Overview
PoolTool is a free Cardano stake pool explorer that helps ADA holders compare pools and watch what the network is doing in real time. Browse every active pool, sort by fees and rewards, and bookmark favourites. Pool operators use the same site to monitor block production and see how their pool stacks up against everyone else.
PoolTool started life during Cardano's first staking trials, built by Mike Fullman (known in the community as papacarp) as a personal tool to track which pools were producing blocks. It grew into one of the most referenced staking tools in the Cardano world and is recognised as an official Cardano entity on cardano.org. The team also runs the LOVE stake pool.12
The site shows pool fees, how much each operator has staked themselves, blocks produced, and a two-month rewards rate, plus a live feed of new blocks and a dashboard for the health of the wider network. A free iPhone and iPad app delivers the same data on the go with push notifications.
Key Features
- Sortable pool list. Every active Cardano pool is listed with fees, the operator's own stake, blocks produced this round, blocks produced overall, and a two-month rewards rate. Click any column to sort the table1.
- Live block feed. A real-time view shows every new block as it is produced, with the pool ticker, how long it took to spread across the network, and how many other nodes are reporting it1.
- Network health dashboard. PoolTool collects voluntary updates from pool operators to show how quickly blocks are reaching everyone, what software versions pools are running, and where the relay servers are around the world3.
- Address lookup. Paste a stake address and PoolTool will show that wallet's rewards history and how it has performed over time1.
- Free iPhone app with alerts. The PoolTool mobile app sends a push notification when your pool produces a block, changes fees, or fills up. Rewards summaries arrive automatically each cycle4.
What to Expect
PoolTool opens straight to the pool list: a long sortable table on a dark navy background. Click any pool to see its full history, the list of delegators, and reward charts over time. The realtime tab refreshes with every new block, which is genuinely fun to watch, and the network health page packs a lot of charts onto a single scrolling page.
There is no account to create just to browse the data. PoolTool runs as a single-page web app, so JavaScript needs to be on, but otherwise it works in any modern browser. The site favours dense data over a polished design, which is exactly what people running pools tend to want. For delegators picking a pool, PoolTool gives one of the most complete views available among Cardano stake pool explorers, and pool operators rely on its block timing and network health charts that other explorers do not match.
