Built by a marketer, for marketers

The problem we solve

Growth marketers spend a disproportionate amount of time on operational work: building UTMs, generating QR codes, reformatting data, verifying screenshots, checking ad safe zones. Most tools that help with this are locked behind expensive SaaS plans, require account creation just to run a query, or are so bloated they're slower than doing it manually.

MarketerTools is the opposite. Every utility is available immediately, runs in your browser with no upload to a server, and does exactly what it says. Nothing more.

What we're building

We're building the most comprehensive free toolkit for growth marketers: an all-in-one suite covering the operational and manual tasks that eat into your day. Campaign URL building, QR code generation, keyword match type conversion, screenshot validation, Meta safe zones, spreadsheet operations, JSON formatting, and more.

Logged-in users get extras: saved presets, URL shortening with link analytics, and cross-session history. But signing in is optional. The tools work either way.

Who we are

MarketerTools is an independent project run by Aswin Sampathkumar, a growth marketer with experience across paid growth, ASO, and growth strategy for apps and SaaS products. It started as a side project and became a real product — used daily by growth marketers at agencies, startups, and growth teams.
