Developer tools for founders
We make starter kits that give you a working SaaS app on day one, so you start from something real instead of an empty folder.
Who we are
KeyNLP Inc. is a small software company incorporated in Ontario, Canada. We build and sell FastSvelte and FastReact, two SaaS starter kits with sign-in, billing and AI usage tracking already set up. You pay once and get the full source code. We also help teams with consulting, custom software and AI features.
What we make
Both kits run on the same FastAPI backend. Pick the one that matches the frontend you already know.
Work with us
Need more than a starter kit? We also take on client work.
Consulting
A second pair of eyes on your project. We help with architecture, cloud setup, testing and deployment, and planning your next release.
Custom software development
We build SaaS apps and backends for you, from first version to production. Python, React and Svelte, deployed on AWS, Google Cloud or Azure.
AI and NLP
We add AI features to your product, like chat assistants, search over your own documents and pulling data out of text. Built on current language models, with usage costs kept in check.
