Instagram tools that never ask for your loginStealthGram is also written Stealth Gram and searched as stealth gram.

If you are not sure where to begin: read the analytics guide if a number in your Insights confused you, the pricing guide if a brand has asked for your rate, the sizes reference if something got cropped, the captions guide if your text is not behaving, and the safety guide if you are worried about an account or were caught by something that asked for your password.

Why a browser-only toolkit is the point, not a limitation

Most free Instagram tools work the same way: you paste something in, it goes to their server, the server does the work and sends an answer back. That is a perfectly ordinary way to build software, and for most things it is fine. It stops being fine the moment the thing you are pasting in is personal — your unpublished caption, your client’s campaign image, your follower numbers before you have told anyone.

StealthGram is built the other way round. There is no application server behind these tools. When you load a tool page, your browser downloads a JavaScript file and then runs it locally, in the same sandbox that runs every other page you have open. The engagement rate calculator does arithmetic on numbers that never leave the input box. The carousel splitter uses the Canvas API to slice an image that only ever exists as an object URL in your own memory. The grid planner saves your arrangement in localStorage — a store that belongs to your browser, on your machine, that no server here can read.

What that costs you, honestly

A client-side architecture is not free of trade-offs, and it would be dishonest to pretend otherwise:

• Your work does not follow you between devices. A grid plan saved on your laptop is not on your phone, because the only copy is in your laptop’s browser storage. Clearing site data deletes it.
• Nothing here can read your actual account. Tools that connect to Instagram can pull your real numbers; you have to type yours in. That is the direct consequence of never asking for your login.
• Very large images are limited by your device. Canvas work happens in your own memory, so a 100-megapixel file behaves differently on a five-year-old phone than on a desktop.
• JavaScript is required. There is no server-side fallback, because a server-side fallback would mean sending your data to a server.

We think those are the right trade-offs for this kind of tool. You may not, and that is a reasonable position — it just means a different tool suits you better.

What we deliberately do not build

There are popular Instagram “tools” we will not make, because they cannot be made honestly:

• Private account viewers. Every single one is a scam or a phishing page. If an account is private, the images are not served to you, and no website can change that. Tools claiming otherwise exist to harvest logins or to make you complete endless “human verification” offers. We wrote up exactly how that scam works, including what to do if you already entered a password into one.
• Follower buying and engagement pods. Bought followers wreck the one metric brands actually check — your engagement rate — and violate Instagram’s terms. We would rather show you the arithmetic of the damage than sell it to you.
• Anything that needs your password. “Who unfollowed me” trackers, auto-DM bots and scheduling tools that ask you to log in through their own form are handing your credentials to a third party. Instagram’s own Insights already tell you most of what those tools promise.
• Downloaders for other people’s content. Saving someone else’s photos to reuse is a copyright problem, not a technical one.

Where our numbers come from

Several tools compare your figures against benchmarks — engagement rate by follower tier, sponsored post rates by niche, active hours by audience type. Those benchmarks are published ranges from creator-marketing reporting and platform documentation, not a private dataset and not live Instagram data. We show you the exact multiplier applied at every step so you can disagree with a number and adjust it, rather than trusting a black box. Where a tool cannot know something, it says so instead of inventing a figure.

That principle occasionally works against us. The rate calculator tells you, in its own results panel, that its engagement multiplier bottoms out at ×0.70 — which means it will still quote a higher price for an account padded with bought followers than for a smaller genuine one. A brand running a real audit will not. We would rather publish that limitation than let the number look more authoritative than it is.
