## Which one, for what

### framefields (C)

Good for: Coding agents that write motion graphics, data stories, title cards and 3D product shots as code and render them locally or on their own GPU.

Ahead on:
- Reliability, 61 against 15
- Schema & documentation, 77 against 15
- Agent ergonomics, 74 against 27
- Security & auth, 45 against 20
- Payments & pricing, 60 against 20

Watch for: First published on 5 October 2026 and declared beta

### Kling AI API (F)

Good for: Buyers who want Kling's quality and price and are willing to sign JWTs and read the docs in a browser.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: Developer docs, API terms and package sizes render only with JavaScript

## Verdicts

**framefields.** A free Apache-2.0 library that renders video from TypeScript on the GPU, with lint and QA codes an agent can act on. It is fifteen days old, called beta, and its Claude Code install command names a plugin directory entry that was not found on 20 October 2026.

**Kling AI API.** Kling 3.0 from $0.084 a second, with audio from $0.126, and failed generations deduct no units. Developer docs and API terms render only with JavaScript, and Kling 4.0 isn't on the API as of 17 October 2026.

## Before you call either

### framefields

1. Add the plugin with `/plugin marketplace add gatewai-dev/framefields` first; the official-directory install was not found on 20 October 2026.
2. Approve only the skia-canvas install script, as the getting-started page shows, or imports fail with a missing `skia.node`.
3. Check with `comp.lint()` and `renderFrameGrid` before a full `renderVideo` encode.
4. Call `process.exit()` after rendering; native GPU threads keep the script alive.
5. Preload vision models into `FRAMEFIELDS_MODELS_DIR` for offline or CI renders.

### Kling AI API

1. Sign a JWT (HS256) with `iss` set to your AccessKey and a 30 minute `exp`, then send it as a bearer token
2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it
3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds
4. Don't plan on Kling 4.0 or clips over 10 seconds through this API yet. Kling 4.0 isn't on the developer platform as of 17 October 2026
5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls
