Changelog
Below is a reverse-chronological record of Oltool feature launches and content updates. We stay privacy-first and keep maintaining — so every tool earns your trust.
Shipped user-state and trust signals: local favorites & recent tools, per-tool input history (auto-skipped for sensitive tools), a site-wide Changelog, per-tool "last verified" dates, and an anonymous usage counter (count only, no identifiers or content collected).
Added content-updated timestamps across tool and blog pages; published 10 original developer tutorials (JSON, regex, character encoding, time zones, ports, color conversion, text diff, JSON Schema, JSONPath, ULID, etc.).
Bulk-enhanced tool page depth: added step-by-step guides, more use cases, FAQs, and authoritative references across all tools to meet minimum content standards.
Added topic hub pages and more reference sheets, improving the site-wide internal linking structure.
Added "related tools / related references / related topics" internal-link blocks on tool pages to strengthen the internal link graph and content discovery.
Improved the site-wide sitemap and hreflang multilingual mapping, optimizing indexing and canonical signals for search engines.
Published privacy policy, terms of service, and contact pages; added page-load performance optimizations.
Added structured data (SoftwareApplication / BreadcrumbList / FAQPage) to tool pages to improve search rich-result appearance.
Shipped dark mode, following system preference with manual toggle and consistent contrast across the site.
Added bilingual (Chinese/English) UI; tool names, descriptions, and page copy switch by language with synced canonical and hreflang.
Oltool launched with the first batch of 159 developer tools fully operational.
Completed the core tool set and the browser-local execution architecture (no data uploaded to servers), establishing the privacy-first positioning.
