Does your pitch fit?

One sentence has to work in four places with four different limits. Type yours and see where it runs over. Nothing you type leaves this page.

    [ 02 ] Why this exists

    Every channel has a rule that bites on launch day.

    These six came from launching two small products in autumn 2026. Slipway puts the rule on the channel's card, with the date it was last checked, before you write a word.

    1. 01

      Free subdomains get turned away

      Some directories refuse a product that lives on a netlify.app or vercel.app address, and one wants an email on your own domain.

    2. 02

      New accounts can't post yet

      Indie Hackers holds publishing back until a new member has left a few real comments.

    3. 03

      No generated text

      Hacker News asks that posts and comments be written by a person. Slipway gives you a fact sheet to write from, not a draft.

    4. 04

      Launch windows have a weekday

      Peerlist's Launchpad runs by the week and opens on Mondays. Miss it and you wait seven days.

    5. 05

      "Free" has a condition

      A free listing can require a backlink on your site first, or put you in a queue weeks long.

    6. 06

      Indexing has a quota

      Search Console's Request indexing runs out for the day. Submit the sitemap first and spend requests on pages that matter.

    Rules change. Every card in Slipway shows when it was last checked and links to the channel's own page.

    [ 03 ] What's on the page

    Six tools, one tab.

    Copy desk

    Write the pitch once. Slipway lays it against each channel's limits: tagline, title, post, description. You see what fits and what is over, live.

    Channel cards

    One card per place you launch: what it accepts, what it refuses, image sizes, best time to post, and your status there.

    Preflight

    A check before you post: free subdomain, missing alt text, a title over the limit, a link with no tag.

    Ref links

    Slipway adds a ?ref= tag per channel, so your analytics show which post sent each visitor.

    Numbers log

    Visits and sales by channel, typed in by you, on one small table. You see what worked before launch two.

    Yours, as a file

    Everything stays in your browser. Export the whole launch as Markdown and keep it in your notes, your repo or your vault.

    [ 04 ] How a launch runs

    Down the slip in three steps.

    1. 01

      Write it once

      Name, tagline, one-paragraph pitch, link. Ten minutes.

    2. 02

      Pick your channels

      Tick the places you'll launch. Each card shows its rules and what it needs from you.

    3. 03

      Work down the page

      Copy, paste, post, tick. You post with your own hands; Slipway keeps you inside the rules.

    [ 06 ] FAQ

    Straight answers.

    Can I use it today?

    Not yet. Slipway is being built. The pitch fitter on this page works now; the rest opens to the founding list first.

    Does it post for me?

    No, and that's on purpose. Several communities want a person behind each post, and accounts that automate get limited. Slipway prepares everything and you press the button.

    Where does my launch data live?

    In your browser. There is no account and no server holding your copy. Export to Markdown whenever you want a backup.

    Why a one-time price?

    You launch a few times a year. A monthly bill for that makes no sense, so Pro is a single payment through Gumroad with a license key.

    Who makes it?

    Vibelab, a one-person studio that also makes InvoiceForge (free invoicing) and Snapgloss (screenshots that look designed). Slipway is the tool those two launches needed.
