Built my own visual API builder because I needed more than mock endpoints

Hey devs,

So I've been building side projects for a while, and I kept hitting this annoying pattern. I'd need a quick backend API - nothing fancy, just something to transform data, chain a few API calls, maybe query a data table.

But every time, I'd end up writing the same boilerplate: set up Express, add auth, handle errors, deploy somewhere, configure rate limiting... you know the drill.

I was using Beeceptor for mocking APIs during development (great tool btw), but I kept thinking "what if this could actually run real logic?" Like, what if I could just drag some components together and have a production API ready in minutes?

I am a novice builder, so my code is basically a combination of a few reusable code blocks I copy-paste from one file to another.

That's how I ended up building CFFBRW (www.cffbrw.com). Started as a weekend project to scratch my own itch.

Here's what it does - you drag components (Fetch, Filter, Loop, Aggregate, etc.) into a workflow, configure them, and boom - you get a real API endpoint. No servers to manage, auth, and rate limiting (😉 cannot get Cloudflare Ratelimit to work) built in.

Example: I needed an API that fetches crypto prices and calculates average changes. Instead of spinning up a Node server, I just:

1. Dragged a Fetch component, pointed it to CoinGecko API


2. Added an Aggregate component to calculate averages


3. Hit deploy

And got this endpoint in ~2 minutes:

curl -X POST 'https://api.cffbrw.com/v1/trigger/opensocialforall591b/averagePriceAndMarketcapChangePercentage24hTop5Cryptos'

Another one I use daily - filtering product catalogs from CSV:

curl -X POST "https://api.cffbrw.com/v1/trigger/opensocialforall591b/filterCatalogByCategory?category={{category}}"

The workflow is just: CSV component → Filter component. That's it. I also add JSONata to make it more flexible.

I've been using it for all sorts of random stuff:

• Quick data transformations for client projects


• Webhook receivers that actually process data


• API aggregators (hitting multiple endpoints and combining results)


• CSV to JSON APIs for static data query for my minisite.

Is it perfect? Nah. Still working on error handling, better debugging, and few more components. But it's been super useful for getting MVPs out fast. No more "let me just set up a quick Express server" that takes 2 hours.

If you're tired of writing boilerplate for simple APIs, give it a try. Would love feedback from other devs - what components would you want? What workflows would you build?

Currently free while I figure things out. Just trying to make something useful for developers like me who want to ship fast without the DevOps overhead.

Cheers!

P/S: oh maybe join me! I am nothing but a "vibe" (oh I hate this word) learner.
