OikoSearch is a free map of Switzerland that answers the question most tools avoid: once tax, rent and health insurance are paid, how much is actually left each month?

Cost-of-living sites give you an index or crowdsourced averages. OikoSearch estimates the monthly disposable income for a personalised household profile (income, family situation) across all 2,107 Swiss municipalities, on four concrete pillars:

Tax โ€” communal and cantonal rates from official scales (FTA/ESTV). Rent โ€” estimated rents by dwelling size (Federal Statistical Office). Health insurance โ€” actual LAMal reference premiums (FOPH). Quality of life โ€” 18 filterable criteria (transport, schools, healthcare, nature, shops), up to 44 shown per municipality. Every figure carries its source and year. When an official number isn't available, OikoSearch says so and flags the value as an estimate rather than inventing precision: the detailed cantonal tax bracket is currently verified for 4 cantons (~58% of the population), the rest use an explicitly signalled approximation.

Pick your profile and the map recolours to show where your money goes furthest, or compare candidate municipalities side by side. No account, no paywall, no tracking wall.

Built solo from public Swiss open data. Ideal for expats planning a move, residents weighing a relocation, and the FIRE community chasing financial breathing room in Switzerland.

Free. No signup. Available in French, English, German and Italian.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

  • Free & multilingual
    Completely free, no signup, no paywall. Available in French, English, German and Italian.

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Analysis of OikoSearch

Overall verdict

  • OikoSearch appears to be a Swiss-focused real estate search platform that aggregates property listings, offering a useful tool for those looking to buy or rent in Switzerland, though its overall quality depends on listing coverage, update frequency, and user experience compared to established competitors.

Why this product is good

  • Aggregates listings from multiple sources, saving users time compared to checking individual sites
  • Focused on the Swiss property market, potentially offering more relevant local search filters
  • Likely offers a simplified interface for browsing rental and purchase listings
  • May include useful search filters like location, price range, and property type

Recommended for

  • People searching for apartments or houses to rent or buy in Switzerland
  • Users who prefer aggregated search over checking multiple individual real estate sites
  • Expats or newcomers to Switzerland needing a straightforward property search tool
  • Budget-conscious renters or buyers comparing multiple listings quickly

Questions & Answers

As answered by people managing React Engine and OikoSearch.

Who are some of the biggest customers of your product?

OikoSearch's answer:

Free public tool โ€” individual users across Switzerland (no enterprise customers)

What makes your product unique?

OikoSearch's answer:

Most cost-of-living tools give you an index or crowdsourced averages. OikoSearch computes a personalised, municipality-level estimate of disposable income โ€” what's actually left after tax, the LAMal health premium and rent โ€” for all 2,107 Swiss municipalities, using only official government data. Its defining trait is radical transparency: every number is sourced and dated, and estimates are explicitly flagged rather than disguised as precision.

Why should a person choose your product over its competitors?

OikoSearch's answer:

Because it answers the real question โ€” "where can I actually afford to live in Switzerland?" โ€” rather than showing a generic index. It works at the municipal level (where the real gaps happen, not the cantonal average), it's built on official sources (FSO, FTA, FOPH, Swisstopo) instead of crowdsourced numbers, and it's honest about its limits. Free, no account, no tracking wall โ€” you can try it in seconds.

How would you describe the primary audience of your product?

OikoSearch's answer:

People making a concrete relocation decision in Switzerland: newcomers and expats planning a move, residents weighing a change of municipality, and the FIRE / financial-independence community optimising purchasing power. Secondary: data journalists and civic-minded users interested in communal tax and cost-of-living disparities.

What's the story behind your product?

OikoSearch's answer:

Built solo by a french developer in Switzerland, out of a simple observation: with the same salary, take-home money can differ by 2,000+ CHF/month depending on which municipality you live in โ€” yet no free tool made that visible at the municipal level. OikoSearch maps all 2,107 municipalities from official open data, with sources shown and estimates flagged, so anyone can see where their money goes furthest.

Which are the primary technologies used for building your product?

OikoSearch's answer:

Next.js (React, SSR/ISR) with TypeScript and TailwindCSS on the frontend; Leaflet + MapTiler for the interactive map; a Node.js/Express API backed by MongoDB. Hosted on Vercel (frontend) and Render (API). Privacy-friendly analytics via Umami (cookieless).
