Yes. Our free trial will let you taste some of the optimization magic before you have to make the big decision. Once you run out of free credits, you can either subscribe to one of our plans, or invite some friends to join us and earn some more free credits.

Do you need any access to my database or data?

No, we do not require any access to your database, nor your sensitive data.

Which databases are supported?

We're currently focused on optimizing your experience with MySQL, MariaDB and Percona Server. Having said that, some of our recommendations may apply to other databases as well, but we can't promise nor support those at the moment. Feel free to contact us in case you need more information.

Why do I need to upload the schema's structure?

Optimizing SQL queries is a complex task, which usually requires several data sources to get it right. As much information as we'll have on your query, database and environment, the better recommendations we can offer. Therefore, providing the SQL query, schema structure, execution plan (EXPLAIN) and other information may be required, in order to fully utilize the power of EverSQL Query Optimizer.

Can I integrate database monitoring solutions to EverSQL?

Yes, you can. A list of supported database monitoring applications and installation instructions can be found on the integrations page.

What's the magic behind indexing recommendations?

We take indexing recommendations very seriously, as they are the foundation for good query performance. Therefore, we invest a lot in creating our proprietary algorithm, while constantly testing it on tens of thousands of real queries and databases. EverSQL's algorithm takes many factors into consideration to calculate the best indexes for your query. Among those factors are the query structure, table sizes, existing indexes and their cardinality, column types and sizes, the connections between the tables and columns in the query and many other factors. That said, we believe that there is no such thing "a perfect algorithm". Therefore, if you think we could do better with the recommendations we provided, please let us know.

How much does it cost?

Do you provide a desktop application / IDE plugins?

We get requests to provide a desktop application that connects to the database and pulls the relevant information on its own. Also, we are receiving user requests to provide our optimization product as a plugin to different SQL clients, such as SQLYog, MySQL Workbench, Navicat, PHPMyAdmin, Datagrip and others. If you enthusiastic about SQL performance and would like to see the desktop application or IDE addons released, please let us know (contacting us will help us decide which of these options to develop and release next).

Is the data sent on a secure channel?
