Replatforming From Glide or Adalo: What You Keep and What You Rebuild

Every founder who built on Glide or Adalo eventually runs the same calculation. The app works, users like it, the monthly bill has crept past the cost of a part-time engineer, and three roadmap items cannot be built inside the platform. The honest answer is almost always to replatform, and the honest admission most agencies avoid making is that a Glide or Adalo migration is not a migration in the Webflow-to-custom sense. The data comes with you. Very little else does. The entire UX is platform-native, which means the components, the navigation, the screen transitions, and most of the logic wiring were authored inside a visual builder whose output you cannot export. You are not porting an app. You are rebuilding one on top of the data you preserve, and the sooner a founder internalizes that sentence the better the decisions that follow from it.

This is the guide most search results refuse to write, because the incentive of every platform and every replatform vendor is to promise a smoother path than exists. What follows is the actual shape of the work. Which pieces survive, which get rebuilt, how to translate a Glide Table or Adalo collection into a real Postgres schema, how to map user IDs so existing accounts keep working, and why the right target for almost every non-tech founder is a progressive web app rather than a React Native binary. Two real migrations anchor the examples, one from Glide and one from Adalo.

Why Glide And Adalo Apps Are Unusually Hard To Migrate

A Shopify store migrating to a new platform carries most of its work with it. Product data, customer records, themes expressed in a templating language, scripts written as flat JavaScript. The output of the previous platform is mostly portable text. Glide and Adalo are different. Both are visual builders that render apps using their own proprietary runtime. When you open Glide and drag an inline list onto a screen, Glide is not generating HTML or React code that lives in a repository. It is storing a description of the screen in its own database and interpreting that description at runtime through the Glide client. The same is true for Adalo. There is no export button that produces usable source code because there is no source code in the form you would want it. The app exists as configuration inside the platform, and the platform is the only thing that can run it.

This has two consequences. The frontend has to be rebuilt. Every screen, every component, every transition must be re-expressed in whatever new framework you choose. The logic that lived in the builder also has to be rebuilt. Glide actions, Adalo custom actions, conditional visibility, computed columns, show-if rules, all of it is configuration in the source platform and code in the destination. Founders who expect a lift-and-shift are always disappointed. Founders who expect a rebuild against preserved data come out ahead, because once you accept the scope you make better choices about which features to keep, which to drop, and which the old platform had been forcing you to hack around.

What You Actually Keep: The Data Model

The good news is real and it is the part of the migration that nobody emphasizes enough. Your data survives, and if it is well-shaped it survives cleanly. Glide stores every app in Glide Tables, which is their internal database, or in a connected Google Sheet or Airtable base for older apps. Adalo stores collections in its own backend or in an external database if you configured one. In both cases there is a CSV export path. In Glide, Tables can be exported one at a time from the data editor. In Adalo, collections export to CSV from the database panel. Those CSVs are the ground truth you are carrying forward, and the shape of those CSVs determines how much schema translation work you have ahead of you.

The translation target for almost every replatform should be Postgres, and the easiest on-ramp to Postgres for a non-technical founder is Supabase. Supabase gives you a managed Postgres database, a generated REST and GraphQL API over the tables you create, authentication, file storage, and row-level security, all through a dashboard that resembles the spreadsheet view you already understand from Glide. The schema translation is mechanical. Each Glide Table becomes a Supabase table. Each column becomes a typed column, which is the step where you do real work because Glide is loose about types and Postgres is not. A column that held numbers and blanks in Glide has to become a nullable numeric type in Postgres. A column that held date strings in mixed formats has to be normalized to a timestamp. A column that held image URLs in Glide stays a text column in Postgres, or becomes a foreign key to a storage object if you move the images into Supabase Storage during the migration.

The hidden difficulty is relationships. Glide fakes relationships through relation columns and lookups that run client-side. Adalo uses proper relational links inside its collections but exposes them in a way that is easy to misread. When you translate to Postgres you make the relationships explicit with foreign keys, and the migration script has to map the Glide row IDs or Adalo record IDs into real primary keys on the new side. The pattern that works is to keep the original ID as a column on the new table, let Postgres assign a new serial or UUID primary key, and write the foreign keys using a join on the preserved original ID during the initial load. Once the data is in and verified, the original ID column can be kept for audit purposes or dropped.

User Identity Is The Trickiest Preservation Problem

A data model migration is straightforward compared to preserving user identity, and this is where most replatforms either fail or force a password reset on every existing user. Glide authenticates users by email, with either an emailed PIN or a Google sign-in. Glide does not store passwords because it does not need to. Adalo stores email and password for its signup flow and uses its own auth system. In both cases the thing you care about preserving is the identifier that user records in your data are keyed by, which is almost always the email address.

On the Supabase side, the auth system also keys users by email but assigns each authenticated user a UUID that other tables reference through foreign keys. The migration sequence that works is to import the data first with the email address preserved as a plain column, then seed Supabase Auth with the known email addresses ahead of first login, and finally backfill the Supabase user UUID into the relevant rows by joining on email the first time each user signs in. The first-login backfill is the quiet detail that makes the whole thing work. Until a user actually signs in on the new app, you do not have their UUID. You do have their email. So every row that references a user carries the email during the transition, and a small trigger or a scheduled job swaps the email reference for a UUID reference the moment the Supabase user is created.

