OtterTune

OtterTune was a database optimization ("on autopilot") start-up spun out of Carnegie Mellon University's database research group, operating from roughly 2020 to 2024. It applied machine learning to automatically tune the configuration knobs of PostgreSQL and MySQL databases (including managed instances such as Amazon RDS and Aurora) to improve performance and reduce cost. The company shut down in 2024 and its homepage now states the company is defunct. Its public GitHub organization remains available with infrastructure and agent tooling (ot-agent, Helm chart, CloudFormation/Terraform templates). This API Evangelist profile was added as a portfolio-company lead of Accel and captures the residual public footprint of a now-inactive company rather than a live API surface.

OtterTune is profiled on the APIs.io network. Tagged areas include Company, Big Data, Database, Database Optimization, and Machine Learning.
