs are totally awesome! IMO worth adding, and they're super invested in it being FOSS too.

  • Many of the listed projects/start-up are not Open Source

    Many of the listed projects/start-up are not Open Source

    Hi! Just had a scan through the project list and noticed many of these are generally not considered to be "Open Source" as per the common definition.

    • FusionAuth - Can't find any significant open source offering.
    • Tracardi - Applies commons clause.
    • Chaskiq - Applies commons clause.
    • Gravitl (netmaker) - SSPL License.
    • Lunatrace - Very mixed, Large portions BSL (Including lunatrace portion)
    • Airbyte - Defaults to Elastic License 2.
    • Memgraph - Mixed BSL and custom enterprise.
    • Graylog - SSPL.
    • Outline - BSL.
    • Sentry - BSL.
    • Uptrace - BSL.
    • Castled - Can't find any significant open source offering.
    • OpenReplay - Elastic License 2.
    • N8N - Sustainable Use License.

    I think all the BSL licenses were backed by Open Source licenses, making them a bit of a grey area, but in many cases, applying your 10-year start-up window, it does mean that the source be be non-Open-Source for half that 10 year time, then somewhat outdated for the remainder.
