Builder here. I made BTCDash because every dashboard I tried was paywalled, ad-covered, or wanted an account to show a price chart.
It's a single static page — everything loads client-side from ~30 public APIs (mempool.space, CoinMetrics, Binance, the US Treasury debt API…). No backend, no signup, no tracking beyond basic analytics. Your browser talks to the sources directly.
Things SN folks might actually use:
- Fee heatmap: median sat/vB by weekday × hour, in your timezone — find the cheap windows for consolidating UTXOs
- Halving countdown, hashrate/difficulty, miner economics, Lightning stats
- TV mode for a wall screen or spare monitor (with a last-block heartbeat)
- Stack tracker that lives entirely in localStorage — your stack never leaves your device
Free, stays free. Tell me what's missing — feature requests from this thread genuinely become next week's cards.

Are you taking suggestions? For tools? If so can you add a look up date and price. For example if I want to know the value of sats I sent to someone on July 6th 2024 at 4pm est?
It would be great to enter a date and a number of SATS to get the fiat equivalent at that time and the gain or loss since the txn date.
Great job dash board is robust!
I just published this earlier today: https://jon-hodl.github.io/bitcoin-time-machine/
It doesn't do what you're describing but it sounds like it's already a welcome feature.
If you have the txid of sending to your friend on July 6th 2024, you can look it up and get basic profit loss on it with some useful data.
I will see how I can integrate your idea.
Wow this is great! Thanks
Is this site collecting data?
Not that I know of. It queries mempool.space for the date of the tx and then uses my bitcoin price archive for the price data on that date.
Just added this feature.
You just have to select "Date & Sats"
Thank you!!!
🤝
Here can you add two more data metrics
fiat value now and fiat value then?
Also is it possible to add a bitcoin address and use the info from mempool.space to get info like TXN amounts transferred and current fiat value then and now of the UTXOs in the bitcoin address?
Done :)
Where?
scroll down to the tools tab "calculator", let me know if thats what you needed.
Hi, of course, happy to receive feedback. I think it is possible, let us work on this and add it to the tools tab. thanks!
How about a light mode?
sure, that's an easy change.
Nit: The number in the front here corresponds to the count of halvings, but I’d argue that the first epoch would be the 50 ₿-subsidy epoch which is omitted here. So, I’d either suggest renaming the title from "33 Epochs" to "34 Epochs" and add the first epoch, or to instead title it as 33 halvngs. :)
done :)
Thanks for spotting that, nice catch. We will correct it in the next update. :)
to be added tomorrow:
Less is more
noted. Check out TV mode, is more concise.
Wow!! That's a great one
