Wasp is an open-source platform that acts as the glue between fragmented web development tools, compiling technologies such as React, Node.js and Prisma into one full-stack application. Founded by Matija and Martin Šošić and launched in 2021, Wasp is built as a layer on top of existing tooling so developers do not need to learn a new language or process. The platform detects common integration gaps (for example missing API keys) and suggests code changes to improve security and scalability, addressing risks from novice 'vibe coding.' Wasp can deploy to public cloud or enterprise servers and reports usage across numerous startups and Fortune 500 customers. The product entered beta in 2023 and has accumulated 26,000 GitHub stars. Financially, the company has raised $5.2M to date and says it will use new funding to focus on product development toward a v1.0 with features like multi-language support and server-side rendering. Wasp provides a simple configuration language and tooling layer that sits on top of existing stacks (React, Node.js) to speed up building full‑stack web applications. The product is open source and currently in alpha, available on GitHub. Founders Matija and Martin Sosic started the company in Croatia in 2019 and later joined Y Combinator (Winter 2021). Wasp reports about 300 apps have been built using the tool so far. The team is focused on improving the open‑source tooling before pursuing monetization. With the seed funding they plan to add features, reach beta, and ship version 1.0.
