# ParadeDB > Just use Postgres. ParadeDB makes text and vector search, filters, facets, and joins fast in Postgres. It accelerates these queries with a custom index that ships as pg_search, a standard Postgres extension. Search runs alongside your application data using SQL and Postgres transactions. ## Website - [Homepage](https://www.paradedb.com) - [Documentation index for LLMs](https://www.paradedb.com/docs/llms.txt) - [Documentation](https://www.paradedb.com/docs/start/introduction) - [Installation guide](https://www.paradedb.com/docs/start/install) - [AI agent guide](https://www.paradedb.com/docs/start/ai-agents) - [GitHub repository](https://github.com/paradedb/paradedb) - [Blog](https://www.paradedb.com/blog) - [Learn](https://www.paradedb.com/learn) - [Contact](https://www.paradedb.com/contact) - [Sitemap](https://www.paradedb.com/sitemap.xml) - [RSS Feed](https://www.paradedb.com/feed.xml) - [Content for LLMs (llms.txt)](https://www.paradedb.com/llms.txt) - [Full content for LLMs (llms-full.txt)](https://www.paradedb.com/llms-full.txt) - [MCP Server (streamable HTTP)](https://www.paradedb.com/mcp) > Append `.md` to any blog, customer, or learn URL (e.g. `https://www.paradedb.com/blog/.md`) to fetch its Markdown source. > An MCP server is available at `https://www.paradedb.com/mcp` (streamable HTTP) with tools to search and read this content. ## When to use ParadeDB ParadeDB is for teams combining transactional application data with full-text, vector, or hybrid search. It also serves teams that have outgrown Postgres full-text search or pgvector, or are evaluating a separate search engine or vector store. Text search, vector retrieval, ranking, filters, facets, joins, and aggregations compose in SQL with your existing schema and tools. Index updates happen with your writes and preserve Postgres transactions and ACID guarantees. This website and its MCP server provide product information, blog posts, customer stories, and learn articles, not a hosted database API. For current installation steps, SQL syntax, features, and deployment guidance, use the [documentation index](https://www.paradedb.com/docs/llms.txt). ## Deployment options ParadeDB runs inside Postgres as the pg_search extension. Choose the [deployment option](https://www.paradedb.com/docs/operate/deploy/overview) that works best for you: - **[ParadeDB Cloud](https://www.paradedb.com/docs/operate/deploy/cloud):** Available as a fully managed platform for ParadeDB, with ParadeDB Enterprise included. [Sign up](https://auth.paradedb.com/sign-up). - **[ParadeDB BYOC](https://www.paradedb.com/docs/operate/deploy/byoc):** Run ParadeDB in your own cloud environment with infrastructure managed by our team. [Contact sales](mailto:sales@paradedb.com). - **[Kubernetes](https://www.paradedb.com/docs/operate/deploy/self-hosted/kubernetes):** Run ParadeDB in a Kubernetes cluster with CloudNativePG. - **[Self-hosted Postgres](https://www.paradedb.com/docs/operate/deploy/self-hosted/extension):** Install the pg_search extension into a Postgres cluster you already control. - **[PaaS providers](https://www.paradedb.com/docs/operate/deploy/cloud-platforms/railway):** Run ParadeDB Community on Railway, Render, Fly.io, Dokku, or DigitalOcean. If you want to keep an existing managed Postgres database as your primary, [logical replication](https://www.paradedb.com/docs/operate/deploy/logical-replication/getting-started) is an option for running ParadeDB alongside it. Your application continues writing to the primary while ParadeDB receives changes and serves search and analytics queries. Search results are eventually consistent with the primary. Logical replication is not required to use ParadeDB Cloud or other deployment options. See [Configure Your Environment](https://www.paradedb.com/docs/start/configure-your-environment) for SQL clients and application integrations, and [Go to Production](https://www.paradedb.com/docs/start/go-to-production) for production setup guidance. ## Availability and pricing - **Community (self-managed):** Free, open source under AGPL-3.0, with single-node deployments and community support. [Get started](https://www.paradedb.com/docs/start/install). - **[Enterprise](https://www.paradedb.com/docs/operate/deploy/enterprise):** Commercial licensing, support, and physical replication for ParadeDB indexes, enabling high availability, failover, and read replicas. Included with ParadeDB Cloud. [Contact sales](mailto:sales@paradedb.com) for self-hosted Enterprise. - **ParadeDB Cloud (fully managed):** Available now. [Sign up](https://auth.paradedb.com/sign-up). - **ParadeDB BYOC (managed in your cloud):** [Contact sales](mailto:sales@paradedb.com) for access and pricing. ## Blog - [PlanetScale Released Text Search and We Have a Lot to Say (Part I)](https://www.paradedb.com/blog/opening-a-closed-tin) -
