Software studio · Since 2009
We build our own technology. Then we build yours with it.
Skelpo is the studio behind Perry, the compiler that turns TypeScript into native apps, and Skelpo CMS, the lighter alternative to WordPress. We use both to ship apps, websites and games for our clients.
- Perry
- TypeScript to native, 11 platforms, MIT
- Skelpo CMS
- Headless CMS, MIT, runs this site
- Games
- Native games in TypeScript
- BareNodes

What we can build for you
Four areas, each backed by a product we develop and run ourselves.
Built with Perry
Native apps from one TypeScript codebase
iOS, Android, macOS, Windows, Linux and more from a single codebase, compiled to real native binaries. No Electron and no JavaScript runtime shipped inside your app.
Native app developmentBuilt with Skelpo CMS
Websites and shops your team can run
Custom-designed websites on a CMS without plugins to patch, and online shops on Shopware, WooCommerce or Medusa. We take care of hosting and maintenance.
Skelpo CMSBuilt with Perry and Bloom Engine
Games for every screen
We ship our own games on mobile, desktop, TV and web from one TypeScript codebase, and take on co-development, prototypes and ports for studios.
GamesProven with BareNodes
Blockchain infrastructure and smart contracts
Dedicated nodes, indexers and smart contracts on Ethereum and EVM chains, from the team that operates its own bare-metal node infrastructure.
BlockchainWhy owning the compiler matters
Most agencies depend on someone else’s framework and wait for someone else’s fix. We wrote the toolchain, so when your app needs something the platform does not offer yet, we can add it.
- 11
- target platforms from one codebase, from iOS and Android to Windows, Linux and the web
- ~330 KB
- for a compiled hello-world binary, with no Node.js at runtime
- MIT
- open source, so your project never depends on a closed tool

You work with the person who builds it
Skelpo is led by Ralph Küpper, creator of Perry and author of “Hands-On Swift 5 Microservices Development” (Packt). No account managers in between: the person you talk to is the person responsible for your software.
