Software development involves small, recurring, mildly annoying chores: turning a cramped SQL query into something readable, exploring a complex JSON payload as a tree, checking what's actually inside a JWT token. For these, developers usually paste data into whatever unfamiliar online tool shows up first in search results — an uncomfortable habit from both a trust and a privacy standpoint.
So we put 24 small tools together in one place at axios.com.tr/gelistirici-araclari: SQL, JSON and HTML formatters; a JSON Tree viewer; a JWT decoder; hash and UUID generators; a password generator with rich parameters; a regex tester; a color converter; a CSV⇄JSON converter; a Markdown previewer; a cron expression parser; and a QR code generator supporting vCard, email, phone, SMS and WiFi payloads, downloadable as PNG/SVG/PDF.
Everything runs entirely in your browser — whatever you paste in never reaches a server. That removes the "where does my pasted code actually go" question up front; you can paste a production connection string or a JSON containing customer data without hesitation.
To prevent abuse, each tool has a daily per-IP usage cap, and a verification layer filters bot traffic in the background — tuned so it never gets in the way of a developer's normal daily use.
Why offer these for free? Because they're the same small utilities our own team already uses on projects every day. Publishing them cost us nothing extra, and it turned axios.com.tr into a resource that's genuinely useful to developers.
Give them a try, and if you think of one we're missing, let us know — we'll keep adding tools over time.
