Cascade

Self-hosted visual AI workflow editor built on TierFall. Tier routing is on the canvas, not in a settings panel.

Why

n8n alternatives are everywhere. Cascade is the one that:

• Self-hosts by default. One docker compose up brings up the full stack.
• Compiles workflows to TypeScript. The editor is scaffolding; the artifact you own is a .ts file that imports @tierfall/core and runs without Cascade.
• Routes locally first, falls to cloud only when needed. TierFall's fall, never climb policy makes vendor neutrality concrete.

Quick start

git clone https://github.com/tierfall/cascade.git
cd cascade
cp .env.example .env
docker compose up -d

Open http://localhost:3001 → hit /setup → finish the wizard.

To run the bundled demo (local Ollama + cloud fallback via TierFall):

docker compose --profile demo up -d
