imgix publishes a broad rendering API and packages managed media with delivery credits. This guide focuses on those billing mechanics. If you are actively selecting a vendor, use the sourced Keenpix vs imgix decision guide for feature fit, migration steps, and cases where imgix is the better choice.
Two different meters
imgix now sells monthly credit packages. Its published Starter package includes 100 credits, up to 50 GB of managed media, and up to 100 GB of delivery; larger packages raise both allowances. Unused credits do not roll over.
Keenpix meters optimized bytes delivered through managed cloud and does not meter the number of origin images, transformations, requests, or team members. Managed Cloudflare edge hits and application responses each count once.
| Keenpix | imgix | |
|---|---|---|
| Billing unit | Keenpix managed delivery (GB) | Credit package with media and delivery allowances |
| Transformations | Unlimited, free | Included in rendering |
| Large image catalog | No origin-image count | Managed-media allowance applies |
| Overage | One linear published rate | Plan-dependent |
| Self-host option | Yes (open source, AGPL) | No |
| Entry price | $9/mo | $25/mo for Starter (100 credits) |
Re-verified August 22, 2026 against imgix's current credit packages and costs and pricing page. Published monthly packages run from $25 Starter (100 credits) through $500 Growth Plus (3,570 credits), with $75 Basic, $150 Midrange, and $300 Growth between them. Annual packages are about 17% lower.
Free, unlimited transforms
Both products give you a powerful URL-based transformation API — resize, crop, format conversion, quality, and more. The difference is the billing consequence: with Keenpix, transformations never cost anything, so building responsive srcset sets or adding modern AVIF/WebP variants has zero pricing impact.
The self-host escape hatch
The Keenpix cloud release publishes its image engine under AGPL-3.0. You can run that version with Docker without a Keenpix license fee, while paying for and operating the infrastructure yourself. imgix is a managed platform; its service is not a self-hosted deployment path.
For teams with compliance requirements, variable budgets, or a preference for owning their stack, that optionality matters. A move can preserve the transform grammar when you control the hostname and migration path, but it still requires infrastructure and routing work.
When imgix is the better fit
imgix has years of edge-network maturity and a deep rendering feature set. If you are already invested in its API and its credit-package economics fit your media and delivery usage, there may be no reason to switch. Keenpix competes on a published managed-delivery meter, included transforms and teammates, and the self-host option — not on matching every feature of a mature incumbent on day one.

See your real number
The honest way to compare is on your own traffic. Point Keenpix at your existing origin and watch the managed-delivery meter — then decide. A migration still requires URL or hostname routing work. Or self-host with no Keenpix license fee while operating the infrastructure yourself.
