Knack Review (2026)

Builds online database applications with forms, roles and reports, aimed at organisations replacing a shared spreadsheet with something that has permissions.

The quick answer

Assessed for 2026

Unfashionable and quietly dependable. Knack has been building database applications for fifteen years and it shows in both directions: the data modelling and role handling are solid and it stayed up through every one of our tests, but the interfaces look like 2016 and the AI assistance is the weakest in this cohort at 2.8. There is no free tier, which is unusual here. Good fit for a charity or association replacing a spreadsheet. Poor fit for anything a customer sees.

The dissenting view

One panellist rated the design axis higher, arguing the theming options are better than the defaults suggest. The score reflects what a buyer gets without design work.

One member of the panel disagreed with the consensus. We publish the disagreement rather than average it away.

What works / What does not

  • No free tier and no code export

  1. Editor panel

    I could not make it look acceptable

    Hannah Lindqvist@hannahlindqvist

    Product designer. I judge a builder by what it does to my spacing.

    Brought in to improve a client's member portal built on Knack. I spent two days in the theming options and could not get it past looking like a form from 2015. The underlying data structure was sound, so we kept it and put a different front end on top, which was more work than it should have been.

    Pros
    Solid data model underneath.
    Cons
    Theming cannot rescue the visual output.

  2. Editor panel

    Unglamorous and it has never once fallen over

    Laila Benali@lailabenali

    Programme coordinator at a non-profit. Every tool I choose has to survive a grant audit.

    Our volunteer register, applications and case notes have lived here for three years. It looks dated, my colleagues mention it monthly, and it has not lost a record or gone down. For an organisation where continuity matters more than appearance that trade is worth making. Wish there were a free tier for testing ideas.

    Pros
    Very stable. Roles and forms work properly out of the box.
    Cons
    Interface looks a decade old and no free tier to trial.

Frequently asked

Does Knack have a free plan?
No, only a trial. Paid plans start at about 39 EUR per month, which is worth knowing before you invest time in a build.
Is Knack good for customer-facing apps?
Only if appearance does not matter. Design scores 2.9 and SEO 2.6. It is built for logged-in operational use.
Knack or Airtable?
Knack if you need roles, forms and permissions out of the box. Airtable if you need collaborative data plus a bigger integration ecosystem.
