INTRODUCING CAPYSQUASH: AUTOMATIC MIGRATION CLEANUP

TL;DR: We built a tool that automatically consolidates your Postgres migration files while guaranteeing schema safety through Docker-based validation.

THE PROBLEM WE'RE SOLVING

If you've ever worked on a fast-moving project using Supabase, Neon, or any Postgres-based platform, you know the pain:

287 migration files. All sitting in your repo.

Every schema change creates a new file:

20250101120000_add_users_table.sql
20250101120100_add_email_column.sql
20250101120200_add_email_index.sql
... (284 more files)

THE CONSEQUENCES

CI/CD pipelines slow to a crawl - running 287 migrations takes time
Merge conflicts everywhere - multiple devs touching migration folders
Repository bloat - git clone takes forever
Impossible to debug - which file changed the users table again?
Team frustration - "do we really need 50 files to add 5 columns?"

WHY EXISTING SOLUTIONS DON'T WORK

"Just Manually Consolidate Them"

Sure, but:

Takes hours of developer time
Error-prone and dangerous
How do you know you didn't break something?
Nobody wants to do this regularly

"Reset Migrations on Each Release"

Doesn't work when:

You have a production database
Multiple teams are deploying
You need migration history for debugging

"Just Live With It"

This is what most teams do. But:

Your CI/CD gets slower each week
Onboarding new devs becomes harder
The mess compounds over time

INTRODUCING CAPYSQUASH

A BETTER WAY

CAPYSQUASH automatically consolidates your migrations while guaranteeing zero schema drift through Docker-based validation.

BEFORE

migrations/
├── 001_users.sql
├── 002_add_email.sql
├── 003_add_name.sql
├── 004_add_index.sql
├── ... (283 more)

287 files, 15 MB

<div className="border-4 border-foreground p-6 bg-background">
  <h4 className="font-black uppercase mb-3">AFTER</h4>
  <div className="brutalist-code text-xs">

migrations/
├── 001_initial_schema.sql
├── 002_user_features.sql
├── ... (10 more)

  </div>
  <p className="font-bold text-sm mt-3">12 files, 600 KB</p>
</div>

☑ Same exact database schema. Just cleaner.

HOW IT WORKS

The magic is in the Docker-based validation:

ANALYZE

Scan your migrations and identify consolidation opportunities

VALIDATE ORIGINAL

Spin up a Postgres container, apply all original migrations, dump the schema

CONSOLIDATE

Create new, consolidated migration files based on smart rules

VALIDATE SQUASHED

Apply squashed migrations to a fresh container, dump the schema

COMPARE

Byte-for-byte comparison of schema dumps. If they match: ☑ If not: ☒ abort

The guarantee: If CAPYSQUASH completes successfully, your database schema is mathematically identical to what you had before.

"We ran pgsquash on Friday afternoon. By Monday morning, our CI/CD was 10x faster and merge conflicts dropped to zero. Game changer."

SAFETY FIRST

We know you're thinking: "This sounds dangerous."

We thought so too. That's why we built multiple safety levels:

CONSERVATIVE

For production. Only combines identical operations. Zero risk.

STANDARD

Default. Combines compatible operations. Docker validated.

AGGRESSIVE

Maximum cleanup. Removes redundancy. Still validated.

Every single squash is validated through Docker. No exceptions.
