Instead of hiring a dedicated DBA or manually reading through query plans and forum posts, engineers can submit a query and receive optimized SQL with clear, human-readable explanations of every change. The service is 100% non-intrusive and never accesses sensitive data inside your database. Beyond one-off query rewrites, EverSQL adds a lightweight performance sensor that continuously monitors your database. The sensor surfaces ongoing optimization insights, flags redundant or missing indexes, and highlights schema changes that reduce CPU, memory, and storage costs. This turns SQL tuning from a reactive troubleshooting chore into a proactive, ongoing practice. EverSQL is now part of Aiven, and free query optimization is available through the Aiven platform. Because it works across cloud, self-hosted, and managed deployments and does not require deep database access, it fits teams of any size. Customers commonly report queries running 25x faster within minutes of getting started, while teams reclaim dozens of hours previously spent on manual tuning. **Pricing & Plans:** Freemium with a free tier and paid plans. Free online query optimization is available, and EverSQL is now offered through Aiven with a free entry point; paid tiers and enterprise/contact-for-pricing options add ongoing monitoring and higher limits. Check the site for current tiers. - **Automatic query rewriting:** AI algorithms rewrite and re-index slow PostgreSQL and MySQL queries, then explain precisely which changes were made and how they improve performance. - **Ongoing performance sensor:** A non-intrusive sensor continuously monitors your database and generates easy-to-read optimization insights you can act on immediately. - **Index and schema recommendations:** Detects redundant or missing indexes and suggests schema optimizations that lower CPU, memory, and storage usage. - **Cost reduction guidance:** Highlights recommendations that cut monthly database spend by removing waste and tightening schema design. - **Non-intrusive and private:** EverSQL never reads sensitive data inside your database, so tuning stays safe for production systems. **Strengths:** Fast, actionable query rewrites with clear explanations; Non-intrusive and safe for production databases; Ongoing monitoring in addition to one-off tuning; Backed by Aiven with a free entry point **Limitations:** Focused on PostgreSQL and MySQL rather than every database engine; Advanced monitoring tiers require a paid plan [Profile (Markdown)](https://openaitools.app/tool/eversql-com.md) ## Postgres Sandbox Postgres Sandbox, available at postgres.new, takes an idea that sounds unlikely and makes it work: a real PostgreSQL database running entirely inside your browser. It is built on PGlite, a full build of PostgreSQL compiled to WebAssembly, so there is nothing to install and no server to configure. The moment you start writing SQL, a new database is created for you automatically. Around that core it adds a set of tools for getting things done quickly. An AI assistant helps turn natural-language requests into SQL and to reason about queries, which is valuable when you are sketching a schema or exploring unfamiliar data. You can import CSV files and query them immediately, generate charts from results, and draw ER diagrams to see how tables relate. Because the engine is genuine Postgres, the SQL semantics match what you would get on a real server, which makes the sandbox a natural place to prototype schemas, test a tricky query, teach SQL, or experiment with semantic search and RAG-style retrieval. It is best understood as a fast, disposable workspace rather than persistent production infrastructure — data lives in the browser rather than on a managed database. **Pricing & Plans:** Free. Postgres Sandbox runs in the browser at no cost — there is no install, no account requirement mentioned and no paid tier advertised. Just open the page and a PostgreSQL database is created as you start writing SQL. - **Instant in-browser Postgres:** A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration. - **AI SQL generation:** An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work. - **CSV import:** Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration. - **Charts and ER diagrams:** Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace. - **Semantic search and RAG:** Explore RAG and semantic-search style workflows against your data, using the sandbox to prototype AI data features. - **Real Postgres semantics:** Because it is real PostgreSQL, SQL you write here behaves like SQL you write on a server, so results transfer. **Strengths:** Runs real PostgreSQL with no install or server setup; AI assistance lowers the learning curve for SQL; CSV import, charts, ER diagrams and semantic search in one place; Genuinely free and instant to try in the browser **Limitations:** Data lives in the browser session, so it is not a persistent production database; Persistent storage depends on browser/IndexedDB and can be cleared; Not a substitute for a managed Postgres server for real applications; AI-generated SQL should still be reviewed before running [Profile (Markdown)](https://openaitools.app/tool/postgres-sandbox.md) ## Frequently Asked Questions ### How do EverSQL and Postgres Sandbox compare in monthly traffic?
