As answered by people managing OikoSearch and Cert Decoder.
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 — 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.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
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).
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
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.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
OikoSearch's answer
Because it answers the real question — "where can I actually afford to live in Switzerland?" — 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 — you can try it in seconds.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
OikoSearch's answer
Free public tool — individual users across Switzerland (no enterprise customers)
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
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 — what's actually left after tax, the LAMal health premium and rent — 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? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
