The right choice depends on your needs
Thumbor and Transloadit were built to solve real production problems. Both are used in serious systems, and both have strengths.
Choose based on your workload: file types, delivery targets, and how much control you need over upload and processing. If you need broad file processing with a self-hostable upload stack and an API that has been stable for 17 years, Transloadit is worth a trial. If your needs are narrower, Thumbor may be the better fit.
Best for
- ✓Teams needing a free, self-hosted image transformation service with smart cropping
- ✓Projects requiring on-the-fly URL-based image resizing and optimization
Not ideal for
- •Teams needing video, audio, or document processing
- •Projects requiring managed cloud hosting or SLA-backed uptime
