Micro-SaaS by distribution: six ways the first customers arrive
Micro-SaaS lives or dies on distribution, so the 52 ideas below are grouped by where their customers are found rather than by industry. Each group shows how products there earn, the main risk, who is already there and a founder's read, with idea counts, difficulty, MRR and build-time ranges calculated from our research.
Embedded widgets & scripts
10 ideas7 easy · 3 medium$3K–$25K MRRMVP 2–6 weeks
Products that live on a customer's own website or app: changelogs, testimonial walls, social-proof pop-ups, cookie consent, status pages, waitlists, lightweight heatmaps and form analytics.
- How it makes money
- Monthly plans tiered by traffic, embeds or seats, usually with a free plan that carries your branding.
- Main risk: Medium
- Anything that sets cookies or records visitor behaviour runs into consent law such as GDPR, and a script that slows a customer's page gets removed.
- Already there
- Beamer, Senja, Cookiebot, Hotjar, Instatus
Founder's read: The widget is its own advert: every free install shows your badge to someone else's visitors. Tally, a form builder that grew this way, reached $5M ARR in April 2026 with 11 people and no outside funding, converting about 2% of free users to paid — and now reports that AI search has overtaken the badge as its biggest channel.

Developer APIs & monitoring
9 ideas7 easy · 2 medium$2K–$25K MRRMVP 1–6 weeks
Small, dependable services developers wire into their stack: uptime, cron, SSL and domain monitoring, webhook testing, screenshot and social-image APIs, API playgrounds and commit-message tooling.
- How it makes money
- Usage tiers — checks, calls, renders — with a generous free tier; developers upgrade when a team or production workload depends on it.
- Main risk: Medium
- Reliability is the product: a monitor that misses an outage loses trust at once, and cloud providers and GitHub keep shipping free versions of simple tools.
- Already there
- UptimeRobot, Cronitor, Healthchecks.io, Webhook.site, URLBox
Founder's read: The most proven home for one-person SaaS. Healthchecks.io, a cron-job monitor, had 652 paying customers and $14,043 MRR in July 2024, run part-time by one developer who keeps the free plan generous on purpose. The ceiling is modest and the growth slow, but developers who rely on a tool rarely leave it.

Platform add-ons
4 ideas2 easy · 2 medium$2K–$30K MRRMVP 2–6 weeks
Tools that live inside another product and are found through its marketplace or community: Slack bots, Notion-powered websites, Google Sheets dashboards and WordPress maintenance.
- How it makes money
- Per-workspace or per-site subscriptions, billed directly or through the platform's marketplace.
- Main risk: High
- You depend on one platform's API, review process and roadmap — a policy change or a new native feature can erase the business.
- Already there
- Geekbot, Super.so, ManageWP, Looker Studio
Founder's read: The marketplace hands you buyers who are already searching, which makes the first hundred customers the easiest to reach in micro-SaaS. The price is concentration: build on a platform whose API has been stable for years, and collect customer emails so the relationship is yours rather than the platform's.
Search-led utilities
13 ideas12 easy · 1 medium$2K–$30K MRRMVP 1–6 weeks
Single-job tools people look up by name: broken-link and meta-tag checkers, privacy-policy, invoice and email-signature generators, favicon, QR-code and colour-contrast tools, time-zone and meeting-cost calculators, link redirects and PDF forms.
- How it makes money
- A free tool captures search traffic; revenue comes from the recurring version — saved history, bulk use, monitoring, API access, teams or white-label.
- Main risk: Medium
- Free versions already rank for most of these searches, and AI answers now resolve the simplest ones without a click.
- Already there
- Screaming Frog, Termly, WiseStamp, Bitly, RealFaviconGenerator
Founder's read: Several ideas here are features, not businesses — a favicon, contrast or time-zone tool will struggle to charge when free ones rank first. They work as the top of a funnel: rank the free tool, then sell the recurring job (monitoring links every week instead of checking once). Content can carry the whole company: Plausible Analytics reached $1M ARR in June 2022 with a team of four and never paid for advertising.

Creator & marketer AI tools
10 ideas8 easy · 2 medium$3K–$30K MRRMVP 2–6 weeks
Writing and publishing help for people who market themselves: post writers and schedulers, blog ideas and outlines, tweet-to-blog repurposing, alt text, subject-line testing, affiliate links, link-in-bio pages and content calendars.
- How it makes money
- Low monthly subscriptions, often with caps on AI generations.
- Main risk: High
- General-purpose assistants do most of this writing for free, and social platforms restrict API access and automation.
- Already there
- Typefully, Taplio, Hypefury, Linktree, ChatGPT
Founder's read: The easiest group to build and the easiest to copy. What lasts is what a chat window does not have — a creator's own past posts and results, publishing tied to performance — and distribution you already own, because buyers here pick tools from the people they follow.
Niche B2B workflows
6 ideas3 easy · 3 medium$2K–$30K MRRMVP 2–6 weeks
Focused tools for one clearly defined business buyer: client feedback for agencies, job boards for community owners, competitor price tracking for online stores, cancellation flows for subscription businesses, launch checklists for founders and recurring invoices for freelancers.
- How it makes money
- Higher monthly prices per account; cancellation-flow tools can also charge on the revenue they save.
- Main risk: Medium
- With fewer customers each lost account matters, and the biggest threat is a larger suite adding your feature.
- Already there
- Churnkey, Prisync, Filestage, Niceboard, FreshBooks
Founder's read: Fewer customers at higher prices is often the quickest route to meaningful monthly revenue. Because you can name the buyer, you can go and find them — in their communities, their tools' marketplaces and their inboxes — instead of waiting to be found.
