2019 Update: For everyone who is posting now, I have already bought a premium host a long time ago.

Amazon AWS will give you a year free of their most bottom tier EC2 server: https://aws.amazon.com/free/

Probably the best thing you'll be able to get for free by far.

Mayyyybe x10hosting, but I don't know if they'd allow those kind of bot scripts, if it would put stress on their servers.

Do you know any host that does not require a credit card and identity stuff.

I don't run my bot on their webhost.
All I need to do is let my bot add something to a mysql database.

I would just use Hostinger and make an API for the bot using PHP.
You would save time by not searching for new stuff, but using what you have at your disposal.

I'd recommend using c9. They provide MySQL (and postgres, if that's more your jam), PHP, Rails, Node.JS, and pretty much any other framework and language you'll ever need pre-installed. The hosting is fast and reliable, and the IDE itself is quite nice.

[Dismas]

I'd recommend one, except I don't recommend free hosts. You generally get what you pay for.

Have you tried 000webhost? Not sure if it's the same like Hostinger.

I would recommend x10 hosting too!

You can also give this a shot: http://www.uhostfull.com/free-hosting.php

Given It's free, you have nothing to lose and should It suffice, everything to gain.
