Executive Summary

Teams using schema-first generators (Prisma, GraphQL, OpenAPI) routinely hit tsserver crashes and long editor freezes from huge generated types, costing developer time and slowing reviews — this problem hits both startups and enterprises and is common enough to affect hundreds of thousands of developers. It’s a real productivity sink for maintainers of large TypeScript codebases and for teams that rely on fast editor feedback. You could build a lightweight codegen + LSP proxy that emits compact, semantically-equivalent type artifacts and intercepts language-server workloads so editors no longer need to load massive type trees; delivered as non-invasive editor extensions and build-time plugins, it would preserve TypeScript semantics while dramatically reducing tsserver memory/CPU usage. The timing is strong: TypeScript and schema-first workflows are mainstream, and the addressable market is roughly $4.5B (500K developer teams × $9K ACV), with clear willingness to pay for tooling that improves developer velocity and stability. The competitive edge is a non-breaking, LSP-level approach that can be adopted incrementally and avoids forking compilers or changing developer workflows, making it easier to sell into teams than heavy refactors. Major challenges are proving semantic equivalence across TypeScript releases, ensuring security/compatibility with diverse generators, and building the trust needed for enterprise adoption, but if you solve those you can capture a meaningful share of a medium-competition market.

Market Opportunity

Fix TypeScript/tsserver crashes from huge generated types with lightweight codegen targets a $4.5B = 500K developer teams × $9K ACV total addressable market with medium saturation and a year-over-year growth rate of 15% annual growth in developer tooling and observability markets (sources: SlashData, Stack Overflow industry reports and public devtools market analyses).

Key trends driving demand: TypeScript adoption continues to grow across startups and enterprises — as TypeScript use rises, tooling pain from heavy type generation becomes more common, creating demand for fixes.; Schema-first development (Prisma, GraphQL, OpenAPI) is mainstream, increasing the volume of generated types and the likelihood of tsserver issues.; Editor/IDE extension ecosystems and LSP proxies have matured, enabling non-invasive tools to interpose on language servers and improve performance without breaking type semantics..

Key competitors include Prisma, TypeScript / Microsoft (tsserver), GraphQL Code Generator.
