What is the difference between Mux, Cloudflare Stream, and api.video?

All three turn a raw video upload into an adaptive stream you can play anywhere, but they differ in scope and pricing. Mux is a full video platform: you get adaptive-bitrate HLS encoding, a polished open-source player, auto-generated captions, per-title and 4K encoding, DRM, and detailed playback and engagement analytics, billed per minute separately for encoding, storage and delivery, with a free tier of 100,000 delivery minutes a month. Cloudflare Stream is a deliberately simple streaming product built on Cloudflare's own global network: encoding is free, and you pay only for minutes stored and minutes delivered, with no separate per-gigabyte bandwidth charge, which makes the bill very predictable. api.video is focused on upload and encoding: it offers free unlimited encoding and low per-minute storage rates, which is attractive for large catalogues, but its delivery price per minute is higher than Mux's and its free sandbox caps clips at 30 seconds with a watermark. The quick rule: Mux is the feature-and-analytics leader, Cloudflare Stream is the simplicity-and-cost leader, and api.video is the encoding-cost leader.

Which video API is cheapest?

It depends almost entirely on your mix of storage, encoding and delivery, so model your own numbers before committing. Cloudflare Stream is the easiest to reason about because it meters only two things — roughly $5 per 1,000 minutes stored and $1 per 1,000 minutes delivered — with free encoding and no separate bandwidth bill, which usually makes it the cheapest and most predictable for delivery-heavy consumer apps. Mux bills encoding, storage and delivery separately (storage around $0.0024 per minute per month and delivery around $0.0008 per minute, with the first 100,000 delivery minutes free each month), so it can be very competitive at low-to-medium scale thanks to that free tier and lower delivery rate. api.video's free unlimited encoding helps upload-heavy catalogues, but its per-minute delivery rate is more than double Mux's in published comparisons, so it tends to lose on delivery-dominated workloads. Vendor cost estimates disagree depending on the scenario, so run your expected monthly minutes through each provider's current pricing page rather than trusting a single benchmark.

Does Cloudflare Stream charge for bandwidth or egress?

No — and that is one of its biggest advantages. Cloudflare Stream does not bill per gigabyte of bandwidth or charge egress fees the way raw object storage plus a CDN would. Instead it meters video by the minute: minutes of video stored and minutes of video delivered, with encoding included for free. Because delivery is priced in minutes watched rather than gigabytes transferred, your bill does not spike when a video is high-bitrate or when traffic surges, and there is no surprise egress line item. This is a meaningful difference from a do-it-yourself setup on S3 plus CloudFront, where bandwidth and egress can dominate the cost and are hard to predict. If cost predictability matters more than having the deepest analytics or DRM feature set, Stream's minutes-only model is the main reason teams choose it.

Which video API is best for an LMS or course platform?

For a learning platform or course product, the deciding factors are usually playback analytics, captions, and sometimes DRM to protect paid content — and that profile favours Mux. Mux gives you engagement analytics (how far learners watch, where they drop off), auto-generated captions for accessibility and compliance, per-title encoding for quality, and DRM options for protecting premium courses, all through one API and a ready-made player. Cloudflare Stream is an excellent choice too if your priority is simple, low, predictable costs and you do not need deep per-viewer analytics or advanced DRM — its signed URLs and tokenised playback still let you gate content behind a login. api.video can work for large course catalogues where encoding volume is high, given its free encoding. A common pattern for course-selling platforms is Mux when analytics and content protection justify the per-minute cost, and Cloudflare Stream when keeping the margin on each course high is the priority.

Do I need a video API at all, or can I just use S3 or YouTube?

You can host video yourself or embed YouTube, but both have real drawbacks that video APIs exist to solve. Storing an MP4 in S3 and serving it through a CDN means no adaptive bitrate (viewers on slow connections buffer instead of dropping to a lower quality), no automatic transcoding to multiple renditions, no HLS/DASH packaging, no built-in player analytics, and bandwidth-and-egress bills that can balloon unpredictably. Embedding YouTube is free but puts your content on someone else's platform with their branding, recommendations, ads and the risk of takedowns, which is unacceptable for paid or private content. A video API like Mux, Cloudflare Stream or api.video handles transcoding, adaptive-bitrate packaging, global delivery and a player for you, and lets you keep the content private and on your own domain. If your app shows more than a handful of static clips — especially user-generated uploads or paid content — a dedicated video API is almost always worth it over rolling your own.

Mux vs Cloudflare Stream vs api.video 2026: Choosing a Video API

The Decision Every App With Video Eventually Faces

Adding video to a product looks simple until you try to do it properly. You upload an MP4, serve it from storage, and it works on your laptop — then a user on a train watches it buffer to a halt, a 4K phone recording costs you a fortune in bandwidth, captions are missing, and you have no idea how far anyone actually watched. Real video means adaptive-bitrate streaming (HLS or DASH), transcoding every upload into multiple renditions, global delivery, a player that handles all of it, and ideally analytics and content protection. Building that yourself on top of S3 and a CDN is a project in its own right.

