Tailwebs builds with Flutter, React Native, Android and iOS for mobile; Python, Node.js, Ruby on Rails and PHP for backends and web apps; and LLM integrations for AI features.

03 Pick by project

Pick by project, not by stack

Know what you are building, but not which technology fits? Find the row that sounds like your project.

New builds

  • The product's value is in processing data, scraping or reporting

    Python

  • Many users are connected at once and expect live updates

    Node.js

  • One codebase for both app stores, with a custom brand-led interface

    Flutter

  • Your web product or team already works in React or TypeScript

    React Native

  • The app depends on device hardware, background work, wearables or budget Android phones

    Android

  • The app depends on Apple-only features or in-app subscriptions

    iOS

  • A data-rich platform with admin review workflows, built to change for years

    Ruby on Rails

  • A content site your team edits every day

    PHP

  • Answers or extraction from your own documents

    AI and LLMs

Existing apps

  • An ageing Rails app, or one whose developers have moved on

    Ruby on Rails

    Read what a takeover and an upgrade involve.

  • A PHP or WordPress site on an old PHP version

    PHP

    Start with the version check on the page.

  • A React Native or Flutter app that is behind on versions

    Read the matching page on store releases: Google Play release on Android, App Store review on iOS.

04 Not sure?

Not sure? Start with discovery.

If more than one row fits, we pick the stack in a Discovery Sprint, based on your users, features, budget and the team who will maintain it.

  • The Discovery Sprint: ₹1.5–3 lakh, over 2–3 weeks.
  • What it covers: how the sprint runs, and what it hands over, is on product consulting.
  • After that: how a build runs, step by step, is on our process page.

05 FAQ

Questions about our technologies.

What technologies do you use?
We build with Flutter, React Native, Android and iOS for mobile; Python, Node.js, Ruby on Rails and PHP for backends and web apps; and LLM integrations for AI features.
Do you build native or cross-platform apps?
Both: we build native Android and iOS apps and cross-platform apps in Flutter or React Native, and settle which one during discovery.
How do you decide which technology to use for my project?
We decide in discovery, from your users, the features the app needs, your budget and who will maintain it; the Discovery Sprint takes 2–3 weeks.
Can you work on an app that's already built in one of these technologies?
The Python, Node.js, PHP, Ruby on Rails, Flutter and React Native pages explain what upgrading or taking over an existing app in that stack involves; the Android and iOS pages cover keeping an app current on the stores.A takeover starts with a code review of the app, its tests, its accounts and its store set-up.
Do you work in technologies not listed here?
Possibly. Tell us the technology, and we'll say in discovery whether we're the right team or another team would serve you better.
