Workflows for AI coding agents

From prompt to production in under 60 seconds

Out-of-the-box tools to build real-time data pipelines.
20M rows/sec ingest. Sub-10ms queries. One prompt to deploy.

Get started with coding agents
Load FX, CFD, and Metals data from Oanda, create materialized views, and run analytics directly from the agent, with zero manual code.
# Give your AI coding agent the ability to build and deploy entire workflows with QuestDB.

The open data stack

Agents need answers, fast

The application layer is fragmenting into agents. The data layer is consolidating into open formats. QuestDB is the system of record that bridges both with astonishing speed and AI-native infra.

Single source of ground truth

Ingest real-time or historic data from any source. Every agent and application queries the same data for instant answers and insight.

Every tool connects

No proprietary protocols. No vendor SDKs. QuestDB exposes standard interfaces so your existing stack just works.

From vertical stacks to shared data

The old model: monolithic applications with embedded databases. The new model: composable agents querying a shared system of record.

Standard SQL. no lock in.
Easy to write SQL, powerfully extended for time series
Describe what you need. The agent discovers the schema, writes optimized SQL, and returns answers in milliseconds.

Supercharge Agentic workflows

We built the database an AI would design for itself.

Agents don't need raw data or dashboards, they need answers. Prompt to insight in milliseconds. Join thousands of developers already shipping on QuestDB, and help us define what agent-native infrastructure looks like.

Built for speed, scale, and Openness

Why developers and agents choose QuestDB

You need a database that handles 8M rows/sec ingest, answers queries in under 10ms, and speaks the language your agents already know. QuestDB is the time-series engine built for agentic workloads.

Open formats & full data portability

Any LLM or model framework can plug in seamlessly.

SQL. PGwire. REST. Parquet. Iceberg. Arrow. Every LLM and model framework already speaks these. No adapters, no wrappers, no translation layer.

AI Native infrastructure

Engineered to handle high volume concurrent queries from apps and agents.

Agents query and write to the same time-series backbone. Timestamp-ordered, no locking. Architecture that handles concurrent agent workloads by design.

Query billions of rows in milliseconds

Rows processed graphic

Custom query engine with vectorized execution delivers sub-millisecond latency. Memory-mapped architecture eliminates I/O bottlenecks, so queries run at CPU speed, not storage speed.

Auditable by default

Auditable query visualization

Every agent query is SQL. Every result is deterministic. No black-box reasoning, just timestamps, tables, and traceable logic. When compliance asks how the agent reached its conclusion, you show them the query.
