Plenario is retiring
Soon we will retire Plenario. We created Plenario 8 years ago to explore new ways to discover and evaluate open data. Today's open data portals extend such features and more! Thanks for being part of the journey.
One database. One map.
All data in Plenario exists on a single map and a single timeline, making it incredibly easy to access multiple datasets at once—especially those originally housed at different data portals.
Extremely easy to access.
No coding, no NDAs, no navigating government websites older than you are. Accessing the data is as easy as selecting dates and drawing on a map. (Don't worry, you can still code.)
Enormous variety of data.
City data portals, the federal government, individual datasets—we have it all, whether originally housed at Socrata or CKAN data portals or in CSV format.
Tell the story of place.
With all the data at your fingertips, you can watch places change over time.
Here’s an example: Get a week-by-week look at downtown Chicago since 2013.
Let’s build something bigger than all of us.
Plenario is fully open source, collaborative, extensible, and growing every day. It isn’t just a platform—it’s a community and a new way to think about open data.
