There’s no single best video hosting API — the right one depends on how you want to be billed (per gigabyte vs per minute vs per plan), whether you need live streaming, and whether an AI agent has to operate it. Bunny and rehelios are the per-GB options, Mux and Cloudflare Stream bill per minute, Cloudinary pools everything into credits, and Vimeo and Wistia are products around video rather than raw infrastructure. Here’s how to pick.
Every “top video APIs” list ranks the same names in a different order and calls it a verdict. That’s not useful, because the deciding factor usually isn’t which API is “best” in the abstract — it’s which billing model matches your catalog, and which capabilities you actually need. So this is organized by that instead.
Start with the billing model
This is the choice that moves your bill the most.
| API | Billing model | Genuinely good at |
|---|---|---|
| rehelios | Per GB stored + delivered, free encoding | Per-GB cost, agent-native (CLI + MCP), long-tail catalogs |
| Bunny Stream | Per GB, very low rates | Cheapest raw per-GB delivery, broad CDN ecosystem |
| Mux | Per minute encoded/stored/delivered | Deep data/QoE analytics, live, enterprise support |
| Cloudflare Stream | Per minute stored + delivered | All-in on Cloudflare, one invoice, simple setup |
| api.video | Per minute, free encoding | Simple metered pricing, live + VOD, real self-serve |
| Cloudinary | Unified credits pool | Heavy on-the-fly media transforms + image/video DAM |
| Vimeo | Plans / OTT | Turnkey monetization + native TV apps (OTT) |
| Wistia | Seats / plans | Video-as-marketing: engagement analytics, CTAs, lead capture |
Billing models as published by each provider, mid-2026. Rates change — verify on each provider’s site.
The split that matters: per-minute pricing charges the same for a video whether one person watches it or a thousand, and usually meters encoding too, so a long, rarely-watched library gets expensive. Per-GB pricing tracks the bytes you actually store and deliver. Per-plan products (Vimeo, Wistia) cap usage and bundle a lot of product around the video. For a detailed breakdown of why the model matters more than the cents, see video hosting pricing compared by model.
Then narrow by what you actually need
- You want the lowest predictable cost on a large VOD catalog. Per-GB, so Bunny or rehelios. rehelios adds free encoding and an agent-native surface; Bunny is the bare-metal-cheap option inside a broader CDN.
- You need deep playback analytics or live at scale. Mux is the mature choice, at a per-minute, enterprise-shaped price.
- You’re already on Cloudflare. Cloudflare Stream keeps video on the same invoice and platform.
- You need heavy in-flight media manipulation. Cloudinary, if you’re already using it for images and want video in the same credits pool.
- You want turnkey monetization or TV apps. Vimeo OTT — a different product from raw infrastructure.
- Video is a marketing channel. Wistia, for the funnel tooling around it.
- An AI agent has to put video live on its own. This is the newest axis, and it’s where the field is thin.
The axis most lists miss: can an agent drive it?
In 2026 the question isn’t only “which API,” it’s “can my automation or AI agent operate it without a human in a dashboard.” Mux, Bunny, and Cloudflare have all shipped MCP servers as add-ons to existing platforms; rehelios and VideoDB are built agent-first. If an agent generating or importing video needs to host and deliver it end to end, that changes the shortlist — we mapped it in MCP video servers, compared.
How to pick, in one pass
- Match the billing model to your catalog. Long-tail or mixed-length VOD → per-GB. Short, heavily-watched clips → per-minute can be fine.
- Check the hard requirements. Live streaming, DRM, or native TV apps rule some options in or out fast.
- Decide who operates it. A human in a console, your backend via REST, or an AI agent via MCP — the last one narrows the field.
- Verify current pricing. Every provider gates its top tier behind sales; confirm the numbers before you commit.
rehelios sits in one clear spot on this map: per-GB storage and delivery with free encoding, signed playback, and a CLI + MCP server an agent can drive itself. If that’s the corner you’re in, compare it directly or start free. If you need live, DRM, or turnkey monetization, one of the others above is the honest answer.
If you’re picking for a specific situation
This post maps the whole category. These go deeper on one context each, with the arithmetic worked out rather than left abstract:
- Best video hosting for online courses — one 500 GB library priced on every billing model.
- Best video hosting for developers — API surface, webhooks, resumable uploads and automation.
- Best video hosting for your website — sorted by why you’re leaving YouTube.
- Best video hosting for Webflow and Framer — embedding without giving back the page speed.
- The cheapest video hosting, calculated — three catalog sizes, and the two points where per-minute billing wins.
