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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ottertune: open an issue to ask a question, or submit a pull request to add artifacts.
