Caspio: The Knack Alternative
A flat-priced database builder suits small databases. When records, storage, and compliance needs grow, teams outgrow the caps.
Caspio is an AI platform for building custom business applications and the Knack alternative for teams outgrowing capacity caps: a SQL Server data core built to scale to millions of records, annually certified HIPAA, SOC 2 Type II, and GDPR compliance, and unlimited users on every plan.
Scale That Is Not Priced in Caps
Knack is a flat-priced online database builder whose plans cap records, storage, and apps; growth is resolved by upgrading plans, and the ceilings are the pricing architecture itself. That suits small databases, and the caps can strain as data grows.
Caspio applications run on a SQL Server data core with role- and record-level security, built on more than two decades of platform engineering. Unlimited users come with every plan. The app that serves five people and the one that serves 5,000 run at the same platform price.
HIPAA That Is Published, Not Quote-Gated
Knack offers HIPAA through Knack Health, but per Knack's own plans documentation it is an Enterprise-level, contact-sales arrangement; standard and Plus plans are not HIPAA-eligible.
Caspio's HIPAA, SOC 2 Type II, and GDPR compliance controls are independently certified every year, and HIPAA coverage is available with every plan through a published compliance add-on. Caspio's HIPAA-eligible AI features operate under signed Business Associate Agreements (BAAs). Explore Caspio’s compliance posture on the Compliance hub.
24/7 Human Support on Every Plan
Knack's documented support hours are 8:00 AM to 8:00 PM Eastern, Monday through Friday, with paid customers' chat channel AI-powered and human email replies in 1 to 2 business days on lower plans.
Caspio provides 24/7 human support on every plan, handled by our in-house team. For organizations supporting users across time zones or outside business hours, around-the-clock support can be an important consideration.

Where Knack Is Strong, and Where It Strains
Knack earns credit for simplicity: flat published prices, unlimited app users on every plan, a quick start for small online databases, and, as of its April 2026 announcement, AI app building that extends to its HIPAA customers through Knack Health. The pairings sit in Knack’s own documentation: capacity ceilings on records, storage, and apps are the pricing architecture, HIPAA is an Enterprise-level, contact-sales arrangement rather than a published option, and support runs weekday hours with an AI-powered chat channel for paid customers.
Best for, Knack: Small online databases with modest record counts and no regulated data.
Caspio is designed for organizations whose applications continue to grow over time. It combines a SQL Server data core, annually certified HIPAA, SOC 2 Type II, and GDPR compliance available through a published add-on on every plan, four AI capabilities under one security model, and 24/7 human support. As requirements expand, teams can continue building without record-based plan ceilings.
Best for, Caspio: Teams that want AI app building and annually certified compliance on one platform, with unlimited users and room to scale at published prices.

Weighing the two from either side, the questions are the same: where the record and storage ceilings sit, which platform's HIPAA is published rather than quoted, and whether support is human around the clock. See why teams choose Caspio for the full comparison across platforms.
