Our free data engineering tools
Snowflake cost tools
Snowflake Cost Calculator - full monthly spend estimator. Model compute, storage, Snowpipe, Cortex AI, and serverless feature costs across all editions and regions.
Credit -> USD Converter - instant credit price lookup. Convert any credit count to USD across Standard, Enterprise, Business Critical, and VPS editions for every supported cloud region.
Query Cost Estimator - price per query from bytes scanned and warehouse size. Includes the 60-second resume minimum and scales to daily and monthly totals.
Warehouse Sizing Estimator - recommends a starting warehouse size (XS to 6XL) from workload type, data volume, and concurrency. Shows one-size-up and one-size-down cost comparison.
Databricks & dbt cost tools
Databricks Cost Calculator - DBU + underlying cloud VM pricing estimator. Pick SKU (Jobs, All-Purpose, SQL, Serverless), cluster size, and runtime hours across AWS, Azure, and GCP.
dbt Cloud Cost Calculator - price dbt Cloud plans by developer seats, successful model runs, and job concurrency. Compares Developer, Team, and Enterprise tiers.
SQL & data productivity tools
SQL Formatter - beautify messy SQL instantly. Handles Snowflake, BigQuery, PostgreSQL, and ANSI SQL with configurable indent size and keyword case.
Cron Expression Builder - build and validate cron expressions visually. Preview the next 5 fire times and copy schedules for Airflow, dbt Cloud, Snowflake Tasks, or Databricks Jobs.
JSON to SQL DDL - paste a JSON sample, get a CREATE TABLE statement. Supports Snowflake VARIANT, PostgreSQL JSONB, BigQuery STRUCT, and standard SQL types.
CSV to SQL Converter - paste CSV data, get CREATE TABLE DDL and INSERT statements with inferred types. RFC 4180 compliant parser, Snowflake/Postgres/BigQuery/ANSI dialects.
dbt Schema.yml Generator - paste a CREATE TABLE, get a dbt schema.yml with inferred unique/not_null tests, a staging SQL model, and a sources.yml entry with freshness checks.
Unix Timestamp Converter - epoch to human date and back. Auto-detects seconds, milliseconds, microseconds, nanoseconds. SQL cheat sheet for Snowflake, Postgres, BigQuery, MySQL, Redshift, Databricks.
Multi-cloud cost calculators
BigQuery Cost Calculator - model on-demand ($6.25/TB scanned) and capacity Editions (Standard/Enterprise/Enterprise Plus slot-hours), storage tiers, and streaming ingest. Includes on-demand vs Editions break-even analysis.
SQL practice
SQL Playground - in-browser SQL engine powered by DuckDB-WASM. Practice window functions, CTEs, QUALIFY, aggregations, and joins on preloaded sample datasets. No server, no signup, 100% client-side.
Data format conversion
JSON / Parquet / Avro Converter - convert between JSON, Apache Parquet, and Apache Avro directly in your browser. Powered by DuckDB-WASM for Parquet and avsc for Avro. No upload, no server — 100% client-side.
Optimizing a slow Snowflake query? Use the Query Cost Estimator to compare cost before and after applying clustering keys, Search Optimization Service, or materialized views.
Reviewing a Snowflake invoice? Plug credit counts from ACCOUNT_USAGE into the Credit Converter for quick dollar-value checks.
Comparing Databricks vs Snowflake? Run the Databricks Cost Calculator for the same workload hours and compare DBU + VM cost against a Snowflake estimate.
Budgeting dbt Cloud seats? The dbt Cloud Cost Calculator prices developer seats, model runs, and concurrency across Developer, Team, and Enterprise tiers.
Shipping SQL to production? Clean it first with the SQL Formatter - consistent formatting makes code review faster and cuts merge conflicts.
Scheduling a pipeline? Build the schedule visually in the Cron Expression Builder and paste the expression into Airflow, dbt Cloud, Snowflake Tasks, or Databricks Jobs.
Modeling a new JSON source? Drop a sample into the JSON to SQL DDL generator to scaffold your CREATE TABLE statement in seconds.
Loading a CSV export? Paste into the CSV to SQL Converter for instant CREATE TABLE + INSERT scaffolding - great for seeds, fixtures, and small lookups.
Onboarding a new table into dbt? Run the dbt Schema.yml Generator on the CREATE TABLE to auto-scaffold schema.yml, staging SQL, and sources.yml with freshness checks.
Debugging timestamp data? The Unix Timestamp Converter handles seconds, milliseconds, microseconds, and nanoseconds with SQL examples for every major warehouse.
Running on Google Cloud? Use the BigQuery Cost Calculator to model on-demand vs capacity Editions pricing and find the break-even point for your workload.
Practicing SQL? Open the SQL Playground — run queries on preloaded sample tables directly in your browser with DuckDB-WASM. No setup required.
Converting file formats? The JSON / Parquet / Avro Converter handles all six conversion paths between JSON, Parquet, and Avro — powered by DuckDB-WASM and avsc, entirely in your browser.
Are these tools free?
Yes. Every tool on this page is free, requires no login, and stores nothing on our servers. All calculations and transformations run in your browser. Share the configured URL with your team - the query string preserves all inputs.
How accurate are the cost estimates?
Estimates use each vendor's publicly documented list pricing as of 2026 (Snowflake editions, Databricks DBU rates, dbt Cloud plan tiers). Actual invoiced cost depends on your contract (capacity deals typically discount 20-40% off list), regional pricing, and real usage patterns. Always verify against your vendor's usage views (Snowflake ACCOUNT_USAGE, Databricks System Tables, dbt Cloud admin console) for authoritative billing data.
