I built an OpenAPI-to-SDK generator that writes code like a human did in 7 languages, no lock-in.
Hi All,
My name is Venkat, solo-developer based in Keller,TX. I launched Ferrumlabs , an SDK generator that takes any OpenAPI spec and produces idiomatic, production-ready SDKs in 7 languages.
Why I built this: Stainless is great but priced for funded companies. Most startups just want clean, human-feeling SDKs without paying enterprise rates or jumping on a sales call. That's exactly who Ferrumlabs is for. No sales calls, no demos, bring your API file or link and get the sdk generated.
What you get:

My name is Venkat, solo developer based in Keller, TX. I just launched Ferrumlabs — an SDK generator that takes any OpenAPI spec and produces idiomatic, production-ready SDKs in 7 languages.

What you get:
Hand-written-feeling output, not machine-generated boilerplate
You own everything — no lock-in, no proprietary config
7 languages today, more on the roadmap
$0 MRR, day one. Building in public.
If you've ever needed SDKs for your API but couldn't justify Stainless pricing — Ferrumlabs is built for you. Would love your feedback.-feeling SDK output, not machine-generated boilerplate

Strong build, Venkat.
The angle I’d be careful with is letting Ferrumlabs get framed only as “Stainless but cheaper.”
That comparison helps people understand the category, but it can also trap the product in price comparison instead of the real pain: early API companies need clean SDKs fast without sales calls, enterprise pricing, or vendor lock-in.
The sharper first-user wedge is probably startups that already have an API, already know SDKs matter, but are delaying them because the current options feel too expensive or too heavy.
That is the segment I’d test before going broad.
Happy to put a tighter version in writing if useful. The useful part would be the first buyer segment, positioning angle, and the outreach path to get the first serious SDK generation users.
