Smart Open
Paste anything -> we detect the tool.
Smart input for timestamps, UUIDs, cron expressions, JWTs, Base64, and JSON, with a polished handoff into the right tool.
Developer utilities that feel fast, sharp, and worth bookmarking.
Test regex, convert timestamps, decode JWTs, inspect Base64, parse cron schedules, generate UUIDs, format JSON, convert YAML, and debug payloads in a workflow that feels cleaner than the usual utility-site mess.
Top Tools
High-intent tools first, category depth behind them.
The homepage stays selective. Featured tools capture the biggest workflows first, while category hubs keep the long-tail surface area organized for search and humans.
SEO structure
Featured tools, related links, and clean category hubs instead of one giant link dump.

Why timedev
Utility workflows with a higher product bar.
The tools matter, but the experience around them matters too. The goal is fewer clicks, better hints, and a visual layer that feels deliberate enough to trust.
Fast by default
Every tool runs entirely in your browser. No round trips, no loading spinners. Results appear as you type.
Paste-first debugging
Smart Open routes timestamps, UUIDs, cron expressions, JWTs, Base64, and JSON into the right workflow before you start clicking around.
Helpful without getting in the way
Rule-based hints and AI explanations stay close to the output, so you get context when you need it without turning the site into a chat app.
The Platform
A real category system, not a random utility pile.
timedev.ai is now organized as a tool platform with category hubs, related-tool graphs, and focused entry points for the workflows developers repeat every day.
Every category is connected to the same registry, so homepage sections, tool pages, hubs, and sitemap entries stay in sync as the product grows.

For AI + Search
Built to be readable by both humans and machines.

Smart Open
Paste anything. We figure it out. Strong-format detection sends developers to the right tool instead of making them browse the tool list manually.
