I think I will ship a free open-source messenger with end-to-end encryption soon.

With zero maintenance cost, it’ll be awesome to watch it grow and become popular or remain unknown and become an everlasting portfolio project.

So I created Heroku account with free NodeJS dyno ($0/mo), set up UptimeRobot for it to not fall asleep ($0/mo), plugged in MongoDB (around 700mb for free) and Redis for api rate limiting (30 mb of ram for free, enough if I’m going to purge the whole database each three seconds, and there’ll be only api hit counters), set up GitHub auto deployment.

So, backend will be in nodejs, cryptico will manage private/public keys stuff, express will be responsible for api, I also decided to plug in Helmet and Sqreen, just to be sure.

Actual data will be stored in mongo, rate limit counters – in redis.

Frontend will probably be implemented in React, hosted for free at GitHub pages. I also can attach a custom domain there, let’s see if I can attach it to Freenom garbage.

So, here we go, starting up modern nosql-nodejs-react application completely for free.

If it blasts off, I’m moving to Clojure + Cassandra for backend.

And the last thing. It’ll be end-to-end encrypted. That means if it blasts off, it will probably attract evil russian government. They’ll want me to give him keys. It’ll be impossible, you know. But they doesn’t accept that answer. So if I accidentally stop posting there, please tell my girl that I love her and I’m probably dead or captured
