What's the difference between "open source" and "source-available" here?

Open source means an OSI-approved license — MIT, Apache 2.0, GPL, and similar — so you can run, modify, and redistribute it freely. Source-available means the code is visible but under a license, like BSL or a custom "fair source" license, that restricts commercial use or redistribution. We label each listing with which one it actually is, since the distinction has real licensing consequences.

Is "open source" the same as "free"?

Not necessarily. The license is free to use in the sense that you can self-host at no licensing cost, but most projects here also sell a hosted or managed version, and self-hosting has its own real cost in infrastructure and maintenance time. Check each listing for what's actually free versus what's the paid tier.

How do you judge whether a project is actively maintained versus abandoned?

Recent commit activity, release cadence, and issue response time — not star count. A project with a large star count from years ago can be effectively dead, while a smaller, newer one might be actively maintained. Verify directly on the project's repository before depending on it.
