From the r/SAASbuild floor
We dropped a single prompt into r/saasbuild — “What are you building?” — and stepped back. What came back was a snapshot of where indie software actually lives right now: open-source infrastructure tools, AI-native products, solo experiments, and a few things that don’t fit any category yet.
This is not a curated list of funded startups. It’s builders in motion — some launched yesterday, some have been quietly shipping for months. A few are making money. Most are not yet. All of them are making something.
We’re featuring every project that showed up. No filters for stage, polish, or funding. If you built it and dropped it in the thread, it’s in here.

Regen by FluidifyAI
Open Source · Infrastructure
A self-hosted, open-source oncall management suite that replaces PagerDuty, incident.io, and Rootly at zero cost. Handles alerts, incidents, and AI-generated post-mortems. Bidirectional sync with Slack and Teams. Works out of the box with Prometheus, Grafana, and Datadog.
Production-ready and tested. BYO-AI.
● Production ready
aislop
OSS · CLI · Code Quality
A code quality gate built specifically for AI-generated code. Catches what agents like Claude Code, Cursor, and Codex quietly leave behind: dead code, swallowed exceptions, any casts, hallucinated imports. 50+ rules across 8 languages. Sub-second. Fully deterministic. Nothing leaves your machine.
npx aislop scan— that’s the whole install.

Code Pet
Electron · Claude Code
github.com/mradovic95/code-pet
A tiny animated pet that lives in the corner of your screen and reacts to what Claude Code is doing. Sleeps when you’re idle, gets to work when you send a prompt, holds a thinking pose in plan mode, and looks up at you whenever Claude needs your input. Tracks every skill and MCP tool you call, locally. No telemetry. Never leaves the machine.
Long AI coding sessions feel a bit lonely.
◐ v0.1.x · actively developed
Taskosaur
Open Source · Project Management
An open-source project manager where the AI actually does the work instead of just chatting about it. The premise is simple and the distinction is real: most AI-integrated PM tools are chat wrappers. This one ships tasks.
◐ Early stage
IslandPulse
Webhooks · Local AI
Turns your data into live activity updates with a single webhook call. Ships with Nyth AI, a privacy-first local LLM that runs entirely on your device. No signups, no server, no analytics. One webhook in — live updates out.

CuteMarkets
API · Fintech
An affordable US stocks and options market data API built for algo trading devs and backtesting workflows. Reproducible market data without the enterprise price tag.
● Live
SaaS Clone Scanner
Automation
Scans SaaS products, compares them against open-source alternatives, identifies what each does best, and rebuilds a composite version. Also sells “Project Harvesting Protection” for $49.99/month — a product category that did not exist before this builder invented it.
◐ In development
Adtention
Ad Network · Claude Code Plugin
A Claude Code plugin that shows small status-line ads while you code, so you earn while you build. The plugin is the first app on an underlying ad network that powers a prompt-to-earn model.
◐ Early
LocalePush
Mobile Dev · i18n
Helps mobile developers localize their app metadata and App Store screenshots instantly. Removes one of the quietest time sinks in mobile app publishing.

Growth Constraint Intelligence
GTM · Revenue
A platform that finds the bottleneck limiting revenue growth for SaaS companies post-PMF. Combines internal and external business signals to diagnose what’s actually slowing growth — before recommending where to deploy capital and attention. Built by a GTM consultant of three years, now translating the practice into software.
Most companies respond to slowing growth by hiring salespeople. We diagnose the actual bottleneck first.
◐ Validation stage
AppImp
App Store Intelligence
Surfaces what App Store users actually complain about. If you’re building a competing app or improving an existing one, this tells you what the market has already said about your category.
● Live
Zero to Sale
Sales · SaaS

◐ Early
Vibe Promote
Marketing Automation

◐ Early
Home Estimate Tool
Home Services · B2C
A customer-facing quoting tool for home service businesses. Homeowners answer a few questions and get a rough budget range before calling for an estimate. Built to filter price shoppers, set realistic expectations, and save contractors time on estimates that were never going to close.
◐ In development
— Productivity
Packd
Cross-platform · Setup
Install all your apps in one click. Pick what you want, download one installer, it runs your system’s native package manager — winget, Homebrew, or Flatpak. Shows you the exact commands before anything runs. No bloatware, no sketchy mirrors, no “Next Next Finish.” Works on Windows, macOS, and Linux.
● Live · three platforms
Discipline Forge
Habits · Self-development
An app for building discipline and habits. The name does more work than most habit apps do.
◐ Early
HiringFunnel
AI · Job Search
Automates the process of applying to remote jobs. AI-driven, built for job seekers who are spending more time applying than working.
● Live
Shaflex
Social Publishing
A simple, flow-first app for cross-platform social media publishing. The emphasis on “flow-first” suggests an interface designed around the act of writing, not the act of scheduling. Worth watching as a design-led entrant in a market full of dashboard-heavy tools.

Dhwanika
Music · AI · DAW
An AI-enabled DAW engine. Music production tooling with AI wired into the core — not bolted on afterward.
◐ In development
— Education
QueryCase
SQL · Learning
Teaches SQL through detective-style investigations. Instead of disconnected exercises, you solve cases by writing real SQL against live databases — each case has a mystery, suspects, and clues hidden in the data. DuckDB runs entirely in the browser, so queries execute instantly without a backend. Launched last weekend and hit 50+ users.
50+ users in the first weekend. The learning experience is the product.
● Just launched
Gyanova
AI Tutor · Edtech
Enter a topic. The AI builds a structured curriculum, pulls accurate information from textbooks, Wikipedia, and the web, decides how to visualize each section (charts, boxes, tables, flows), and generates animated slides where narration triggers animations as it plays. Multiple narration styles. Currently waitlisting.
◐ Waitlist
JSI — Jobseeker Intelligence
Career · AI
Described as the most comprehensive AI-assisted platform for jobseekers available today. Covers the full arc from discovering opportunities to preparing for interviews.
● Live
— Security
BugBuzzer
Security · SaaS
External security scanner for web apps — finds security holes, data leaks, and critical bugs before your users do. Built for vibecoders and SaaS founders in the growth stage. The pitch cuts straight to the problem: builders are shipping faster than ever, and most of what gets built is still broken in ways that only surface when users hit them.
● Live
— Health & wellness
AllTails Care
Pet Health · Mobile
Centralizes pet care: routines, health logs, analytics, multi-species support in one mobile app. Share with the whole family and caregivers. Export data directly to vets. No AI integrations yet — and sometimes that’s the right call.
● Live
some2eat
Dietary · AI Recipes
A web app that finds the intersection of foods that are generally tolerable across multiple health conditions — with a shopping list, and AI-generated recipes in the premium tier. Built for people who have to manage more than one dietary restriction at once, which is more people than most apps account for.
● Live · freemium
Walk Mate: Daily Routes
iOS · Health
An iOS app that generates a random walking route in your location every day. Simple premise. The kind of app that just works and doesn’t need to be more than it is.
