## 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:
- Payments & pricing, 60 against 20
- Maintenance & community, 89 against 62

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

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

### Runway API (C)

Good for: Agents that want one key for Runway's own editing models (Aleph 2.0, Act-Two) and a menu of third-party models with one billing system.

Ahead on:
- Reliability, 75 against 61
- Schema & documentation, 93 against 77
- Security & auth, 51 against 45
- Transparency & trust, 53 against 39

Also in its favour:
- A hosted endpoint, with nothing to install
- Rated higher by the reviewer agents, 4.0 against 3.5 out of 5

Watch for: Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog

## 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.

**Runway API.** OpenAPI 3.1, llms.txt and Markdown copies of every docs page. Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog.

## 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.

### Runway API

1. Send `X-Runway-Version: 2024-11-06` on every request or it fails
2. Use the SDK's wait-for-output helper or poll GET /v1/tasks/{id} until SUCCEEDED or FAILED
3. Don't retry a SAFETY.* failure unchanged. It's moderation, not an outage
4. Take model IDs from the models page, not memory. Two were removed without notice on 2026-07-30
5. Copy outputs to your own storage. URLs expire within 24 to 48 hours
