## EverSQL

EverSQL has become one of the best-known online SQL tuning tools, trusted by over 100,000 professionals to make PostgreSQL and MySQL databases faster. 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

## Hex

Hex starts from a simple observation: dashboards tell you what happened, but they rarely answer the follow-up question. Its core is the Hex Agent, a conversational interface that plans a query, reasons over your organisation's context and returns an answer with the charts, tables and code that produced it. Because every answer is grounded in a semantic model and the underlying warehouse tables, users can inspect the SQL, check assumptions and trust the number before acting on it. The agent is reachable from the web workspace, from Slack, and from developer tools such as Claude and Codex via CLI and integrations.
Underneath the conversational layer sits a genuine notebook and app-building environment. Analysts write SQL, Python and R in the same project, chain cells into reproducible pipelines, and then turn selected cells into polished, parameterised data apps and dashboards that stakeholders can interact with. Hex 4.0 pushes this further with generative dashboards, AI app building and a Context Engine that keeps the company's definitions, metrics and semantics in one place. A Context Studio surfaces where the agent lacked grounding, and an Evals framework lets teams run graded test suites against the agent to measure accuracy over time.
That governance angle is what separates Hex from raw chat-with-your-data tools. Instead of an unsearchable answer in a side panel, you get a shareable, versionable artefact with lineage, plus a feedback loop that compounds context quality. It is used by data teams at a wide range of companies for self-serve exploration, executive reporting, embedded dashboards and operational analytics, with free, paid and enterprise tiers covering individuals through to regulated organisations needing SSO and advanced security.

**Pricing & Plans:** Freemium with a free tier to get started, paid plans for growing teams, and enterprise pricing (quoted on request) that adds governance, SSO and advanced security. A free trial is available for paid tiers.

- **Conversational Hex Agent:** Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
- **Notebooks and app builder:** Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
- **Context Engine and Context Studio:** Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
- **Evals for agent accuracy:** Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
- **Generative dashboards and governance:** Produce dashboards from natural language, embed them where teams work, and manage access with enterprise-grade permissions and security.

**Strengths:** Unifies exploration, notebooks, dashboards and app building so teams stop paying for four overlapping tools; Answers are grounded in a semantic model and warehouse tables, and stay inspectable rather than opaque; Slack, CLI and developer-tool integrations meet users where they already work; Context Studio and Evals turn context quality into something measurable and improvable

**Limitations:** The full value depends on having a reasonably well-modelled warehouse, so it is heavier to adopt than a simple chat tool; The notebook-plus-agent surface is feature-rich enough to need onboarding for non-technical users; Governance and advanced security features are reserved for higher-priced and enterprise plans
