# StealthGram > Free Instagram utilities that run entirely in the visitor's web browser. No sign-in, no Instagram credentials, no file uploads, no server-side processing of user input. Independent project; not affiliated with Instagram or Meta Platforms, Inc. Site: https://stealthgram.in.net/ ## What this site is StealthGram publishes 12 client-side tools plus plain-English guides. Every tool is a JavaScript module the browser downloads and executes locally. There is no application backend: no data the visitor types, pastes or opens is transmitted anywhere. Images opened in the image tools are read with the Canvas API from a local object URL and are never uploaded. ## What this site deliberately does not offer - No private-account viewers (they are universally scams or phishing) - No follower/like purchasing, engagement pods, or automation bots - No tools that ask for an Instagram username or password - No downloaders for other people's content ## Tools - [Engagement Rate Calculator](https://stealthgram.in.net/tools/engagement-rate-calculator/): Work out your real engagement rate by followers or by reach, and see how it sits against the benchmark for your follower tier. - [Influencer Rate Calculator](https://stealthgram.in.net/tools/influencer-rate-calculator/): Turn followers, engagement and usage rights into a defensible price range you can take into a brand negotiation. - [Follower Growth Calculator](https://stealthgram.in.net/tools/follower-growth-calculator/): Project how long your current growth rate takes to reach a target, under both linear and compounding maths. - [Best Time to Post Calculator](https://stealthgram.in.net/tools/best-time-to-post/): Convert your audience’s active hours across up to three time zones into a heatmap in your own local time. - [Instagram Font Generator](https://stealthgram.in.net/tools/font-generator/): Eighteen Unicode text styles you can paste into a bio or caption, with an honest note about which ones break screen readers. - [Bio Line Break Generator](https://stealthgram.in.net/tools/bio-line-break-generator/): Instagram eats ordinary line breaks in the bio field.
