Is the cheapest option the right one?

Price is one group of 3 fields out of 26. Everything else, features, limits, portability, how well any of it works for agents, is on the full convex vs alternatives: reactive backend platforms compared comparison.

What exit cost actually measures

  • Every vendor says your data is yours; that is true and not the question
  • Data extraction is a weekend for nine of these eleven
  • Rewriting the two thousand call sites that read that data is not
  • The ladder is about code, not bytes
  • Rung 1: standard SQL over the wire, leaving is a connection string
  • Rung 2: standard engine behind a vendor SDK, schema and queries port but auth, storage and realtime call sites get rewritten
  • Rung 3: proprietary API over an open self-hostable engine, data leaves cleanly but every read and write is vendor-shaped
  • Rung 4: adds a proprietary function runtime, so queries, mutations, subscriptions and the render model all go
  • Rung 5: rung 4 with no self-host and no self-serve export, making even the data a project
  • Open source does not lower the score by itself
  • AppwriteAppwrite logo, PocketBasePocketBase logo and ConvexConvex logo are all open source and all sit at 3 or 4
  • The licence governs who may run the server, not who rewrites the client
  • Sync engines score unusually well for their age, sitting beside a PostgresPostgreSQL logo you already control

Where the pricing hides

  • Sticker prices cluster between $15 and $30 a month and tell you almost nothing
  • Three mechanics decide the real bill
  • Per-seat pricing: ConvexConvex logo and AppwriteAppwrite logo charge per member on top of usage
  • A five-person team starts at five times the headline before a function runs
  • SupabaseSupabase logo charges per organisation; FirebaseFirebase logo charges nothing up front
  • On small teams this is usually the largest line and does not shrink when you optimise
  • Bandwidth: ConvexConvex logo, SupabaseSupabase logo, FirebaseFirebase logo, AppwriteAppwrite logo and NhostNhost logo meter egress separately
  • Reactive backends push on every change, so a chatty subscription is a bandwidth line, not a CPU one
  • Easy to miss when modelling costs against requests per second
  • Check what live queries re-send when one row changes
  • Idle: FirebaseFirebase logo, ConvexConvex logo and Neon cost approximately nothing when unused
  • A SupabaseSupabase logo Pro project bills compute by the hour regardless of traffic
  • Anything self-hosted bills you for the machine
  • For side projects and staging this dominates everything else

Realistic migration paths

  • ConvexConvex logo to PostgresPostgreSQL logo is the hard one, plan it before you need it
  • npx convex export gives a zip of JSONL per table that loads into PostgresPostgreSQL logo cleanly enough
  • The work is in the application
  • Put a repository layer between your components and ConvexConvex logo early, so reactive queries become one seam not hundreds
  • Do it while the app is small; retrofitting later is most of the migration cost
  • FirebaseFirebase logo to anything starts with the export format, the one genuinely closed artefact here
  • The managed Firestore export writes a format only Firestore imports
  • In practice you paginate collections through the Admin SDK and write your own JSON
  • Fine at gigabytes, painful at terabytes
  • Budget separately for translating security rules into row-level security or middleware
  • SupabaseSupabase logo to plain PostgresPostgreSQL logo is the easy case and the reference point
  • pg_dump, restore anywhere, replace supabase-js with your query builder, replace GoTrue with an auth provider
  • Weeks, not quarters, and that gap is the entire content of the exit-cost column
  • Adding a sync engine later is the underrated option
  • Electric and Zero sit beside PostgresPostgreSQL logo rather than replacing it
  • "Start on Neon and Drizzle, add Zero when the UI needs to feel instant" is a real sequence, not a rewrite
  • None of the all-in-one platforms support that shape

How is this pricing data collected?

  • Every cell written from vendor docs, pricing pages and hands-on SDK knowledge, then tagged with provenance
  • vendor-claimed cells come off a specific docs or pricing URL, dated to when last plausibly true
  • inferred cells are judgement calls or values reasoned from adjacent facts
  • Where a fact is genuinely unpublished, the cell is null and renders as an em dash rather than a guess
  • Prices are the lowest paid tier, monthly, in USD, excluding usage
  • Exit cost is the field this page exists for
  • A 1-5 judgement score, lower is better
  • Measures one thing: how much application code you rewrite to leave, assuming data is already extracted
  • Deliberately ignores how good, how cheap, or how likely to survive the platform is
  • A high score is not a verdict against a tool, it is the size of the bet you are placing
  • The five rungs are defined in the column tooltip; each score's reasoning sits in that tool's cell note

Pricing questions

Is Convex a good idea if I might need to leave later?

  • Only if you price the exit now
  • No SQL surface, so every query, mutation and subscription is rewritten on the way out
  • The reactive render model has no drop-in equivalent
  • Scores 4 of 5 on our exit-cost ladder
  • If the codebase may outlive the decision and you are unsure, start on PostgresPostgreSQL logo

Does self-hosting Convex remove the lock-in?

  • No, it removes vendor risk, a different problem
  • convex-backend is open under FSL-1.1-Apache-2.0 with documented self-hosting, so ConvexConvex logo disappearing cannot strand you
  • But self-hosted ConvexConvex logo still speaks the ConvexConvex logo query API
  • The cost of moving to something that is not ConvexConvex logo is unchanged
  • Exit cost and vendor risk are separate columns for a reason

How should a small team weight exit cost against speed?

  • By expected lifespan
  • Under twelve months and pre-product-market-fit, exit cost is nearly free and speed is everything: take ConvexConvex logo or Instant
  • Past that, rewriting a data layer costs engineer-months and the PostgresPostgreSQL logo options claw it back
  • ConvexConvex logo charges its fee at the end, in one payment, and you cannot pay it early