That is what a video API is for. In 2026 three of them dominate the developer choice — and they are not interchangeable. Mux is the feature-rich platform: adaptive encoding, a polished player, deep analytics, 4K, DRM and auto-captions. Cloudflare Stream is the simple, low-cost option built on Cloudflare's global network, metered only by the minute with free encoding and no egress bill. api.video leans on free unlimited encoding and low storage rates, aimed at upload-heavy catalogues. Pick the wrong one and you either overpay for features you will never use or hit a wall where the cheap option cannot do what your product needs. This guide maps each to the situation it was built for.

Mux — The Feature-Rich Video Platform

Mux is the most complete of the three and the one most teams reach for when video is core to the product. You POST a source file or a URL, and Mux handles adaptive-bitrate encoding into an HLS stream, stores it, and delivers it globally. Around that it stacks the things a serious video product needs: a polished open-source player (Mux Player), auto-generated captions, per-title and 4K encoding, DRM for protecting paid content, live streaming, and — its signature feature — deep playback and engagement analytics that tell you not just how many views but where viewers drop off, rebuffer, or fail to start.

Mux prices by the minute, and it bills encoding, storage and delivery separately. That sounds complex, but it is transparent: you pay for minutes encoded once, minutes stored per month, and minutes delivered. In mid-2025 Mux cut prices across the board — encoding, storage and delivery all dropped by roughly 17–23% — and it now offers a genuine free tier: upload and store up to 10 assets and deliver 100,000 minutes free every month, including the player, captions and analytics. For an early-stage product that free allowance covers a surprising amount of real traffic.

Where Mux shines:

Products where playback analytics drive decisions — courses, media sites, creator platforms

Apps that need captions, 4K, per-title encoding or DRM out of the box

Teams that want one polished API and player rather than assembling pieces

Early-stage apps that benefit from the 100,000-minute free tier

The trade-off: Mux's separate per-minute metering for encoding, storage and delivery means your bill has more moving parts than Cloudflare Stream's, and at very high delivery volumes a simpler minutes-only competitor can undercut it. You are paying for the richest feature set in the category — which is exactly right when you use those features and overkill when you do not.

Cloudflare Stream — Simple, Predictable, and Cheap

Cloudflare Stream takes the opposite philosophy: do less, price it simply, and make the bill predictable. Encoding to adaptive bitrate is included for free. You then pay for just two things — minutes of video stored (about $5 per 1,000 minutes) and minutes of video delivered (about $1 per 1,000 minutes) — with no separate per-gigabyte bandwidth charge and no egress fees. Because delivery is metered in minutes watched rather than gigabytes transferred, a high-bitrate 4K video does not cost more to deliver than a low-bitrate one, and a traffic spike does not produce a surprise bandwidth invoice.

It runs on Cloudflare's own global network, so delivery is fast worldwide without you configuring a CDN, and it integrates cleanly with the rest of the Cloudflare stack — Workers, R2, Pages and Access. It supports live streaming (including low-latency and WebRTC-based input), signed/tokenised URLs for gating private or paid content, and a built-in player and simple embed. A small bundle option exists for getting started cheaply.

Where Cloudflare Stream shines:

Teams that want the simplest, most predictable bill in the category

Apps already on Cloudflare (Workers, R2, Pages, Access)

Delivery-heavy consumer apps where minutes-only pricing beats per-GB models

Projects that value no egress surprises over deep analytics or advanced DRM

The trade-off: Stream's analytics and content-protection features are deliberately lighter than Mux's. You get solid playback and basic analytics and signed URLs, but not Mux's granular per-viewer engagement data or its full DRM toolkit. If your product's value depends on understanding exactly how people watch, or on studio-grade content protection, that gap matters; if it does not, Stream's simplicity and cost are hard to beat.

api.video — Encoding-First for Upload-Heavy Catalogues

api.video is built around one strong claim: encoding is free and unlimited. For workloads that ingest and transcode enormous volumes of video — large user-generated catalogues, archives, or platforms that re-encode constantly — not paying per minute to encode is a real structural advantage. It pairs that with low per-minute storage (as low as roughly $0.00285 per minute stored) and a full API covering upload, adaptive-bitrate delivery, a player, live streaming, and features like thumbnails and basic analytics.

