SaaS Launch Checklist 2026: 60 Steps from Pre-Launch to Week Four

Most launches fail quietly, not dramatically. The page loads slowly on mobile, the share image is missing, nobody can tell what the product does from the tagline, and the analytics were never installed, so the founder cannot tell what worked.

This checklist is designed to stop that. It is written for solo founders and small teams launching a SaaS, web app or AI tool. Work through it in order. Each section ends with a short "done when" so you know when to move on.

Stage 1: Product readiness (2 to 4 weeks before)

You do not need a finished product. You need a product that delivers one clear outcome without breaking.

• Define the one job your product does, in one sentence a stranger understands.
• Make the core flow work end to end: sign up, do the main thing, see the result.
• Remove or hide half-finished features from the main navigation.
• Test sign-up on a phone, with a fresh email, in a private browser window.
• Add a simple way to contact you: email, chat widget, or a feedback form.
• Set up error tracking so you see crashes before users report them.
• Decide pricing, even if it is "free during beta". Unclear pricing kills trust.
• Write a short privacy policy and terms page.

Done when: five people who are not your friends can sign up and get value without your help.

Stage 2: Website and landing page

Your landing page is the destination for every launch link. Treat it as the real product.

• Headline says what it does, not how it feels. "Invoices that chase late payers for you" beats "Reimagine finance".
• Subheadline says who it is for.
• One primary button above the fold ("Start free", "Try it").
• A screenshot or 20-second video of the product in use.
• Three to five benefits, each tied to an outcome.
• Social proof if you have any: beta testers, a quote, a logo.
• Pricing visible or one click away.
• FAQ answering the five questions people ask before signing up.
• Page loads in under 2.5 seconds on mobile. Test with PageSpeed Insights.
• Works without errors in Chrome, Safari and Firefox.

Done when: a stranger can explain your product after 10 seconds on the page.

Stage 3: Analytics and tracking

If you cannot measure the launch, you cannot learn from it.

• Install privacy-friendly analytics (Plausible, Fathom, or Google Analytics).
• Track the key event: sign-up, trial start, or first successful use.
• Create a UTM-tagged link for each launch platform. The free Campaign Link Builder does this in seconds.
• Set up a simple dashboard: visitors, sign-ups, activation, by source.
• Add Google Search Console and Bing Webmaster Tools, and submit your sitemap.

Done when: you can answer "how many sign-ups came from platform X" for any link you share.

Stage 4: Technical SEO and share previews

Every launch link gets shared. Make sure it looks good everywhere.

• Unique page title under 60 characters with your product name and main keyword.
• Meta description of about 150 characters.
• Open Graph image at 1200 x 630 pixels, with your product name and a visual.
• Favicon and a square logo (at least 256 px).
• sitemap.xml and robots.txt that allow crawling.
• HTTPS everywhere, and one canonical domain (with or without www).
• Basic structured data (Organization, SoftwareApplication) if you can.
• An llms.txt file describing your product for AI assistants. See what is llms.txt for why this helps.

Paste your URL into a share previewer to check the title, description and image before launch day.

Done when: your link shows the right title, description and image on X, LinkedIn, Slack and iMessage.

Stage 5: Launch assets

Write these once and reuse them on every platform.

• Tagline under 60 characters.
• Short description of 160 characters.
• Long description of 2 to 3 paragraphs: problem, solution, who it is for.
• Three to five key features as short bullet points.
• Square logo, share image, three to five screenshots at consistent size.
• Optional 30 to 60 second demo video.
• Founder comment: why you built it, what is next, what feedback you want.
• Launch offer if you have one (for example an extended trial).
• A short email for your list and a post for X and LinkedIn.

Done when: you can submit to any platform in under 10 minutes by copy and paste.

Stage 6: Choose and schedule platforms

Do not launch everywhere on one day. Stagger.

Compare platforms in our guides to Product Hunt alternatives and the best startup directories.

Done when: every platform has a date in your calendar and a row in your tracking sheet.

Stage 7: Launch day

• Publish early in the platform's day (many reset at 00:00 UTC or 00:01 Pacific).
• Post the founder comment immediately.
• Share the launch link with your email list, X, LinkedIn and communities, asking for honest feedback, not votes.
• Reply to every comment within an hour, all day.
• Watch errors and sign-up flow; fix anything broken immediately.
• Write down every piece of feedback in one place.
• Do not buy upvotes or run vote rings. Platforms detect them and you can be removed.

Stage 8: The four weeks after launch

The launch spike fades in 48 hours. What you do next decides whether the launch was worth it.

• Email every new sign-up personally within 24 hours.
• Fix the top three problems people reported, then tell them you fixed it.
• Post a short "what I learned from launching" story on Indie Hackers or your blog.
• Submit to evergreen directories and review sites over the next weeks.
• Ask happy early users for a short review on G2, Capterra or your launch page.
• Check which launch links brought activated users, not just visits.
• Plan your next update and a relaunch if the product changes a lot.

The one-page version

If you only have one evening, do these ten:

1. One-sentence description a stranger understands.
2. Landing page with one clear button and a product screenshot.
3. Analytics with a sign-up event.
4. Title, meta description and share image.
5. Sitemap submitted to Google Search Console.
6. Tagline, short and long description, logo and screenshots ready.
7. UTM link per platform.
8. Two or three launch platforms on staggered dates.
9. Reply to every comment on launch day.
10. Email every new user personally.

Frequently asked questions

How far in advance should I prepare a SaaS launch?

Four weeks is comfortable for a solo founder: two weeks to polish the product and landing page, one week for assets and platform queues, and the launch week itself. Queue-based platforms may need longer, so join them early.

What is the best day to launch a SaaS?

Tuesday to Thursday tends to bring more traffic on daily boards but also more competition. Weekends are quieter with less competition. Weekly platforms make the day matter less. Choose the day you can be online and responsive all day.

Do I need a waitlist before launching?

It helps but is not required. A waitlist of even 50 interested people gives you first users and honest feedback on launch day. BetaList and a simple landing page form are the easiest ways to start.

Should I launch before the product is finished?

Launch when the core flow works reliably and delivers one clear outcome. Waiting for every feature delays the feedback you need. You can relaunch later with a bigger update.

How do I measure if my launch worked?

Measure activated users by source, not upvotes. A launch that brought 30 people who use the product weekly beats one that brought 3,000 visitors who never signed up.
