InvisibleHand blog

Watch this space for the latest news about InvisibleHand project. We'll blog here about new retailers, new countries and new features.

InvisibleHand available for Google Chrome!

Today Google unveiled the official Chrome extensions website, so we uploaded InvisibleHand for Chrome there. It lacks many features that Firefox’s version has, mainly UK/Germany support (yes, it’s US only at the moment), but we’re working on it. Download InvisibleHand for Google Chrome now!

New website for InvisibleHand

We have just deployed a new website for InvisibleHand, which is easier to navigate and provides more information. Please feel free to let us know in the comments what you think about our new website.

In the meantime, we’re approaching $20 million savings in the US and are working hard on adding new countries and more retailers. We’ve just added a dozen German online shops with over 14 million product pages between them. Guess which country comes next on the list?

InvisibleHand Finds $10 Million of Savings for US Users

American users of InvisibleHand have used it to find savings of over $10 million so far. That’s a pretty impressive amount. For an idea of what that kind of money looks like, check out this nice visualisation

Roll on $100 million!

US servers are up again

Our US servers were experiencing problems for approximately 3 hours and 13 minutes today, so many notification were not shown during this period. The problem has just been fixed. UK users should not have been affected. Sorry for the inconvenience caused and thank you for your patience.

InvisibleHand Now Covers Zavvi

We hear you! We’ve been receiving requests for even more retailer coverage in InvisibleHand. Zavvi was top of the list, with its range of DVDs, music, games and electronics.

Keep an eye out in the coming weeks for lots more new retailers and products in InvisibleHand. InvisibleHand is going to become even more comprehensive!

Brief InvisibleHand Outage In US

InvisibleHand’s popularity has been putting a lot of strain on our servers. As a result there have been a few brief outages today during which US users will not have received price notifications. Our server gurus are working on the problem and normal service should be resumed very soon.

UK users are not affected.

In the mean time, please accept our apologies for any inconvenience caused.

UPDATE: The problem has been fixed. Everything should now be working as normal.

Everyone Loves InvisibleHand


It’s been a busy day for InvisibleHand. Top productivity blog, Lifehacker, reviewed it this morning. In the afternoon, Gizmodo claimed “I’m addicted to its unobtrusive deal-finding prowess”. And now thousands of new users are downloading InvisibleHand to automatically get the lowest prices on the web.

We’ve just had to update our homepage to prevent the stats counter from running out of space…

InvisibleHand is an Official Firefox Add-On


We’ve been waiting a while, but InvisibleHand is been officially approved by Mozilla and is fully listed on the Mozilla Add-Ons for Firefox website.

This is good news for everyone. You’ll receive automatic updates when we push out new versions, and it shows that InvisibleHand is a well-behaved add-on which will only do good things for you!

We’ve also been the recipient of a “100% clean” award from Softpedia. This guarantees that InvisibleHand does not contain any spyware, adware or viruses. Nice to know!

InvisibleHand Hits 1.0

It’s taken a while to get there, but we reached version 1.0 today!

The latest version of InvisibleHand supports a larger number of retailers (32) and products (erm… loads & loads) than before. Plus, you’ll now see a discreet notification when you’re browsing the cheapest retailer, confirming that you’ve already got the lowest price and letting you know other stores which sell the same item.

InvisibleHand 0.8 is out

We worked hard on improving our algorithms and adding support for more retailers to release InvisibleHand 0.8 that shows more notifications at a larger number of retailers across the US.
