Built for the agentic era

Deploy in minutes

Single binary, no dependencies. Install on your machine and connect to live data with zero infrastructure overhead.

Read-only by default

Your AI can analyze and find patterns, but it cannot alter your original data unless you explicitly allow it.

CLI & MCP

Integrate with any AI agent via the command line or Model Context Protocol. Works with Claude, ChatGPT, Gemini, and more.

Zero ETL

No pipelines. No staging tables. No warehouse. Query your data exactly where it lives — in real time.

Cross-source queries

JOIN a PostgreSQL table with a CSV file and a Google Sheet in a single SQL query. PlyDB handles the federation.

Open source

Apache 2.0 licensed. No vendor lock-in, full transparency, and a growing community of contributors.


Supported data sources

One relational interface across databases, flat files, object storage, and SaaS platforms.

From chatbot to strategic partner

When your AI agent has a secure, real-time view of your data, it can answer complex questions the moment you ask them.

Sales

Strategic Sales & Retention

"Analyze our top 20 accounts by revenue. Cross-reference their support tickets with recent product usage. Generate a churn-risk dashboard and draft personalized outreach for the three accounts with the lowest activity."

RevOps

Revenue Operations

"Audit our active seat counts against signed contracts in the Google Sheet. Identify all overages, calculate the total unbilled revenue, and build a summary table the billing team can use to issue invoices."

Executive

Executive Insights

"Pull the MRR from the CRM, infrastructure costs from our logs, and headcount from the HR spreadsheet. Build a financial health dashboard and suggest three areas where we can improve our operating margin."

DevOps

Incident Response

"Review our app logs in S3 for errors from the past week. Cross-reference with our codebase and database replica to identify affected customers and diagnose root causes. Open PRs with fixes for the most severe issues, and draft a summary our PM and CSM teams can use."
