OGam3r RSS Reader

The OGam3r RSS Reader will retrieve your ingame messages via RSS feed, and notify you of any events, such as spying or attacks on your planet.

You can check here to see how it looks and read more about it.

It would be nice to see some other features, like sending emails when you're being attacked, or status of production/research or similar. Or at least combine the author's other project, OGame Ninja Timer with this.

Of course, it's not free: you'll have to dish out $10 to use it for 3 months, so it may not look so appealing, but if this is something you've been looking for, you're welcome to check it out.
I can't try it out so I got no idea if and how exactly it works, so don't blame me if it turns out to be something you didn't expect. For any concerns you might have I recommend mailing the author and asking him.

Kovan's OGBot Modified

Since official Kovan's OGBot doesn't work anymore, you can download this modified bot which works with OGame 0.77c.
It has pretty much the same features, but also a number of new ones, including some which will hopefully make it harder for game operators to detect it.

You can find the changelog and some additional info on ondealfa.free.fr, or get support on Kovan's OGBot forums.

Since I stopped playing like 8 months ago (phew, so long), I haven't been much active as far as OGame is concerned, so I'm pretty much out of the loop on most of the things. Thanks to a kind reader that pointed my attention to this! Due to the lack of accounts I can't test if and how this customized OGbot works, but judging by the activity and support on OGBot forums it seems it works well. It's pretty simple when it comes to configuring it, and you should be pillaging thy fellow players for resources in no time.

ProxyWay - Find proxy servers for OGame

I wrote about using proxy servers to hide your multiaccounts before, but here's a tool that will make the process of finding fast and reliable proxy servers much easier.

ProxyWay provides anonymous surfing and allows you to hide/change IP address from the web sites you visit. You can easily configure different browsers/applications to work through ProxyWay, it doesn't matter if you like Firefox or some other browser, the configuration is simple. You can even play OGame in a browser, while in the same time some bot does all the work on a different account. I won't get much into details about how to set it up here, since there's an awesome guide on ProxyWay website.
ProxyWay can also make your multiple OGame accounts even harder to detect by GO's since it can filter out proxy servers by country, so it can actually seem like you're playing from the same country - but you have a different IP.

There's a free version of ProxyWay; it may not be the best or the prettiest software out there, but it does it's job.

(Thanks to James for the tip!)

OGame Automizer

OGame Automizer, as the author says, is a client for OGame with some automated tasks, but not yet a bot. Anything with automated tasks is a bot, no?
Supposedly it is undetectable, because unlike other bots, this one emulates your browser requests.

Features (can also be found on OGame Automizer forum):
- Sound alerts, with customized sounds upon receiving new messages, attacks etc.
- Production Statistics
- Fleet movements
- Production and fleet overview of all planets
- Automized invest
- Automized transport fleet sending
- Player database
- Integrated Internet Browser

It requires Java to work, so make sure you have it if you can't run this bot.
The instructions can be found on OGame Automizer's site (if you can't open the page, check back in a few hours. Hopefully the downtimes will be fixed soon).

(Thanks for the tip, Thomas!)

OGame Ninja Timer

OGame Ninja Timer is a rather simple tool which will make it easier to determine the exact time when you need to send your fleet or recyclers.

From the author's website:

In OGame, there is a technique called the ninja. This requires precise timing, and I got sick of looking at my watch, or missing the right time. So, I wrote a program to time it for me.

This utility will beep for 1 minute before you need to send your fleet, 15 seconds before you need to send your recyclers and 10 seconds before the enemy fleet arrives.

The time when it tells you to send your fleets are offset. The ninja fleet is offset by the time it needs to arrive plus 10 seconds. That way, there is plenty of time for the page to load fully and have your ninja arrive a few seconds before the enemy's attacking fleet. The recycler timer is offset by it's fleet time plus 30 seconds.

It could use some work, especially on the design part, but the important thing is that it works. So if you find it usefull, go ahead and download it.