For Glide apps with PIN auth the user experience on the new side is close to identical. Supabase has magic link and OTP flows that replicate the emailed-code login Glide users already know. For Adalo apps with password auth the story is softer. You cannot migrate Adalo password hashes into Supabase because you do not have access to the hashes and even if you did the hashing schemes differ. The honest path is to force a password reset on first login, framed in the launch email as a security upgrade, which is the framing every replatform uses and which users accept without complaint as long as the reset flow is one click. The migration from the user's perspective is one email, one reset, and an app that loads faster than the one they were using.

Why A Progressive Web App Is The Right Target For Most Founders

The biggest decision in a Glide or Adalo replatform is whether to rebuild as a native app through React Native or Expo, or as a progressive web app installable to the home screen. The default answer in founder forums is React Native, because native feels like a step up from Glide. The correct answer for most founders is PWA, because native is a step up you do not need and pay for with every sprint for the rest of the app's life.

A PWA built on Next.js or Remix with Supabase as the backend gives you a mobile experience that is indistinguishable from a Glide or Adalo app for the things those apps actually do. List views, detail views, forms, image uploads, offline-friendly reads through a service worker, push notifications on Android and increasingly on iOS, home screen installation that launches full screen with no browser chrome. You get iOS and Android with one codebase, no App Store review cycle, no TestFlight, no binary upload every time you ship a fix. You deploy with a git push. The ceiling is real. True native features like tight camera integration, background location, Apple Pay sheets, and certain health and fitness APIs still require a native shell. But the floor of a modern PWA in 2026 is so high that the vast majority of Glide and Adalo apps were never using the native ceiling in the first place. They were CRUD apps with a nice UI, and a PWA delivers exactly that with less maintenance.

Going native through Expo is the right call when the app genuinely needs features a PWA cannot deliver, when the brand position requires App Store presence as marketing rather than as distribution, or when the team has real React Native experience already. The mistake is choosing Expo because it feels more serious than a PWA and then spending six months on the build pipeline, the certificates, the app review, and the update cadence instead of on product. Founders replatforming from a no-code tool almost never have the bandwidth for that overhead, and choosing PWA buys back the time they need to finally ship the features the old platform blocked.

Migration Story One: A Glide Marketplace That Moved In Four Weeks

The Glide app was a two-sided marketplace for a niche professional community, built over a weekend eighteen months earlier and grown to about four thousand monthly active users. The ceiling that forced the move was a six-month-old roadmap item, a real-time message thread with read receipts. Glide's messaging patterns depend on polling and cannot express read receipts cleanly. The founder had also hit the tier pricing wall.

The replatform took four calendar weeks. Week one was data export and schema translation. Six Glide Tables, about eighty thousand rows, three relation columns that became foreign keys, and one computed column that moved into a Postgres view. A Python script ran against the exported CSVs and loaded Supabase with a dry-run mode for spot checks. Week two was the frontend rebuild in Next.js with Tailwind and shadcn components, focused on the four screens that represented ninety percent of user time. Week three was the real-time messaging feature, built on Supabase Realtime in a single file. Week four was user migration, the launch email, and a parallel-run period with a banner in the Glide app pointing users to the new URL. After two weeks the Glide app was switched to read-only and after four the account was cancelled.

Migration Story Two: An Adalo Field Service App With Forty Custom Actions

The Adalo app was heavier. A field service team of about twenty technicians used it to log jobs, upload photos, and sync notes back to an office dashboard. The founder had built up forty-odd custom actions over two years, most of them conditional flows that decided what to show or do based on job status, technician role, and location. The ceiling was a combination of upload reliability on rural jobsites and the inability to queue work offline for sync on reconnection.

The replatform here was eight weeks. Weeks one and two were the data export and schema translation out of Adalo's backend into Supabase, with particular care around image assets, which moved to Supabase Storage with the old Adalo CDN URLs preserved for a grace period. Weeks three through six were the PWA rebuild with aggressive offline support through IndexedDB and a custom sync queue, the feature the whole project existed to solve. Weeks seven and eight audited the forty custom actions, about thirty of which were replicated as clean server functions or client-side conditions and ten of which were retired because they existed to work around Adalo constraints that no longer applied. Password reset was handled with a launch email a week before cutover. Zero users were lost.

How To Decide If You Are Ready To Replatform

The readiness test is not technical. It is whether the current platform is blocking real revenue or real features, and whether the monthly bill has crossed the threshold where a four-to-eight-week replatform pays back inside a year. If both are true, the work is worth starting. If only one is true, the better move is usually to wait another quarter and keep shipping inside the current tool. The mistake founders make is replatforming because the tool feels embarrassing to admit to, rather than because it is costing them something concrete. Platforms are not vanity projects. An app on Glide that makes money is a better app than a React Native rewrite that ships late.

If the time has come and you want a partner who has done this specific migration before, WitsCode runs Glide and Adalo replatforms as a fixed-scope engagement with the data export, schema translation, auth mapping, and PWA rebuild handled as one project. The first call is a walkthrough of your current app to size the logic surface and confirm the PWA-versus-native call, and the output is a plan you can execute with us or take elsewhere. Either way you leave with the honest scope, which is the single hardest thing to get in this part of the market.
