Migrateplan
The migration that can be undone
Problem
A migration drops a column on Friday. The rollback exists in theory and has never been run. When it is needed at 6pm, it fails, and the recovery is a backup restore that loses the afternoon's writes.
Why now
Agents now write migrations, which means more of them, written faster, reviewed less carefully. The volume went up and the scrutiny went down.
Solution
It runs your migration and its rollback against a copy of production before it ever touches production, and tells you what the rollback would actually lose. A migration that cannot be safely reversed is flagged before Friday, not during it.
Who it is for
A small team without a DBA, shipping schema changes into a database that matters. The rollback exists in theory and has never been run, so when it is needed at six on a Friday it fails, and the recovery becomes a backup restore that loses the afternoon's writes. Agents now write migrations too, so there are more of them, reviewed less.
What you could earn from Migrateplan
Say you build Migrateplan and charge your own customers $25 a month, the price the score suggests. The numbers below are the revenue that would come from them. This is money you earn, never a fee you pay UpgradIQ, and we never take a cut. It is arithmetic off the price, not a promise the customers arrive on their own.

Your build kit for Migrateplan
Start the build and the kit opens two steps in, then drip-feeds the rest one phase at a time. Every phase is a copy-paste prompt for your agent with its own verification before the next unlocks, so Migrateplan moves from an empty folder to a running MVP without you ever holding the whole plan in your head.
Progress saves across every device, and the workspace always reopens on the exact step you left, so a build that runs over several weeks survives them instead of dying in a browser tab you eventually close.
How you actually build it
Connect your coding agent once. It pulls the current phase straight from your kit over MCP: the exact prompt, the outcome to aim for, and the check to run before it moves on. You review and ship, it does the typing.
No copy-paste juggling, no thread to lose. The kit stays the single source of truth, and your agent works through it one phase at a time, verifying its own work at each step before the next phase is unlocked.
Take the context file, free
This is the AGENTS.md that keeps your coding agent on scope for the entire build: what Migrateplan is, who it is for, the stack, the non-goals, and the rules it must follow. Copy it into your project now, no account needed, and your agent is briefed before you write a line.
# Migrateplan The migration that can be undone ## What this is It runs your migration and its rollback against a copy of production before it ever touches production, and tells you what the rollback would actually lose.

Agents now write migrations too, so there are more of them, reviewed less. ## Stack Next.js + Postgres ## Non-goals Do not build features outside the core job above. This product exists to do one thing well. Every extra feature is a reason it does not ship. ## Rules for the agent - Build one phase at a time. Do not run ahead into later phases. - Validate input at every boundary where data enters. - Never put a permission or plan check in client code. - Ask before adding a dependency that a few lines would cover. - If something is ambiguous, say so rather than inventing a requirement. --- Context file from UpgradIQ · idea migrateplan · prompts kit-v4

The path to a running MVP
Foundation
Scaffold the stack, then wire the data model and sign-in. It is the skeleton Migrateplan stands on, and it goes up in an evening rather than a lost week of config.
The product
Build the core feature end to end, then wire how it charges. This is where Migrateplan finally turns into something that a stranger will actually pay you for.
Ship it
Test and harden, deploy it live, then open the launch-day toolkit that lands the first ten users who prove it.
Is Migrateplan for you?
- You want revenue reasonably soon, not a science project
- You can give it evenings and a couple of weekends
- You can reach Small teams shipping schema changes
- You are not ready to talk to a first real customer
- You want it fully passive, with zero maintenance
- You expect it to find its own customers without you

Frequently asked
Is Migrateplan actually validated?
It scored UIQ 77 with a GO verdict, weighed across eight sub-scores on the same rubric as every idea. GO means 75 and above, so demand and buildability were judged, not guessed.
What stack does it use?
Migrateplan is built on Next.js + Postgres, chosen because a coding agent can carry most of it. You are not fighting infrastructure, you are shipping the feature that matters.
How long to a running MVP?
The kit is ten phases, drip-fed one at a time so you always know the single next step. An evening and a weekend for the lighter builds, a few focused weeks for the deeper ones.
What does the $25 a month mean?
It is the price the model suggests Migrateplan could charge its own customers, not a fee to us. It is here so the money question is answered before you build, not after.
Which agent do I need?
Any capable coding agent: Claude Code, Cursor, Lovable, or Bolt. Every phase is a copy-paste prompt with its own check, so the agent does the typing and you keep the judgement.
What is free versus Pro?
The whole case above is free: the problem, timing, solution, buyer, and the full score. Pro adds how it makes money, the one risk that could kill it, and the full kit that carries Migrateplan from an empty folder to a running MVP.