Where api.video is less competitive is delivery. Its delivery rate (around $0.0017 per minute delivered in published pricing) is more than double Mux's typical delivery rate, so for apps whose cost is dominated by *watching* rather than *uploading*, the free encoding does not offset the higher delivery bill. Its free sandbox is also not a true free tier: clips are capped at 30 seconds, watermarked, and auto-deleted after 24 hours, so it is for evaluation, not production.

Where api.video shines:

Upload- and encoding-heavy products where transcoding volume is the main cost

Large catalogues or archives with lots of stored video relative to views

Teams that specifically want to remove encoding from the cost equation

The trade-off: the higher delivery rate means api.video can end up the most expensive of the three for delivery-dominated apps, and the sandbox limits make it harder to trial realistically. Model your storage-to-delivery ratio honestly before choosing it.

Pricing Models Side by Side

The three price the same underlying work — encode, store, deliver — in three different shapes, and that shape is what determines who wins at your volume:

Mux — meters encoding, storage and delivery separately, all per minute. Storage around $0.0024/min/month, delivery around $0.0008/min, first 100,000 delivery minutes free monthly. Richest features; most line items. Prices dropped ~17–23% in 2025.

Cloudflare Stream — free encoding, then ~$5 per 1,000 minutes stored and ~$1 per 1,000 minutes delivered, no per-GB bandwidth, no egress. Simplest and most predictable bill.

api.video — free unlimited encoding, low storage (~$0.00285/min), but higher delivery (~$0.0017/min). Best when encoding volume dominates and delivery is modest.

A critical caveat: published head-to-head cost estimates disagree, because the answer flips depending on your storage-to-delivery ratio and bitrate — and several of the loudest comparisons are vendor-authored. Treat any single "X is cheapest" claim with suspicion and run your own expected monthly minutes through each provider's current pricing page. All three change prices; the numbers above are directional, not a quote.

Developer Experience and Integration

All three are genuinely developer-first: REST APIs, webhooks for asset and encoding events, SDKs in the major languages, and ready-made players you can drop into a web or mobile app. Practical differences:

Mux has the most mature ecosystem — official React, Next.js and framework components, a well-documented player, signed playback tokens, and (new in late 2025) an open-source @mux/ai toolkit for summaries, chapters, moderation and caption translation. It is the smoothest if you want video *and* video intelligence.

Cloudflare Stream is simplest to wire up if you are already in the Cloudflare ecosystem: it sits next to Workers, R2 and Access, and tokenised URLs make private/paid gating straightforward. The embed and player are intentionally minimal.

api.video offers clean SDKs and an upload-focused API with delegated (client-side) uploads that are handy for user-generated content, so browsers upload straight to api.video without proxying through your server.

For a Next.js or React app specifically, Mux's first-party components make it the least-friction integration, with Cloudflare Stream close behind if you are already on Cloudflare.

How to Choose

Work through these in order:

Is video core to your product, and do you need analytics, captions, 4K or DRM? If yes, use Mux — it is the only one of the three with the full feature set, and the 100,000-minute free tier makes starting cheap.

Do you want the simplest, most predictable bill — and are you already on Cloudflare (or want no egress surprises)? If yes, use Cloudflare Stream — free encoding and minutes-only pricing with no per-GB bandwidth is the cost-predictability winner.

Is your workload upload- and encoding-heavy, with lots of stored video relative to views? If yes, evaluate api.video — free unlimited encoding is a structural saving, but model your delivery minutes first because its delivery rate is the highest of the three.

Are you showing only a handful of static clips? Then you may not need any of them — but the moment you add user uploads, adaptive streaming, private/paid content or real traffic, a video API pays for itself over a do-it-yourself S3-plus-CDN build.

Most teams building a serious video product — a course platform, a creator or social app, a media site — land on Mux for its analytics and features, or Cloudflare Stream when margin per view and cost predictability matter most. api.video is the specialist pick for encoding-dominated catalogues.

The Bottom Line

Three video APIs, three different bets about where the hard part of video is:

Mux — the feature-rich platform: adaptive encoding, a polished player, deep playback and engagement analytics, captions, 4K and DRM, plus a real 100,000-minute free tier. Per-minute billing across encoding, storage and delivery; the richest set of capabilities and the right default when video is central to your product.

Cloudflare Stream — the simple, cheap, predictable option: free encoding, minutes-only pricing (~$5/1,000 stored, ~$1/1,000 delivered), no per-GB bandwidth and no egress, served on Cloudflare's global network. Lighter analytics and DRM, but the easiest bill to forecast and often the lowest for delivery-heavy apps.

api.video — the encoding-first specialist: free unlimited encoding and low storage, ideal for upload-heavy catalogues, with a higher delivery rate that makes it best when storage, not watching, drives your cost.

There is no universal winner — there is the model that matches your storage-to-delivery ratio, your need for analytics and protection, and the stack you already run on. Decide those first and the choice becomes obvious.
