Choose Optimizely if...

Enterprise marketing and product teams at companies where web experimentation drives material revenue and statistical rigor matters.

Avoid Optimizely if...

Engineering-led teams or startups — LaunchDarkly, Statsig, and GrowthBook are more developer-friendly and more affordable.

Choose Modal if...

Engineering teams deploying ML inference, batch ETL, or AI pipelines without wanting to manage GPU infrastructure. Developer experience is the best in the category.

Avoid Modal if...

Applications with sustained 24/7 GPU utilization — dedicated cloud GPU instances (Lambda Labs, Coreweave) are cheaper at scale.
