Let Ottehr do the heavy lifting

Ottehr can reduce the time and cost of developing a custom EHR by 95%.

About Us

Ottehr is an open source EHR that began as part of Oystehr. After launching we realized that without an open-source EHR available as a starting point, releasing a custom EHR was still too difficult.

Ottehr is open to all, please submit feature requests or better yet, pull requests.  Our future EHRs will fork from Ottehr, and we hope yours will as well.
