QuestDB

What it is for

QuestDB is an open-source time-series SQL desk: you open the web console, and the Apache-2.0 license is $0. Use it when the job is ingest-and-chart SQL you start at $0 on your host, not when you need a $20 chat seat.

What makes it unique: the cover is the official QuestDB console (FX Technical Analysis OHLC, SQL pane, 2.7 billion rows) from the docs still — not a pricing card. The chart itself is ops of Queries. QuestDB Cloud / Enterprise is not a public $ tile on the pages we fetched (/pricing redirects to Enterprise).

Key features

• Web console / queries — a SQL + chart you run (console still; docs). One question. Cover OHLC, SMA, VWAP, and the SQL pane are ops of this.
• Tables — a time-series table you ingest into (cover Tables tree; docs). A table, not a query. trades / core_price on the cover sit here.
• Ingestion — ILP / Postgres wire you write (docs). A write path, not a chart. Cover “2,735,796,213 rows” is this meter.
• Materialized views — a maintained aggregate (cover Materialized views; docs). A view, not a table. Sample-by queries sit on Queries.
• Self-host / Enterprise — the Apache-2.0 binary you run vs Enterprise (LICENSE; Enterprise). A control plane, not a console. $0 is the license. Enterprise is Talk / trial — do not invent an Enterprise dollar.

Postgres wire and ILP clients are install. “Ask AI” on the cover is generate-on-Queries.

Who it's for

Best fit: teams who will stay on the Apache self-host at $0 while they open a first console chart, then talk to QuestDB about Enterprise because /pricing does not print a Cloud $ tile.

Pricing

Verified 2026-10-23 (Asia/Shanghai) from the Apache License 2.0 and questdb.com/enterprise (the /pricing URL redirected here).

• Open Source (self-host) — $0. Apache-2.0. You run the binary + the web console. Confirmed by LICENSE.txt (“Apache License / Version 2.0”).
• Enterprise / Cloud — not offered as a public $ tile on the pages we fetched. “Free Enterprise Trial” and Live Demo print as CTAs. Do not invent a QuestDB Cloud dollar.

Confirm your own VM / object-storage bill; taxes follow that host.

Limitations / costs

• $0 is the license, not the ingest disk. 2.7B rows still cost storage.
• No public Cloud $. Do not copy a third-party monthly figure.
• A time-series SQL desk, not a Postgres extension. For Tiger Cloud hypertables see Timescale. For streaming SQL see Materialize.

Alternatives

• Timescale — time-series Postgres when you want printed Tiger Cloud $30 compute tiles, not QuestDB’s Apache console.
• ClickHouse — OLAP SQL when you want ClickHouse Cloud credits, not QuestDB ILP.
• Tinybird — analytics APIs when you want a published endpoint, not a local console.
