Developer Experience

FAL.AI

import { fal } from "@fal-ai/client";

fal.config({ credentials: process.env.FAL_KEY });

const result = await fal.subscribe("fal-ai/flux-pro", {
  input: {
    prompt: "A serene mountain landscape at sunset",
    image_size: "landscape_16_9"
  }
});

console.log(result.data.images[0].url);

Pros:

• TypeScript SDK with good types
• Webhook support for long-running jobs
• Real-time status updates via subscribe

Cons:

• Documentation could be more detailed
• Smaller community

Replicate

import Replicate from "replicate";

const replicate = new Replicate();

const output = await replicate.run(
  "black-forest-labs/flux-pro",
  {
    input: {
      prompt: "A serene mountain landscape at sunset",
      aspect_ratio: "16:9"
    }
  }
);

console.log(output);

Pros:

• Excellent documentation
• Large community with examples
• Simple, intuitive API

Cons:

• Slightly higher prices

When to Use Each

Choose FAL.AI When:

• Cost is a priority — 30-50% cheaper for same models
• Building video features — Best video model selection
• Need speed — Faster inference times
• Want the latest models — Often first to add new models

Choose Replicate When:

For TeamDay Users

Both FAL.AI and Replicate work with TeamDay's visual AI skills:

Image Generation Skill:

# Uses FAL.AI by default (recommended)
bun .claude/skills/generate-image/scripts/generate-image.ts "your prompt" output.webp

# Or specify Replicate
bun .claude/skills/generate-image/scripts/generate-image-replicate.ts "your prompt" output.webp

Video Generation Skill:

# Uses FAL.AI (Kling 2.6 Pro)
bun .claude/skills/image-to-video/scripts/image-to-video.ts --image source.png --prompt "animate this"

Bottom Line

Our recommendation: Start with FAL.AI for most projects. The cost savings and model selection make it the better choice for production applications. Use Replicate if you need specific community models or prefer their documentation style.
