BSTB's free social media tools cover the jobs creators repeat every week: generating and cleaning hashtags, counting characters, checking engagement rates, pricing brand deals, estimating YouTube and TikTok earnings and running ad and business numbers. Every tool is free, needs no account and works with figures you already have.

🔍 Empty toolbox for that combo. No tool matches those filters yet. Clear a filter, or request the tool you need.
Most creator tasks map to one of four goals: growing an audience, pricing a brand deal, estimating what a platform pays, or running ad and business numbers. Start from the goal and the tools you need are grouped underneath.
Write better posts and hashtags, keep your tags clean and watch what is trending before you post.
Know your engagement rate and a fair sponsored-post rate before a brand asks.
See what views, subs and coins are worth before you plan around them.
Check the metrics every campaign and creator business runs on.
The tools are free because BSTB is built by creators who needed them, and password-free because asking for account access is the first red flag BSTB checks when it reviews growth services. The same rule applies to the site's own tools.
Open a tool and use it. There is no account, no trial clock and no paid tier hiding the full result.
Tools take figures you enter or text you paste. None of them ask for a password or access to your accounts.
Each tool started as a job the BSTB team did by hand, from pricing a brand deal to cleaning a hashtag list, then got built so every creator can use it.
Quick answers on what the tools do, what they cost and how accurate the estimates are.
BSTB offers two kinds of free tools: growth tools that help you write, clean and track content, and calculators that turn your numbers into engagement rates, earnings estimates and ad metrics.
Use the category and platform filters at the top to find the one you need.
Yes. Every tool on this page is free to use with no paywall, no trial and no account.
BSTB is funded by its reviews and partnerships, not by charging creators for calculators.
No. None of the tools ask for a login, a password or access to your account.
That is deliberate: tools that ask for your password are one of the red flags BSTB warns about in its growth service reviews.
The money calculators give estimates based on the rates and formulas you enter, so they are as accurate as your inputs and should be used as a starting range, not a quote.
Run a low and a high scenario before you pitch a number to a brand.
Use the Cost-Per-Retained-Follower Calculator, which shows what each follower really costs once you account for the ones that drop off within 30 days.
Bought followers that do not engage lower your engagement rate, which is the number brands look at first.
Yes. BSTB builds tools around what creators ask for, and new ones are added to this page as they are released.
Requests that help many creators get built first.
Tell us the number you need or the task you repeat, and which platform it is for. Tools that help many creators get built first and go on this page free.
