Are DharmOps' free database tools really free?

Yes. All 8 tools — including the SQL Query Analyzer, Database Cost Calculator, Data Infrastructure Health Score, and pgvector vs Vector DB Advisor — are free to use with no signup, no credit card, and no usage limits. They give you instant results based on what you enter.

What database problems can these tools help me diagnose?

They cover the most common sources of database pain: slow SQL queries and missing indexes, confusing EXPLAIN ANALYZE output, the monthly cost of a slow database, cloud database overspend, N+1 query problems, overall infrastructure health across 6 areas, pgvector vs. managed vector database decisions, and whether adding Redis caching would pay off.

Do I need to sign up or share my database credentials to use these tools?

No. Every tool runs on the numbers, queries, or answers you type in directly — there's no signup, no database connection, and nothing to install. You get your result immediately in the browser.
