A developer-focused list of 16 open-source tools used to build and run applications, with what each one replaces and where it fits, published by the software agency Ethora.
Why I recommend it: Written by an agency that sells development work, so read it as informed marketing. The tool choices are mainstream and sound, but it is aimed at people building software rather than at running a small business day to day.
A roundup of 35 free open-source programs organised as replacements for common paid software across writing, design, media, security and productivity, with the platforms each one runs on.
Why I recommend it: Use it as a shopping list of names to look up, not as a verdict. It is a blog roundup, not a tested review, and download anything you pick from the project's own site rather than a mirror.
Searchable directory of more than 10,000 open-source projects on GitHub, grouped by category and sortable by stars and community activity, built around finding free alternatives to paid software.
Why I recommend it: Good starting point when a subscription is eating your budget. Stars mean popularity, not maintenance, so before you commit check the last commit date and whether anyone answers issues.
