See https://github.com/cjbarber/hipchat-alternatives for more ideas.
Besides a gazillion open source wiki projects…
For a bigger far more all encompassing documentation toolchain:
Jive Disclosure: former employer (but thoroughly recommend for the right culture/environment)
Salesforce.com’s Chatter Disclosure: former employer (don’t recommend based on user experience 3+ years ago)
https://zulipchat.com is a free self-hosted alternative to hipchat.
Well that's one great list there, thanks a lot !
I'd like to share one more alternative our team created, it's a free tool called Zenkit, we'd love to have tour opinion on it:
https://zenkit.com/en/alternatives/jira-alternative/
I would suggest a Confluence alternative: https://archbee.io
Archbee is the documentation app for engineers.
Realtime knowledge base for your team, product docs for your customers.
How is Archbee different? Well, we focus on providing developer teams the best possible experience.
We are not a generic solution, meaning: you'll get a powerful realtime editor with diagramming capabilities,
Swagger, GraphQL, real code editor (Visual Studio Code embedder).

Good morning :) Thank you very much for the list - I would also suggest Kanban http ://kanbantool.com. I tent to use it every day to organize my professional life. Recommend it strongly for all the people who struggle to organize and arrange their daily duties :)
Could you also add Gitea solution?
I'lll second adding Jetbrain's Youtrack as a Jira alternative
Which of these are open source? Thanks :)
Tiagra
Ticketing? Of course you are missing Azure Boards!
As for the email from today, that Atlassian ends the support for self hosted server.. most important site right now.
But as far as I can see, no real alternative (with plugins) for Confluence.
https://backlog.com/ - a replacement of Jira + Confluence + Bitbucket.
We recently switched from Confluence to AllAnswered and really loved it. AllAnswered combines Wiki documents like Confluence and Questions & Answers similar to Stack Overflow. Great product and very easy to use. Here is their website https://www.allanswered.com
Check out Drupal Wiki as Confluence alternative. Can be self-hosted (on premise) and has almost the same structure and functionality as Confluence - even content migration from Confluence is possible see Migrate from Confluence to Drupal Wiki.
Check out Doctave if you're looking for a developer-friendly Confluence alternative that uses a docs-as-code approach. You can also use the open source documentation site generator for free. (Disclaimer: founder here)
Jira alternative (on-premises and open source) --> OpenProject (https://github.com/opf/openproject)
I would shamelessly add my project, Docmost, as an open-source alternative to Atlassian Confluence, with real-time collaboration.
Github: https://github.com/docmost/docmost
Website: https://docmost.com
https://slab.com/ is another option with emphasis on simplicity, maintaining easy to navigate organization as the team is growing, and integrating with other solutions (Github, Slack, Asana, Airtable are some examples).
