Open source programs
Open source programs publish their source code, and their licence lets anyone use, study, change and share them. This section gathers such programs by topic, as open alternatives to well-known commercial apps and services. Each program page shows the licence and a link to the source code repository; downloads lead to the developers' official releases, and web services open on their official sites.
