As answered by people managing Sangathan.space and Cert Decoder.
Sangathan.space's answer
Sangathan was created from a practical observation: organizations often have strong communities and ideas but lack the digital infrastructure to coordinate them effectively. Their work gets fragmented across messaging apps, spreadsheets, forms and disconnected tools, so Sangathan was built as a single operating system for organizing people, coordinating action and managing collective work.
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.
Sangathan.space's answer
Sangathan is built using modern web technologies including Next.js, React, TypeScript and Supabase for its backend infrastructure, database and authentication. The platform is designed as a mobile-first web application with a scalable architecture for organizations and communities.
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
Sangathan.space's answer
Sangathan is designed for NGOs, community organizations, citizen groups, student unions, worker unions, grassroots organizations, social movements and other collective organizations that need to manage members, coordinate activities and make decisions together.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Sangathan.space's answer
Sangathan is built for organizations that need more than a CRM or communication tool. It brings the core workflows of organizing into one accessible platform, reducing dependence on disconnected WhatsApp groups, spreadsheets, forms and multiple software subscriptions, while keeping the experience simple and mobile-first.
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.
Sangathan.space's answer
Sangathan is currently in its early product and adoption stage and does not yet have publicly announced enterprise customers. We are focused on onboarding early organizations, communities and grassroots teams and using their feedback to improve the platform.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Sangathan.space's answer
Sangathan combines organization management, member coordination, campaigns, mobilization, audits, resources, polls and collective decision-making in one mobile-first platform. Unlike general-purpose communication or CRM tools, it is designed specifically around how communities, NGOs, unions and grassroots organizations organize and operate.

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
