The trick to free certificates: most platforms offer the full course free and charge only if you want the "verified" upgrade. This list focuses on courses where the certificate itself is free — or the platform's name is recognizable enough that the upgrade is worth skipping.

FAQ
¿Sirven de algo los certificados de cursos online gratis?
Sí, cuando la plataforma es reconocida o las habilidades se pueden demostrar. Los nombres Google, Harvard, Microsoft y HubSpot pesan. Los proyectos y el portafolio importan más que el papel.
¿Cuál es la diferencia entre auditar y obtener el certificado?
Auditar es gratis para siempre — ves las clases y aprendes. El certificado suele exigir aprobar tareas calificadas y, en algunas plataformas, cuesta dinero salvo que consigas ayuda financiera.
¿Puedo poner cursos gratis en mi currículum?
Por supuesto. Ponlos en “Certificaciones” o “Desarrollo profesional”, con la plataforma que los emite. Un curso gratuito completado demuestra iniciativa, algo que los empleadores valoran.
