LX AI Tool Directory is a curated index of 140 vertical AI micro-SaaS tools built and operated by a one-person factory, LX AI Micro-SaaS Factory. Every entry links to a live, working product rather than a marketing landing page, so you can open a tool and get output in seconds.
A vertical AI micro-SaaS is a small, focused product that solves exactly one narrow job for a defined buyer - a GDPR policy generator, a red-team scanner, a SQL fixer - instead of a broad suite. LX ships about 139 of these across 18 tight buyer-intent verticals.
Every tool listed is a real, running product that the one-person factory built, deployed, and validated against its core job before it goes live. Tools are grouped by the job they do, not by hype, and there is no paid placement or sponsored ranking anywhere in the index.
Most tools show transparent monthly pricing starting around $9, and several offer a free tier or free trial. Each tool page lists live pricing before you click through, and no signup is required to open the tool and try its demo.
The directory is privacy-first (Umami analytics, no Google tracking, no ad cookies), ad-free, and built in public by a single founder. Methodology and stack are stated openly, and only live products are listed - parked or placeholder pages never make it into the index.
Rankings are non-personalized and never paid.
The directory and its tools are built to these public standards and official docs.

LX AI Tool Directory is a curated index of 139 vertical AI micro-SaaS tools built and run by a one-person factory, LX AI Micro-SaaS Factory. Each entry links to a live, working product so you can try it in seconds.
It is a small, focused product that solves one narrow job for a defined buyer - for example a GDPR policy generator or a SQL fixer - rather than a broad software suite. LX ships about 139 of these across 18 verticals.
Every listed tool is a real, running product the factory built, deployed, and validated against its core job before going live. Grouping is by job-to-be-done, with no paid placement or sponsored ranking.
Most list transparent monthly pricing starting around $9, and several offer a free tier or trial. Each tool page shows live pricing before you click through, and you can open the demo with no signup.
Pricing is set per tool and shown on each tool page. The directory spans free, low-cost (under $10/mo), mid ($10-29/mo), and higher tiers; a pricing overview by tier is listed on the homepage.
Tools are updated as the factory ships improvements, and the directory is rebuilt on every change. The homepage shows a Last updated date reflecting the most recent build.
Yes. The factory adds verticals as it ships them and welcomes suggestions. Reach the founder via the email on the About page and the directory footer.
LX AI Tool Directory is built and maintained by Xingliang Li, founder of LX AI Micro-SaaS Factory. Contact is via the email listed on the About page and the site footer.
The directory is built to public standards including WCAG 2.2 and the ADA, and uses privacy-first analytics (Umami) with no Google tracking. Individual tools such as A11yGuard are built around WCAG and ADA checks.
Rankings are non-personalized and never paid. They weigh job-to-be-done match, category fit, price transparency, freshness, and availability of a live product - the same factors shown on the homepage.
The lowest monthly price in the LX directory is $9/month, and most tools sit between $9 and $29/month. Every listing shows its live monthly and annual price before you click through, so you can compare cost without opening 139 tabs. Annual plans are typically 15-20% cheaper per month than paying monthly.
Prices range from $9 to $79 per month across the 139 live tools. The $9-$19 band covers single-task utilities (invoice generation, schema validation, email workflows). The $29-$59 band covers governance suites such as AIActRadar ($59/mo) and AgentPolicy ($29/mo). AgentRedTeam sits at $79/mo as the full red-team harness.
For EU AI Act readiness, AIActRadar ($59/mo) turns regulatory obligations into a prioritized compliance roadmap. For the adjacent need of policy documentation and agent governance, AgentPolicy ($29/mo) covers policy-as-code. For adversarial testing of your own agents, AgentRedTeam ($79/mo) is the dedicated harness. A11yGuard ($29/mo) covers the separate concern of WCAG/ADA accessibility on AI-generated frontends.
Developer Tools is the second-largest vertical here with 19 live tools. The cheapest entry points are single-purpose validators and generators in the $9-$19 range. For teams that need governance rather than throughput, AgentPolicy ($29/mo) adds policy-as-code on top of an existing dev stack.
Most are paid with transparent monthly pricing starting at $9; some offer a free tier or a contact-based enterprise plan. There is no hidden pricing: each tool page shows the live price, the annual option, and what the paid tier unlocks before you commit.
Start from the vertical that matches the job rather than the brand name - the directory groups 139 tools into 18 verticals by what they do. Then filter by monthly budget (most single-task tools are $9-$19) and check the tool page for whether it needs live AI API access or runs in demo mode. If two tools look interchangeable, open both: each links straight to the running product, so you can test in seconds rather than reading comparison tables.
All 139 are live, running products on their own subdomain (for example aiactradar.lxsaihub.com) - there are no mockups or waitlist stubs. Each listing links directly to the working product, and pricing is shown on the page rather than hidden behind a sales form.
A micro-SaaS is a narrow, single-job product that runs on someone else's infrastructure and costs a flat monthly fee - typically $9-$29 for a single-task tool. A custom internal script costs engineering time to build and maintain, and has no vendor support. The trade-off is control: micro-SaaS gets you a maintained product immediately, while a script gives you data ownership but no updates.
These are decision-support and drafting tools, not legal, financial, medical, or security advice. Do not rely on them as a substitute for a qualified specialist, and have a human review any output tied to a regulated, financial, or life-safety decision.
LX is for solo founders, indie hackers, small teams, and agencies who need a narrow, ready-to-use AI capability without building it from scratch or buying a broad, expensive suite. If you want a single-task tool you can open and try in seconds - a compliance check, a billing helper, a schema validator - LX is built for you.
The tools that get you found by Google and by AI answer engines — content briefs, brand visibility, captions.
Red-team, audit and compliance tooling for teams shipping LLM agents into production.

Do not treat LX listings as a substitute for a qualified specialist. These are decision-support and drafting tools, not legal, financial, medical, or security advice. If you are an enterprise that needs SSO, custom SLAs, on-prem hosting, or a SOC 2-audited vendor, a custom build or an enterprise platform will fit better. And if a task is life-safety or regulated-critical, have a human expert review every output before you act on it.
