The Ultimate Developer's Sidekick, Feature by Feature.

Scratch Tabs is more than a scratchpad. It's a powerful suite of integrated tools designed to handle every intermediate data task in your workflow. Explore the features that make it indispensable.

Instant Intelligence for Over 40 Data Formats

Scratch Tabs is a polyglot data environment. When you paste data, it's not just formatted—it's loaded into a specialized, interactive "workbench" or "smart view" that understands its structure.

When analyzing a messy API response, just paste the minified JSON. Scratch Tabs instantly formats it and presents an interactive tree view, letting you collapse nodes and search for keys without manual cleanup.

JSON tree view
Log parsing

When troubleshooting production errors with scattered log entries, just paste the multiple log lines. Scratch Tabs instantly parses and filters them, making error patterns immediately visible. For JSON logs with metadata prefixes, it automatically cleans them leaving pure JSONs.

When struggling to understand a complicated regex pattern, paste it into the regex tablet. Scratch Tabs provides a human-readable interpretation of what the pattern actually matches.

Regex explanation
Cron breakdown

When unsure if cron expressions will parse equivalently across systems, paste the cron syntax. Scratch Tabs gives you a full breakdown of the schedule timing and execution pattern.

When dealing with a messy application.properties file from a legacy system, paste the content. Scratch Tabs intelligently cleans and groups properties with one-click functions for instant organization.
