For indie hackers
Test your side project before you post it
Launch day gives you one wave of attention. If the sign-up breaks for strangers, the post title gets scrolled past, or the page does not say what the thing does, that wave is gone. Mimiq lets simulated people try your app, read your page and react to your post title before you hit publish.
How do I test my side project before launching it?
Check three things before you post. Can a stranger sign up? Let simulated people try it on the live app in real browsers, with inboxes of their own for confirmation links. Does the landing page say what it is? Show it to simulated visitors and read why they would leave. Does the post title land? Compare two versions on the same simulated readers. Fix what breaks, then post.
You only get one launch per post
Indie launches fail in small ways. The magic link lands in spam, the sign-up button does nothing on the first click, the first screen after login is empty, the post title is a pun nobody gets. You built it, so you cannot see any of this. The comments will tell you, but only after the wave has passed.
- Sign-up for strangers: simulated people try it in real browsers, with working inboxes.
- The landing page: what a cold visitor understands, and why they leave.
- The launch post: compare two titles on the same simulated readers.
- First test free, then a $9 Starter (120 credits that never expire) or monthly plans from $49.
How it works
- 01
Deploy it publicly
Simulated people need an address anyone can open, with no password page in front of it. A free hosting subdomain works.
- 02
Let them sign up
Paste the address with a task such as 'Sign up and start using it'. Pick 1, 3, 5, 10 or 20 people; each one tries it in their own real browser for up to 40 steps.
- 03
Check the page and the post
Run the landing page as a page test, and compare two launch post titles in the headline tester.
- 04
Fix and rerun
Fix the step where most people stopped, deploy, and run it again on the same people to see who gets further.
Can strangers sign up?
Each simulated person fills in your sign-up with made-up details and an email address of their own on a Mimiq domain, with a working inbox. So a magic link or a confirmation code reaches them, and you find out whether it arrives, whether they can tell what to do with it, and what they see after it.
Every click and form entry records whether it moved them on, changed nothing or failed. A button that does nothing on the first click, or an error that only says "something went wrong", shows up as the step where people stopped.
They cannot sign in with Google or GitHub, so if social sign-in is the only option, they stop there. Anyone stopped by one is marked as blocked by the site, and if it stops everyone, the flow fails and nothing is charged. A staging or preview address without bot protection works, as long as it is public.
Does the page say what it is?
Launch traffic is cold and impatient. A page test shows your landing page to 25 simulated visitors in about 90 seconds; each one decides whether to sign up, stay, skim or leave, and says why. If most of them cannot tell what the product does from the first screen, fix that before anything else.
Describe the audience you are launching to, such as "developers who self-host their side projects" or "freelance writers", rather than the whole internet.
Does the post title land?
A launch post title is a headline, and headlines are where Mimiq's evidence is strongest. Paste two candidates into the headline tester; the same simulated readers react to both, and Mimiq makes a call: clear, leaning, or too close to call.
On 1,000 real headline A/B tests held out from its development, Mimiq's forecast picked the headline more readers clicked 76% of the time; the best rule of thumb, picking the headline written first, got 61%. That is evidence about headlines in general, not about your community's taste, so read the reasons as well as the call.
What it will not tell you
Whether your launch will take off. Timing, ranking and who happens to be online decide that. Simulated readers are not the people on the forum you post to, and they do not vote.
Whether people will pay or stick around. A flow covers sign-up and the first steps after it, up to the step limit; long-term use needs real users and your analytics.
Questions
Is it free?
Your first test is free: sign in with Google and it starts right away. A free account includes 50 credits, no card. After that, a flow uses 5 credits a person, and it is a $9 Starter (120 credits that never expire) or monthly plans from $49.
Can it test an app on a free hosting subdomain?
Yes, as long as the address is public and has no login or password page in front of it.
Will it create accounts in my app?
Yes, one for each simulated person who gets through sign-up, with a Mimiq email address. Delete them afterwards if you like.
Can it test my launch post itself?
The title, yes, as copy or in the headline tester, and the body of the post as copy. It cannot predict votes or ranking.
My app only has Google sign-in. Will it work?
Not for that step. Simulated people sign up with an email address, not with Google or another account, so if email sign-up is not offered, the flow stops there.
