migrate
bring your project to briven.
we move convex, supabase, firebase, mongodb, drizzle, prisma, raw postgres, hasura and nextauth projects to briven for you. free during the beta. your current platform keeps running the entire time — nothing is moved, deleted, or modified until you press cutover.
what we promise
your source stays untouched
we only read from your current platform. nothing is moved or deleted until you press the cutover button — which we won’t do until you say so.
parallel-run for as long as you need
reads land on briven, writes stay on your source, until the numbers match. cutover is a button. 7-day rollback if you change your mind.
we do the move, you review
an operator pulls your schema, ports your handlers, and copies your data. you review every step in the dashboard before anything goes live.
free during beta
we’re not charging for migration help in the launch window. after beta, concierge moves are paid; the dashboard wizard stays free.
where are you coming from?
pick your current platform for a detailed look at how the move works — what comes for free, what we automate, what stays manual. start the migration from there.
convex
your TS schema + handlers port to briven; useQuery stays the same.
read the convex guide →supabase
postgres → postgres via pg_dump. edge functions port directly.
read the supabase guide →firebase / firestore
document → relational with shape decisions you approve per collection.
read the firebase / firestore guide →mongodb
flatten vs jsonb per field, streaming COPY into postgres.
read the mongodb guide →drizzle
lightest path — both ends are postgres with a TS schema.
read the drizzle guide →prisma
schema.prisma → briven DSL. PrismaClient → ctx.db chains.
read the prisma guide →raw postgres
straightest path — pg_dump | pg_restore + briven for the function layer.
read the raw postgres guide →hasura
postgres half is free. permission rules become function guards.
read the hasura guide →nextauth / auth.js
schema maps 1:1 to Better Auth. preserve session IDs or fresh sign-in.
