Everything your app needs to go live.
TanStart is a launch asset workspace for developers. Generate favicons, OG images, privacy policies, and more — all from one place. Pay per project, not per month.
Built by indie hackers, for indie hackers.
Brand Kit
OG Image
Legal Docs
You've built the app. Now comes the annoying part.
Every new project means the same ritual: visit favicon.io to generate icons, hop to another tool for OG images, spend 30 minutes on Termly answering generic legal questions, manually write a robots.txt, google “twitter card image size” for the 50th time, and pray you didn't forget anything before hitting deploy.
It's 4-8 hours of busywork that adds zero product value. And you do it every. single. time.
Three steps. One launch kit.
Create a project
Drop your logo (or generate one), name your app, select your platform — web, mobile, or both.
Generate your assets
Pick what you need: brand kit, OG images, legal docs, device mockups. Each generator is purpose-built for developers.
Download and ship
Get everything as a zip, copy code snippets, or grab hosted URLs for legal pages. You're launch-ready.
Everything between “it works”and “it's live”

Stack-Aware Legal Docs
Most privacy policy generators ask 30 generic questions. TanStart works differently — select the services you actually use and get legal documents that specifically describe how each service handles data.
- Privacy Policy, Terms of Service, Cookie Policy
- Tailored to your actual tech stack
- Export as Markdown, HTML, React, or hosted page
- One-time cost — no monthly subscription
