https://www.gumlet.com is one of the service which takes all of this into account and makes all essential image optimisations available via nice and tidy API.
Why should I pick Gumlet over alternatives? There are a lot of competitors such as kraken.io
- cheaper pricing and no minimum monthly payments
- global image processing locations - ensures lowest latency regardless of location of your users
- no lock-in and wide variety of cloud storage support including DigitalOcean Spaces
- prompt support - less than 8 hour response time for all users
- GIF support
- especially compared to kraken, we charge only $0.1 per GB compared to their lowest pricing of $1 per GB
- strong enterprise focus - lot of features planned for enterprise support.
Are there plans for a self-hosted option? Some business might be scared of being so dependent on Gumlet's uptime for their mission critical image processing.
Gumlet seems to cater towards processing images on the fly, which is what a lot of your competitors also do. It might be interested to also cater towards using Gumlet as a service to pre-process images as part of a pipeline.
I am just thinking aloud, I have no real basis for these ideas at the moment. Just my two cents.
I wish you the best of luck and I'll keep Gumlet in mind, the homepage looks very sleek.
