If you’ve worked on a backend for more than a few months, you’ve probably experienced this:
The database schema exists
The ER diagram is outdated
Documentation is either missing or wrong
New devs keep asking, “What does this table do?”
I kept hitting this wall across multiple projects — solo work, startups, and client codebases.
So instead of fixing the docs again, I built a tool to generate understanding directly from the schema itself.
That tool is called Vizora.
The Problem With Database Documentation
Most database documentation fails for the same reasons:
Diagrams are drawn manually
Docs are written once and never updated
Schema changes aren’t tracked clearly
Understanding relationships takes too long
And tools that connect directly to live databases introduce:
Security concerns
Credential handling
Read-only role complexity
Internal approval delays
All that friction just to understand a schema.
Vizora’s Approach (No DB Connections)
Vizora takes a different route:
Paste your database schema → get diagrams, explanations, and docs instantly
No live database connection
No credentials
No infra access
Just schema → intelligence.
You can paste:
SQL DDL
Prisma schema
Schema-only dumps
And Vizora handles the rest.
What Vizora Generates
From a single schema paste, Vizora produces:
🔹 ER Diagrams
Automatically generated
Accurate relationships
Always in sync with the pasted schema
🔹 Schema Explorer
Browse tables, columns, keys, and relations
Clean, readable structure
Easy to navigate large schemas
🔹 AI Explanations (Plain English)
What each table represents
How tables relate
Why certain structures likely exist
Useful for onboarding and handoffs
🔹 Auto Documentation (Markdown)
Living docs generated from the schema
Ready for GitHub, Notion, or internal wikis
No manual rewriting
🔹 Version History & Change Tracking
Every schema paste becomes a version
See what changed between versions
Useful during refactors and reviews
🔹 Exports
PNG / SVG diagrams
Markdown documentation
Easy sharing in PRs or docs
Why Schema-Paste > Live DB Access
I intentionally avoided connecting to live databases because:
Security reviews slow adoption
Many teams can’t grant DB access
Offline / legacy schemas still matter
Understanding structure ≠ querying data
Schema-paste makes Vizora:
Safer
Faster to try
Easier to trust
Usable anywhere
For most teams, that tradeoff is worth it.
Who This Is For
Vizora is built for:
Backend engineers dealing with complex schemas
Solo developers who want clean docs without overhead
Startups onboarding new engineers
Agencies handling multiple client databases
If you’ve ever said:
“I know this schema works… but I don’t really understand it anymore”
You’re the target user.
Current Status: Private Beta
Vizora is currently in private beta, and I’m actively looking for early users and feedback.
👉 Private Beta Access:

I’m especially interested in:
Real-world schemas
Pain points during onboarding
Missing features you’d expect
Final Thought
Databases are the foundation of most applications, yet they’re often the least understood part of the system.
Vizora exists to make schemas readable, explainable, and shareable — without adding risk or complexity.
If that sounds useful, I’d love for you to try it and share honest feedback.
