Built By Marketers Who Ship Every Day.
Most free marketing tools online are lead magnets in disguise. Locked features, forced signup, an email sequence the next morning. We built these because our own team needed them, and we made them free because that is how the internet used to work.
Every tool is opinionated. It reflects how we run performance campaigns for real Indian and global brands, and how we audit tracking setups before a single rupee is spent on ads.
Model unit economics, break even and target CPA before you upload a campaign.
Prove ROI on contribution margin, not vanity metrics.
Validate GA4, Meta CAPI and Google Ads conversions in one scan.
Generate headlines, offers and CTAs in seconds, then edit like a human.
Everything You Wanted To Ask.
Are all the tools really free?
Yes. Every tool here is free forever. No signup, no credit card, no daily limit and no hidden paywall.
Do I need to create an account?
No account required. Open any tool and start using it. Your inputs stay in your browser.
Which tools should I start with?
Most paid media teams start with the ROAS, CPA and Break-even ROAS calculators, then use the Pixel Checker and Tracking Validator to make sure their conversions are firing.
Can I use these for client work?
Yes. Freelancers, in-house teams and agencies are welcome to use every tool for audits, reports and client deliverables.
Are these tools safe to use?
Yes. Calculators and generators run entirely in your browser. Nothing is stored or sent to a server unless the tool explicitly needs to fetch a public URL, like the Pixel Checker.
