DB Fiddle is useful for testing SQL snippets online. But it runs queries on a shared server, supports limited databases, and you can’t bring your own data. PondPilot is a different kind of SQL playground.
PondPilot vs DB Fiddle
| DB Fiddle | PondPilot | |
|---|---|---|
| Execution | Shared server | Your browser (WASM) |
| Data | Manual CREATE/INSERT | Drop your own files |
| Engine | MySQL, PostgreSQL, SQLite | DuckDB |
| Privacy | Queries go to server | Everything stays local |
| Rate limits | Yes | No |
| File support | None | CSV, Parquet, JSON, DuckDB |
Bring Your Own Data
DB Fiddle requires you to manually define schemas and insert data with SQL. PondPilot lets you drop a CSV, Parquet, or JSON file and query it immediately. Much faster when you want to test queries against real data.
DuckDB’s Modern SQL
DB Fiddle supports MySQL, PostgreSQL, and SQLite. PondPilot gives you DuckDB — a modern analytical SQL engine with features the others lack:
GROUP BY ALL(no repeating column lists)PIVOT/UNPIVOT- List and struct types
- Advanced window functions
- Native Parquet and JSON support
No Rate Limits
DB Fiddle throttles queries because they cost server resources. PondPilot queries run on your hardware — no limits, no throttling, no “too many requests” errors.
Embeddable
Need a SQL fiddle in your documentation? PondPilot Widget embeds an interactive SQL editor in any webpage. Like DB Fiddle, but embeddable and server-free.
Privacy
DB Fiddle stores your queries on their servers and assigns them public URLs. PondPilot stores nothing — queries exist only in your browser tab.
When DB Fiddle is the better choice
DB Fiddle is the right tool when you need to reproduce something on a specific MySQL, PostgreSQL, or SQLite version and share a public link in a bug report or forum thread. That’s what it’s built for, and the shareable URL is the point. PondPilot runs DuckDB, not those engines, and keeps everything in your browser, so there’s no public link to hand out. If you need engine-specific behavior or a shareable permalink, use DB Fiddle. If you want to query your own files with modern analytical SQL and keep the data private, PondPilot is the better fit.
FAQ
Is PondPilot a drop-in replacement for DB Fiddle? Not quite — they solve different problems. DB Fiddle reproduces SQL on MySQL, PostgreSQL, or SQLite and gives you a shareable public link. PondPilot runs DuckDB in your browser against your own files, with nothing sent to a server.
Can I query my own files? Yes. Drop a CSV, Parquet, JSON, or DuckDB file and query it right away — no CREATE TABLE or INSERT. DB Fiddle has no file support; you define the schema and insert rows by hand.
Does my data get uploaded anywhere? No. PondPilot runs DuckDB compiled to WebAssembly in your browser, so queries run locally and your data never leaves the tab. DB Fiddle runs your queries on a shared server.
Is it free? Yes — PondPilot is free and open source, with no rate limits and no signup.
