## 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

## Releem

Releem is a database performance advisor built for teams running production MySQL. Instead of relying on generic best-practice templates, it profiles your actual workload - query activity, configuration settings and resource metrics - and uses machine learning to recommend settings tuned to how your database really behaves. It covers MySQL as its primary target, with MariaDB, Percona Server and PostgreSQL also supported through the same interface.

The product spans the main levers of database performance. Query analytics highlights slow and expensive statements; the index advisor proposes indexes with explanations and ready-to-run SQL; schema optimization flags overlapping indexes that add storage and write overhead; and monitoring adds process list visibility, deadlock detection and security checks. Each recommendation comes with reasoning so you can prioritise, and every change can be measured against before-and-after query times and CPU usage.

Deployment is straightforward: create an account, install the open-source Releem Agent on the database host, and review recommendations. The agent needs no inbound ports and sends metrics over HTTPS without collecting table contents. Pricing is per database server with a free trial - Starter covers one server, Scale covers small fleets, Hosting targets providers and MSPs, and Business plans add custom terms, data residency and SLA options. Supported environments include Amazon RDS and Aurora, Google Cloud SQL, Azure, Linux, Windows, Docker and Kubernetes.

**Pricing & Plans:** Free trial available. Starter from $39/database server/month billed annually ($49 month-to-month), Scale $123/month for up to 5 servers, Hosting $99/month for up to 9 servers, and custom Business plans for larger deployments.

- **Configuration Tuning:** Machine-learning recommendations for MySQL settings based on your actual configuration and workload, with before-and-after comparison.
- **Query and Index Advisor:** Identifies slow and frequently executed queries, analyses existing indexes and proposes index improvements with clear SQL statements and explanations.
- **Schema Optimization:** Detects redundant, overlapping indexes and suggests removals with reasoning, helping cut storage and write overhead.
- **Monitoring and Health Checks:** Continuous monitoring, process list visibility, deadlock detection and health checks that surface performance and security findings.
- **Safe, Controlled Automation:** An open-source agent that collects metrics over HTTPS without inbound ports, with controlled automation for supported configuration and schema changes.

**Strengths:** Recommendations are based on your real workload, not generic templates; Explains each query, index and schema suggestion before you apply it; Supports MySQL, MariaDB, Percona Server and PostgreSQL from one tool; Open-source agent with no inbound ports and no collection of table contents

**Limitations:** Per-server pricing means large fleets need Scale, Hosting or Business terms; Full automation paths depend on your deployment and may need manual review; Some advanced items such as team management and SSO are still marked coming soon; As a cloud service it requires installing an agent on each database host
