Firebase to Supabase Migration in Ripon
Moving Ripon applications from Firebase to Supabase, where the access rules have to be rewritten as database policies. Firestore rules and PostgreSQL row-level security both decide who sees what and express it entirely differently — and a policy that is subtly too permissive exposes data without producing any error at all.
Why this comes up
The problem
Security rules were reimplemented as row-level policies and one of them returns rows it should not.
What you get
What we deliver
- Every security rule translated to a row-level policy and tested individually
- Policies verified negatively, by confirming forbidden reads actually fail
- Denormalised collections restructured into relational tables where appropriate
- Users migrated with their credentials rather than forcing everyone to reset
- Storage objects moved with their access rules reproduced
- Real-time subscriptions rebuilt, since the two models differ in behaviour

Firebase to Supabase Migration in Ripon — common questions
- Why is the security translation risky?
- Because a mistake is silent. An overly broad policy returns data rather than raising an error, so nothing in testing indicates a problem — which is why each policy needs a test that asserts a user cannot read what belongs to somebody else.
- Should the data structure change?
- Usually somewhat. Firestore rewards denormalisation because joins are unavailable, whereas PostgreSQL handles relationships natively — so duplicated data maintained by hand can often become a single normalised record, which removes a class of consistency bugs.
- Do users have to reset passwords?
- Not necessarily. Firebase password hashes can be imported with the right parameters, which avoids asking every customer to reset — establishing whether that path is available is worth doing early, because the alternative costs active users.
- How does real-time differ?
- Supabase publishes database changes rather than document snapshots, so the shape of what arrives is different. Application code listening for updates needs rewriting rather than reconfiguring, and behaviour under reconnection deserves testing specifically — a client that missed changes while offline has to reconcile its state on returning, and Firestore handled a good deal of that quietly on your behalf.
- Do you work with businesses across North Yorkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including Ripon and the surrounding North Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Ripon businesses do you usually work with?
- Small-operator booking, ordering and payment systems, priced for independents rather than chains. Beyond that we work across Tourism & Heritage, Agriculture, Retail, Hospitality and Construction.
- Do you cover the areas around Ripon?
- Yes — we work throughout Yorkshire & the Humber, including York, Leeds, Durham. Ripon is an urban area of roughly 17,000+, and we take on work across the wider North Yorkshire region rather than the city boundary alone.
