The short version

  • Both are free.
  • Only Directual lists visual database designer; only QuestDB lists high Throughput Ingestion.
  • Where Directual falls short: self-hosting is confined to the top commercial tier, so the ownership advantage is available only to buyers already spending at the high end.
  • Where QuestDB falls short: open-source edition lacks high-availability, distributed architecture, and enterprise security features.
  • Prices and features on this page were last checked on 13 November 2026.

What people use each for

The jobs each tool is most often brought in to do.

Directual

  • Providing the backend for a Webflow or FlutterFlow front end that needs real data, authentication and logicnot QuestDB
  • Replacing an Airtable base that has outgrown its row limits without hiring a backend developernot QuestDB
  • Event-driven workflows such as order processing or scheduled billing runs that must run without a person triggering themnot QuestDB

  • Real-time dashboarding with 32ms time-to-first-row latency for minute-level analyticsnot Directual
  • Applications requiring multi-tier storage (hot ingest, real-time SQL, cold Parquet archive)not Directual

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Directual

  • The front-end builder is basic, so any project needing a designed interface means learning and paying for a second tool, and time to launch is closer to a two-system build than a one-tool build
  • Visual scenarios become unreadable once the logic is non-trivial; a workflow that would be forty lines of code sprawls across a canvas, and reviewing what a colleague built is slow
  • Debugging asynchronous, event-triggered scenarios is harder than debugging code, because failures surface as records left in an unexpected state rather than as a stack trace at the point of failure
  • Self-hosting is confined to the top commercial tier, so the ownership advantage is available only to buyers already spending at the high end
  • The pool of agencies and freelancers who know Directual is small next to Bubble or Airtable, so handing a finished system to someone else to maintain is harder and more expensive

QuestDB

  • Open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • Enterprise edition pricing not published; requires contacting sales for custom quote
  • Ingestion limit of 20M rows/sec platform-dependent; may not scale to extreme throughput requirements

Answered from the vendors’ own pages

Directual: Is Directual a replacement for Bubble?

Not directly. Bubble builds the whole application; Directual builds the backend and expects you to bring a front end such as Webflow or FlutterFlow.

QuestDB: How much does QuestDB Enterprise cost?

QuestDB does not publish specific pricing for the Enterprise tier. Customers must contact QuestDB via their enterprise contact form to receive a custom quote.

Source
Directual: Can I host it myself?

Yes, on the top commercial tier. That is unusual in no-code and it is the main reason regulated buyers look at it at all.

QuestDB: Does QuestDB offer a free version?

Yes, QuestDB Open Source is completely free and recommended for evaluation, prototyping, and pilot projects. Enterprise features, high availability, security, and dedicated support require the paid Enterprise tier.

Source
Directual: How does it cope with large data volumes?

It is built on a real database with indexing rather than a spreadsheet abstraction, so record counts that break Airtable-class tools are within its normal range.

QuestDB: What deployment options does QuestDB offer?

QuestDB offers open source deployment, Enterprise deployment, and Bring Your Own Cloud (BYOC) deployment. Pricing details for BYOC and Enterprise tiers are not published and require direct contact with sales.

Source
Directual: What happens to my logic if I leave?

The data exports and the API is documented, but scenarios are platform-specific and have to be reimplemented, unless you are already on the self-hosted tier.
