FAQ
Frequently asked questions
What is Mostra?
Mostra is a public 3D wall where independent makers, vibe coders and early-stage startups put up posters for their products, apps, tools and experiments. Visitors browse the wall, open a poster, and click through to the maker's own website. Each product is a poster put up for 30 days. Every poster has its own page at https://mostra.onemilliontools.com/post/<slug> that links to the product's website.
Which products fit?
Independent software products, apps and experiments, many of them AI-powered, from any maker. Categories follow familiar app-store types: Productivity, Developer Tools, Graphics & Design, Photo & Video, Music & Audio, Education, Business, Utilities, Social, Lifestyle, Health & Fitness, Entertainment, Games, Other. Misleading, unlawful, adult or spam posters are removed.
How does a poster help my product get seen?
Visitors browse the wall and click posters that catch their eye. Each poster also gets its own indexable page with a title, description, share preview image and structured data, and is listed in its category page, the sitemap and https://mostra.onemilliontools.com/llms.txt so search engines and AI assistants can find it. The page is a ready-made link to share, and you get view, click and like counts for every poster. It does not guarantee traffic: how many people see a poster depends on the product, the poster and how you promote it. Links from poster pages are marked rel="ugc nofollow" (rel="sponsored nofollow" for protected, paid posters), so do not count on them for search ranking; the value is direct visitors and a presentable page.
How long does a poster stay on the board?
A free poster stays for 30 days. It then leaves the wall, but its page stays reachable. Paying for protection adds 30 more days, and a poster that has left can be brought back the same way.
What does it cost?
Putting a poster up is free and stays on the wall for 30 days. Protection costs USD 9.99 once and adds 30 more days: the poster is placed with priority so free posters do not cover it, and it is marked as protected. A person has to pay on the website; agents cannot pay.
What are the limits?
Each account can have 3 free posters on the board at a time, and one poster per product website. At most 5 posters per day, and one poster per 10 minutes. The same limits apply to agents.
How can an AI agent publish for me?
Sign in at https://mostra.onemilliontools.com/me, open "Connect an AI agent" and create an API key. Add the MCP server https://mostra.onemilliontools.com/mcp to your agent (Streamable HTTP) with the header "Authorization: Bearer <key>". The agent can then use publish_product, list_my_posters, get_share_text and get_badge_html. Without a key it can still read the FAQ and search the board. Keys can be revoked at any time.
What does the agent need to give the tool?
A title (2-80 characters), a description (10-240 characters), a category, the product's website (https), and a poster image. The image can be passed as image_url or image_base64; if neither is given, the website's own preview image (og:image) is used. Images must be PNG, JPEG or WebP, up to 5 MB, with a width-to-height ratio between 1:2 and 2:1. A poster that is at least 800 px wide looks best.
Does a person stay in control?
Yes. A person creates the key and can revoke it. Agents are instructed to show the poster to the user and get approval before publishing. Posters made through an agent are labelled on their page. The account owner is responsible for what is published with their key.
How do I get more exposure after publishing?
Share the poster publicly (get_share_text gives a ready text with the poster link), put the badge from get_badge_html on your own website so visitors can find the poster, and consider protecting the poster for 30 more days around a launch. Add your best poster image: posters with a clear screenshot or product visual stand out on the wall.
Can a poster be edited or removed?
Published posters cannot be edited, so check them before publishing. To have one removed, email hello@onemilliontools.com from the account's address.
