api.video vs Rendley: Hosting and Streaming Is Not Editing

There is a recurring confusion in video tooling, and it costs teams weeks. People treat "video API" as a single category, then discover halfway through a build that the API they picked does the opposite of what they needed. api.video and Rendley are a textbook example. Both are developer-first, both are "video APIs," and they solve almost entirely different problems.

api.video is infrastructure for hosting, managing, delivering, and live-streaming video. You push a file or a live feed, and it handles encoding, storage, a player, and global delivery. Rendley is an engine for editing and rendering video, assembling clips, adding captions and effects, generating AI media, and producing a finished file. One gets an existing video to viewers. The other creates the video in the first place.

This post maps both onto the video lifecycle so you can see, at a glance, which stage each one owns.

The video lifecycle, in stages

Almost every video feature can be broken into stages:

1. Create / edit — compose clips, trim, caption, brand, generate.
2. Encode / package — transcode into deliverable formats and renditions.
3. Host / store — keep the asset and its metadata.
4. Deliver / stream — serve it to viewers, VOD or live, adaptively.
5. Analyze — measure playback and engagement.

api.video is built for stages 2 through 4 (with a growing story around AI transcription and summaries that touches the edges of stage 1 and 5). Rendley is built for stage 1, with rendering that produces the file everything downstream consumes.

If you try to make api.video assemble a timeline, or make Rendley act as your live-streaming CDN, you are fighting the tool. Match the tool to the stage and both get easy.

Where api.video genuinely shines

api.video has a focused, well-executed product, and it is worth being specific about its strengths.

• Fast encoding and VOD hosting. Upload a file, get a hosted, playable video quickly, with a built-in player you can drop into a page.
• Live streaming. First-class live streaming alongside VOD, which not every video API bothers to do well.
• Wide delivery footprint. Delivery across 140+ points of presence, so playback is fast for a global audience.
• Built-in AI transcription and summaries. Transcription and summarization are available as part of the platform, handy for captions, search, and repurposing.
• Clean SDKs and pay-as-you-go pricing. Node, Python, and more, with usage-based billing that is easy to reason about.

Its pricing model reflects the focus: pay-as-you-go per minute, roughly storage at $2.85 per 1,000 minutes, delivery at $1.70 per 1,000 minutes, transcription at $0.10 per minute, plus a free sandbox (30-second cap, watermark, 24-hour auto-delete). For hosting and streaming, that is cheap and predictable.

If your job is "add video hosting and live streaming to my app," api.video is a strong, cost-effective, purpose-built choice, and Rendley does not compete with it on that job.

Where Rendley fits

Rendley is the editing and rendering layer that sits upstream of a host like api.video. It exposes that engine in three ways, which is unusual:

• In-browser SDK — @rendley/sdk, a JS/TS engine that renders client-side with WebGL and WebCodecs (FFmpeg WASM fallback). It is the actual engine behind the Rendley app, so you can embed a full editor in your product.
• REST API — api.rendley.com/v1 with an OpenAPI schema. Create projects, upload assets, call POST /export, and poll GET /jobs until it reaches a terminal state, then pull a signed URL. Long operations run as jobs; the same request returns the same edit deterministically.
• Prompt-to-video agent — /agent/sessions turns raw footage plus a brief into a finished, reviewable cut.
• Hosted MCP server — 18 tools at mcp.rendley.com so an AI client can drive the editor (paid plans only).

It also folds in 25+ AI models (video, image, voice, music, translation) and renders at up to 4K depending on plan. What it deliberately is not: a live-streaming CDN or a hosting platform. Rendley returns a finished file; it does not run your VOD library or your live infrastructure.

Side by side

The combined architecture

Here is the shape of a product that needs both, which is more common than picking one:

Rendley (edit + render)  ->  finished file (signed URL)
        |
        v
api.video (encode + host + deliver + live)  ->  viewers

Concretely: a user assembles and renders a video in your app using the Rendley SDK or the REST API. When the export job completes, your backend fetches the file from the signed URL and pushes it to api.video for hosting and delivery. For a live use case, api.video handles the stream; Rendley is not in that path at all. If you later want to edit a recorded stream, it comes back to Rendley.

The two are complementary because they never overlap on the hard part. Rendley never tries to be your streaming CDN, and api.video never tries to be your editor.

Choosing, quickly

• You need hosting, a player, live streaming, or transcription and you already have your video files → api.video, and you probably do not need an editor.
• You need to create, edit, or generate video in-app or from your backend → Rendley, then hand off to a host for delivery.
• You need users to make videos and then watch them at scale → both, in the pipeline above.

api.video is a genuinely good piece of infrastructure for the delivery half of the problem, and cheaper and more focused than trying to bolt streaming onto a general platform. Rendley's job starts one step earlier: turning raw material into the video that api.video then serves.

If the missing piece in your stack is the editing and rendering engine, you can try Rendley's editor, SDK, and API at app.rendley.com.
