Recommended software

»If you could recommend one, and only one software for this job, what would it be?«

These are our answers to that question. Our goal was to recommend software packages that, given all pros and cons, look like good default solutions to give a try. Without any doubt, there are worthy alternatives, and we mention a few of them, too. Where we couldn’t find a suitable software yet that both satisfies the requirements and complies with our principles, we’ve added a Wanted: item

Some sections list advanced items that produce great results, if you’re willing to put in some serious learning effort. Also, niche items that we have found useful for solving fringe problems.

Finally, some sections mention standards that your chosen solution should support, if interoperability, independence, and long-term strategic considerations matter to you.

Our Principles for Picks

We take these as our guidelines. Consider them a profile of our audience that we keep in mind.

  • Standards over lock-in. We prefer solid support of standards over proprietary concepts and implementations.
  • Frameworks over standalone. Wherever possible we prefer add-ons, managed within a proven framework that reliably handles non-functional requirements like user management, security and privacy.
  • Credibility and privacy over broken trust. We prefer open source software maintained by people with an untainted track record.
  • Functionality over beauty. We rather work with an ugly software setup that does the job, than mitigate functional deficiencies of a good-looking one, by workarounds.
  • Resistance over assimilation We prefer to keep software out of our workspaces that is not open source, over looking for integration workarounds. It isn’t futile.

Our current software watch list

We’re monitoring a few projects that are close to being included in our recommendations

There are various reasons we can’t recommend them yet (e.g., no official releases yet; parts not being open-sourced yet; commonly expected features missing; you get the picture).

Waiting for…

  • Audio editing: Tenacity (fork of Audacity) – Waiting for first production release (they have a beta release now).
  • Workgroup conversations: Element – Waiting for threaded conversations feature in phone & desktop clients
