Knack

This Knack review covers what the no-code platform is used for, its key features, Knack pricing, how it handles user access and security, where it shines and falls short, and how it compares with other tools. Knack starts from data: you define tables and connections, then build pages, forms and reports on top of that relational database. The result is a web app that your team, your clients or your suppliers log in to. Knack was founded in 2010, so it is one of the older players among no-code app builders. It is aimed at small businesses and non-technical teams that have outgrown spreadsheets and need secure access for many users without paying per seat. Business leaders usually pick it when a customer portal or an operations tool has to go live fast and the user base will keep growing.

What is Knack used for?

Knack is used to build data-rich business applications without code. Typical apps are client portals, inventory management systems, CRMs, asset and equipment tracking, job and project tracking, member directories and approval workflows. Many teams start with spreadsheets, import them into Knack and turn the data into a custom app with logins and permissions.

The most common use case is the portal. A company gives each client, partner or supplier a login, and user roles decide which records each of those external users can see and edit. Because every plan includes unlimited users, a portal with hundreds of logins costs the same as one with ten. Internal tools follow the same pattern for teams: forms to capture data, tables and reports to review it, and workflow automation to move records through business processes.

Key features

Knack's features cover the full path from data to a working business app, so you create the database, the user access rules and the workflows in one platform instead of joining separate software.

• Relational database: tables with typed fields, one-to-many and many-to-many connections, formulas and validation. This data structure is what sets Knack apart from form builders.
• Pages, forms and views: a drag-and-drop builder for tables, lists, details, forms, calendars, maps and search. The Next-Gen builder, released in 2025, adds section-based layouts and inline editing.
• User management and roles: logins for team members, customers and other external users, with role-based permissions that control access per page and per record.
• Workflow automation: rules, conditional actions, email notifications and scheduled tasks. Scheduling is an add-on on the lower plans.
• Reporting: charts, pivot tables and summaries on top of the data, so users see live numbers instead of exported spreadsheets.
• AI App Builder: describe your process and Knack drafts the tables and pages; each plan includes monthly AI credits.
• Integrations and API: native integrations with 450+ systems, a REST API with daily call limits, plus custom CSS and JavaScript for extra functionality.
• E-commerce and payments: checkout on the Pro plan and higher.

Knack pricing

Knack prices plans by records and storage, not by user. The figures below come from the Knack pricing page as of September 2026.

• Starter: $59 a month, or $49 a month billed annually. 20,000 records, 2 GB storage, 3 apps, basic SSO.
• Pro: $130 a month, or $110 billed annually. 50,000 records, 10 GB, unlimited apps, e-commerce, custom domain, two-factor login, maps and one month of record audit logs.
• Corporate: from $300 a month, or from $250 billed annually. 125,000 to 2.5 million records, 50 GB, advanced SSO, app restores and three custom domains.
• Enterprise: custom pricing for 2.5 million+ records, a dedicated account manager, HIPAA and GovCloud options.

New accounts get 66% off monthly plans for the first three months ($19 Starter, $49 Pro). There is a free trial without a credit card, but no free plan.

The cost surprise to check is the record limit. Unlimited users makes Knack cost effective for big portals, but a growing database pushes you into add-ons: 15,000 extra records with 5 GB cost $42 a month, 40,000 with 20 GB cost $90. Advanced SSO on Pro is a $55 add-on, and scheduling is $29. Count records and API calls before choosing a plan: the value of unlimited users only holds if your data fits the plan.

Build secure client portals with unlimited users

Knack is built for apps that external users log in to, so security sits at the center of the platform. Each app has user roles, and every page can be limited to certain roles; records can be filtered so that a client only sees their own company's data. Knack supports single sign-on, two-factor login on Pro and above, record audit logs, and HIPAA or GovCloud hosting on Enterprise. One point needs care: in multi-client apps, keeping each client's data apart is your job as the builder. Knack does not isolate tenants automatically, so set record rules for every role before you invite clients. For regulated data, the compliance features (audit logs, SSO, HIPAA hosting) sit on the higher plans, so check them on the pricing page before a customer signs.

Getting started with the Knack app builder

You create a Knack app in three steps. First, define the data: import a spreadsheet or let the AI App Builder draft tables, fields and connections for managing data such as customers, orders or assets. Second, build the interface: add pages with tables, forms, details and reports, and set which user roles can access each page. Third, add workflows: email rules, record actions and scheduled tasks that move data through your operations. The new interface of the Next-Gen builder lets you edit layouts inline, which speeds up editing compared with the classic builder. Most teams get a first working app in days, not weeks; complex permission rules and reporting take longer.

Is Knack the best no-code platform for small businesses?

For small businesses that run on data and logins, Knack is one of the most cost effective no-code platforms, because the price does not rise with every user. A company with ten staff and three hundred customers pays the same plan price as one with ten users. It is not the best no-code platform for every job: for native mobile apps, pixel-perfect design or large-scale SaaS products, other tools fit better. The value comes from the combination of an online database, role-based access, forms and workflows in one software package, with enough functionality for most customer-facing and internal business apps.

Where Knack shines — and where it falls short

Strengths:

• Unlimited users on every plan, which suits client portals and large teams.
• A real relational database with roles and record-level permissions.
• User friendly for non-technical teams who know spreadsheets, with no need for deep technical skills.
• A long track record, with over 5,000 organizations using it.

Trade-offs:

• Apps run in the browser; there are no native apps for the App Store or Google Play.
• Record limits and add-ons drive the price as data grows, even when users stay flat.
• Reporting and design are basic compared with BI tools and design-first builders.
• No offline mode, because apps need an internet connection.

How Knack compares

• Airtable: a flexible database with interfaces, priced per editor.
• Quickbase: enterprise no-code apps with more governance, at a higher price.
• Caspio: a similar online database builder with plans by data and apps.
• Softr: polished portals on top of Airtable, Google Sheets or its own database.
• Glide: mobile-friendly apps from spreadsheets, priced by users and updates.
• Bubble: pixel-level web apps and SaaS products, with a steeper learning curve.
• Claris FileMaker: a long-standing database platform with desktop and iPad apps.
• Ninox: a European online database with GDPR-friendly hosting.

Is Knack worth it?

Knack is worth it when you need to build secure apps on an online database with many logins: client portals, supplier portals and internal tools where per-seat pricing would be expensive. It is quick to learn for teams that know spreadsheets, and it handles data organization and user management better than most form or spreadsheet tools. It is less of a fit when you need native mobile apps, offline use, a polished custom design, or when your record count will grow into the millions without a matching budget. If you want help designing the data structure or building a portal, the low-code agencies and developers on LowCodeDevs can take it on.
