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
