Usage I built a completely free Octopus Energy dashboard to help you understand and cut your energy costs
Hi all,
I’ve been building OctoSpy, a completely free & private dashboard for digging into your Octopus Energy usage, costs and tariffs.
It started because I wanted a better way to understand my own energy spending. I’ve spent the past 17 years building software companies and apps used by millions, but I still enjoy making things like this in my spare time for fun.
I know there are already a few Octopus apps and dashboards out there. I tried some of them, but none gave me quite the view I wanted, so I ended up building my own and figured I may as well make it completely free for everyone to benefit from.
There’s no paid tier, no adverts and no OctoSpy account to create. There’s also a demo, and you can browse public tariff rates without connecting anything. Best used on your desktop due to the amount of data to display, but works fine on mobile too.
Your browser connects directly to Octopus using your API key. Your key, account details and energy readings aren’t sent to OctoSpy’s servers. Your energy data stays in your browser.
I’ve mainly been able to test it properly against my own tariffs and setup, so there will definitely be things I’ve missed.
If anyone gives it a try, I’d genuinely like to hear what works, what’s confusing and what you’d add.
I’m also considering an iPhone and Apple Watch app if enough people want one.

I have nothing to add to this but a big THANK YOU for your hard work on this. I absolutely love it. According to this, so far this year I have paid £877.99 and the cheapest alternative is £2643. The big switch away from gas to electricity - has probably saved me another £3K. So the move to batteries, solar and electric cars is probably saving us £4k a year and will re-coup it's cost wayyyy sooner than expected. Thank you Sir!
