It catches mistakes before launch, so your clients never see them, and the product stays easy to grow for years. Reliable code strict typing reduces the risk of bugs Enterprise ready from startups to complex platforms No. 1 on GitHub the most popular programming language in 2025 Proven by Microsoft, Slack and Airbnb run on it ![Clutch Global Award](https://synapseteam.com/img/clutch/global.svg) ![Clutch Champion, Spring 2024](https://synapseteam.com/img/clutch/champion-spring-2024.png) [Get an estimate](https://synapseteam.com/technologies/typescript/#contact) [See our works](https://synapseteam.com/technologies/typescript/#works) ## What is TypeScript? TypeScript is a strongly typed programming language from Microsoft built on JavaScript. Types are checked at build time, so whole classes of bugs show up before the code reaches users, and the output is plain JavaScript that runs anywhere. Synapse Team writes its projects in TypeScript, including the agency’s own website. ## What we build in TypeScript Pick the service that matches your project, or start the brief and we route it for you. 01 ### Websites Turnkey websites: interface, CMS and integrations in one language. [Websites](https://synapseteam.com/services/web-development/) 02 ### SaaS products Products where payments and client data are protected from errors. [SaaS products](https://synapseteam.com/services/saas-development/) 03 ### Custom software Dashboards, portals and tools that are easy to maintain. [Custom software](https://synapseteam.com/services/custom-software-development/) 04 ### Frontend development React and Astro interfaces in TypeScript. [Frontend development](https://synapseteam.com/services/frontend-development/) 05 ### MVP development A fast launch that is easy to grow after version one. [MVP development](https://synapseteam.com/services/mvp-development/) 06 ### Online stores Stores where checkout errors are caught before launch. [Online stores](https://synapseteam.com/services/ecommerce-development/) ## Why we default to TypeScript Types work as an agreement inside the team and with every integration. On every build the compiler checks the whole project, and that is exactly the safety net fast delivery needs. - Bugs are found during the build, not on the live site - Changes are safe: the compiler shows every place they touch - Clear data rules for APIs, the CMS and payments - Every change, including AI-assisted ones, is checked by types first, then by an engineer ## When we recommend something else Not every task needs TypeScript. Here is when we honestly recommend another option, and build it ourselves. - A small one-off script: plain JavaScript is enough - WordPress themes and plugins: the main language there is PHP - Laravel projects: we write them in PHP - A large older JavaScript project: we estimate the switch separately Technologies we build with [Astro](https://synapseteam.com/technologies/astro/) [Payload CMS](https://synapseteam.com/technologies/payload-cms/) [Next.js](https://synapseteam.com/technologies/nextjs/) [React](https://synapseteam.com/technologies/react/) [Vendure](https://synapseteam.com/technologies/vendure/) [Node.js](https://synapseteam.com/technologies/nodejs/) [WordPress](https://synapseteam.com/technologies/wordpress/) [Laravel](https://synapseteam.com/technologies/laravel/) ## AI-fast or classic: you choose the pace AI speeds up development, engineers guarantee quality: every change is checked automatically by types first, then by a senior engineer before release. Prefer a traditional process? We run that too, with the same quality bar. Option A ### Classic build Traditional cycle with the same team and quality gates. SaaS MVP in TypeScript from $10,000 · 10–12 weeks Option B up to 2× faster ### AI-powered build Fastest path to launch. AI speeds up the work, engineers verify every line. SaaS MVP in TypeScript from $4,000 · 4–6 weeks ## Pricing and timelines Landing page from $1,000 3–5 days Corporate website from $2,000 1–2 weeks Store with up to 50 products from $3,000 3–4 weeks AI chatbot or automation from $2,000 1–3 weeks Draft ranges.

TypeScript is JavaScript with a type system: the same language your browser runs, plus checks during the build. The compiler verifies the data before release and outputs plain JavaScript. The site runs and is hosted exactly the same way. ### How much does TypeScript development cost? The language does not change our pricing: - SaaS MVP in TypeScript: AI from $4,000 (4–6 weeks), classic from $10,000 (10–12 weeks). - Internal tool in TypeScript: AI from $4,000 (3–6 weeks), classic from $6,500 (6–10 weeks). Describe your project in the chat and the team sends a precise fixed-price estimate within one business day. ### Does TypeScript slow development down? A little slower at the start, faster every month after: changes stop breaking hidden places, new developers understand the project sooner, and reviews focus on logic instead of bug hunting. Types also filter out wrong changes automatically, including AI-assisted ones. ### Can you migrate an existing JavaScript project to TypeScript? Yes, and it can be gradual: TypeScript runs next to JavaScript in one project, so we move the riskiest parts first, payments and data handling, and the rest over time. The product keeps getting updates during the whole switch. ### What does TypeScript give me as a client? Fewer bugs on the live site, cheaper support and clear code that is easy to grow. It is one of the reasons we can commit to a fixed price and timeline.
