Beautify or minify SQL with full control over dialect (PostgreSQL, MySQL, SQLite, SQL Server/T-SQL, BigQuery, Snowflake, and more), keyword / identifier / function casing, indent style (standard, tabular-left, tabular-right), and spacing between statements. Produces a syntax-highlighted, copy-ready result with live size and statement stats.

Plan and visualise an API latency budget. Enter a P99 target (e.g. ≤ 300ms) and per-stage allocations (DNS, TCP, TLS, TTFB, Processing, Network) to see a live waterfall, budget utilisation, and over-budget warnings. Optionally paste an OpenTelemetry or Datadog trace to reverse-engineer a measured allocation.

An interactive JSONPath REPL that runs multi-step query pipelines against any JSON. Write one JSONPath expression per line (e.g. $..book[?(@.price<10)] then $[0:5]) and see each step's matches with counts, paths, and values — plus a shareable URL that encodes your data and pipeline. Supports recursive descent ($..), wildcards ([*]), filters ([?(@.price<10)]), slices ([0:5:2]), and negative indices.

Parse a 5-part / 6-part / Quartz cron expression into a plain-language schedule description, show the field-by-field breakdown, and list the next N execution times in any IANA timezone — with an AI-generated natural-language explanation in your language
