PlanetScale

Neki is PlanetScale's sharded PostgreSQL product, built by the team behind Vitess. It uses explicit sharding to distribute PostgreSQL data and queries across multiple servers for demanding workloads. Neki is not a Vitess fork; PlanetScale says it was designed from first principles for PostgreSQL and was developed with large-scale design partners. The product was announced as available in Platform Preview.

Vitess is an open-source, cloud-native database system that provides a MySQL-compatible interface while extending MySQL for larger-scale deployments. Its built-in sharding routes application queries across shards without requiring sharding logic in the application; the video identifies VTGate as the intelligent proxy that parses MySQL queries and sends them to the appropriate shard, with sharding plans specified in a JSON VSchema file. Vitess also provides query rewriting, caching, connection pooling, materialized views, cross-shard messaging, live resharding, background schema changes, and automatic detection and repair of primary failures. It is a graduated Cloud Native Computing Foundation project.

Database Traffic Control is a PlanetScale feature for enforcing real-time resource budgets on Postgres query traffic. It matches workloads by query pattern, application name, Postgres user, or custom tags attached through SQL comments, then limits server share, burst capacity, per-query usage, or concurrency for each traffic slice. Budgets can run in warn mode to observe violations or enforce mode to block queries that exceed limits, with separate warning thresholds available for enforced budgets. It is designed for incident response, priority-based traffic shaping, protection against AI-agent traffic spikes, tenant and regional isolation, and safe deployment rollbacks. The feature is available for PlanetScale Postgres databases through the dashboard, API, and CLI, and integrates with PlanetScale Insights for finding problematic queries.

PostgreSQL is an open-source relational database management system maintained by the PostgreSQL Global Development Group. It provides SQL-compliant, ACID transactions, MVCC concurrency, and extensibility through custom types, functions and extensions, and is used for general-purpose and enterprise database workloads.

CapRover is an open-source, self-hosted platform as a service and web-server manager for deploying applications, databases, and websites on a user's own server. It provides a web GUI and CLI for managing deployments and supports applications built with Node.js, Python, PHP, ASP.NET, Ruby, and Go, along with databases and services such as MariaDB, MySQL, MongoDB, PostgreSQL, and WordPress. Under the interface, CapRover uses Docker and Docker Swarm for containerization and clustering, Nginx for customizable load balancing, and Let's Encrypt for SSL certificate management. It is designed to handle deployment and server-management tasks without requiring direct Docker or Nginx configuration, and the project states that applications continue working if CapRover is removed.
