Is a Knack Alternative Worth Building Instead of Renting?

Your records come out cleanly. Knack exports every object as CSV, TXT, or JSON, so the tables themselves move without drama. Two things do not come out. File attachments export as links back to Knack, not as files, so someone has to download them before the account closes. Your roles and permissions do not transfer at all, because they are Knack's own architecture. We rebuild those from your current setup and check them against real logins before cutover.

You do, in writing. This matters more than most buyers expect. Under US copyright law the person who writes the code owns it by default, even when you paid for it. The work made for hire exception mostly covers employees, not outside firms, and commissioned software often falls outside the nine categories the statute lists. Ownership moves only through an express written assignment. Ours says so plainly, and you get the repository in your own account from the first commit.

Most apps ship in stages over four to ten weeks. Stages matter more than the total. We start with the screens your team opens every day, so you get something usable early instead of waiting for one big launch. What moves the number is the count of objects, how many user roles need different views, and whether anything connects to an outside system. Heavy reporting adds time. A straight rebuild of a form and a list does not.

Not always, and we will say so. As of August 2026, Knack's published pricing runs $59 a month at 20,000 records, $130 at 50,000, and $300 at 125,000. Under a few hundred a month, renting usually wins on pure cost. The math changes when your bill hits four figures, when a record cap forces an upgrade you did not plan, or when the app runs work you cannot afford to lose. Run your own numbers against custom software vs SaaS first.

You keep everything built so far, and it runs without us. There is a test for this that costs you nothing. Hand the repository and the setup documentation to any developer who did not build it, and ask them to run the app locally. If they can do it without calling us, the handover is real. If they cannot, it was never a handover. We would rather you run that test than trust the promise.

Then do not rebuild the app. Sometimes the platform is fine and one workflow inside it is miserable, usually something involving retyping between tabs. A Chrome extension can fix that part and leave the rest alone, for a fraction of a rebuild. We also replace Caspio and Airtable when the whole platform is the problem.
