WayCast
Turn any company's URL into a polished vertical brand‑film — script, voiceover, city backgrounds, final MP4 — without opening an editor.
Open‑source · self‑hosted · local‑first. No avatars, no stock‑footage clichés — clean institutional motion‑graphics. The AI agent driving it is the writer, so it runs with zero cloud keys if you want.

60‑second try
npx waycastai doctor # what your machine can do
npx waycastai make https://stripe.com --reuse-bg wjdigital # URL → brand package in ./brands/
npx waycastai render <slug> --quality standard # → ./output/*.mp4
Everything lands in your folder. Prefer a UI? npx waycastai console → http://127.0.0.1:4178.
What it makes
A 1080×1920, 8‑shot institutional brand film — cover → who‑we‑are → what‑we‑do → why → how → who‑it‑powers → beliefs → CTA — data‑driven from a reusable block library, EN + ZH, real‑voice narration, per‑shot city backgrounds.

Why WayCast is different
Most "URL → video" tools are paid SaaS, or wrap a cloud API behind talking‑head avatars. WayCast is the opposite end:
| WayCast | |
|---|---|
| Agent‑native | Driven by Claude Code / any agent via MCP — the agent writes the storyboard itself, so good copy needs no LLM key |
| Local‑first | Renders locally; bundled local TTS (Kokoro EN / CosyVoice ZH same‑voice clone, Apache‑2.0) — or BYO cloud key |
| Zero‑dependency | Pure Node + ffmpeg. No framework lock‑in |
| Style | Clean text‑motion brand films — no avatars, no random stock B‑roll |
| Bilingual | English + 简体中文 first‑class (most OSS video tools are EN‑only) |
| Yours | Self‑hosted, dual‑licensed, keys stay in your .env |
Three ways to drive it
- CLI / npx —
npx waycastai make <url>→render. - Any coding agent — clone, point Claude Code at it; it reads
CLAUDE.mdand authors + renders the film itself. Seedocs/agent-usage.md. - MCP —
claude mcp add waycast -- npx waycastai mcp→ 7 tools (waycast_scrape / write_brand / render / …). Seedocs/mcp.md.
How it works
URL ─▶ scrape ─▶ brief (+brand color) ─▶ script (EN/ZH copy) ─▶ pick city images
▼
brand package (brand.json + storyboard.json + vo.json + bg)
▼
local TTS ─▶ retime to narration ─▶ render (hyperframes) ─▶ MP4
Every stage has a keyless local/deterministic fallback and an optional BYO‑key upgrade. Anti‑fabrication is enforced — the copy only uses facts from the site.
Backends (all optional)
| Capability | Local (offline) | Cloud (BYO‑key) |
|---|---|---|
| Voiceover (required, pick one) | Kokoro (EN) / CosyVoice (ZH) | OpenAI / ElevenLabs / Azure |
| Copywriting | deterministic draft or the driving agent | Anthropic / OpenAI |
| City images | --reuse-bg / drop your own |

Keys go in .env (.env.example). npx waycastai doctor shows what's ready. Full setup: docs/install.md.
Status — pre‑alpha (honest)
Core pipeline (URL → standard MP4) is verified end‑to‑end via the local path. Cloud LLM/TTS/image adapters are implemented but not yet live‑tested; a one‑click Docker image for the local models is WIP; Windows is untested (use WSL). It's a self‑hosted dev tool, not a turnkey consumer app. Changelog: CHANGELOG.md.

Dual‑licensed MIT OR Apache‑2.0 — your choice. Third‑party components (local TTS models, fonts, CC‑BY sample images, GSAP via CDN) in NOTICE.
