Pay once for the full, unminified TypeScript source, agent setup guides and automated tests. Run and modify the code on your own stack, with no recurring Helpful Mods licensing fees.

BEST VALUE · SAVE $200
A complete B2B SaaS core for $199.
Skip months of core plumbing. Get five flagship mods—Funnel and Revenue, Paid Membership and Teams, Onboarding Journeys, In-app Notifications, and Customer Support—pre-integrated into a single working application with accounts, workspaces, billing, and projects already wired together. $399 standalone value, yours for $199.
SHIP FASTER
Your agent will build the version that works when everything goes right. These mods handle what happens when it doesn't.
Booking & Calendar
Lock in appointment slots while customers pay their deposit and auto-release them if they walk away. Google Calendar busy-time checks, event updates, and reminders come wired in—and late payments get flagged instead of causing a double-booking.
Funnel & Revenue
Connect signup, resumable Stripe Checkout, and app permissions into one payment and access workflow. Provision access on verified payment, bring buyers back to interrupted checkouts, and pause access when billing or risk checks require review.
Paid Membership & Teams
Give customers multi-tenant workspaces, role permissions, ownership transfers, and expiring email invites that reserve seats and check the team’s paid Stripe subscription before granting access.
Workflow Automation
Every step saves its progress, so a failed job picks up right where it stopped. If an external API times out, the workflow pauses for your review instead of blindly repeating a payment or email.
Recurring Writing
Turn your rough notes and source material into scheduled newsletter or article drafts that follow your voice, check against your past archive for repetition, and wait in a review workspace for your sign-off.
Website Chat
Deploy an embeddable sales and support widget that checks answers against your approved business facts, with source links and account and billing actions kept outside the assistant. Capture leads and let staff reply in the same conversation.
WHY HELPFUL MODS
Ask an LLM to build Stripe billing or appointment booking from scratch and you can get a great-looking demo. Then a webhook fires twice, a customer refunds half an order, or two users book the 2:00 PM slot at the same second. Every mod is engineered and tested against those production failure modes, so your coding agent starts with the hard part already done.
A boilerplate starts with its own framework, database and application structure. Helpful Mods are modular backend services that connect to the app you already built—Next.js, Rails, Python, Laravel or Go—over HTTP APIs. Starting from a blank repo? Get the five-mod Foundation Kit for $199, with accounts, workspaces and billing already connected.
WHAT’S INSIDE THE DOWNLOAD
Every mod includes complete, unminified TypeScript and Node.js source code. When you unzip a mod, your coding agent gets:
Clean, unminified code and database migrations you can inspect, modify and run on your own infrastructure. Full ownership of your deployment, with no SaaS lock-in.
README.md & setup/SKILL.mdStep-by-step setup instructions for Claude Code, Cursor, Codex, Windsurf, or your coding agent of choice.
Structured error maps in setup/error-reference.json and the included agent guide help Cursor, Claude or Codex diagnose setup problems and work through the fix in your repo.
Checks for the mod’s workflow, database rules, and recovery behavior, so your agent can test the connection before you go live.
When should a customer get access?
I’ll connect the Stripe checks, access rules and recovery steps.
Built-in prompts guide your coding agent.
Your agent can take it from here
You get the complete source code, an agent setup prompt, an integration guide, and an automated test suite. Just point your coding agent at the folder—it reads the architecture, wires the mod into your app, and runs the verification checks for you.
Evaluating how our code runs in production? Mallow—our support assistant in the bottom corner—is powered directly by our Website Chat mod. If you have a specific question about stack compatibility or bundle fit while browsing, ask it there, or grab the exact source code powering it in two clicks.
Built with clean TypeScript, Node.js, and PostgreSQL (or SQLite for Website Chat). Each mod runs as a lightweight standalone service alongside your app, so you can keep your existing stack. Your agent connects it using the included integration guide, and each product page lists the hosting requirements upfront.
How to install a purchased modSee what it does, what it needs, and how it fits your project.
The included prompt points your agent to the source, setup guide, and answers to common problems.
Your agent connects your accounts and your app, then runs the built-in test suite to put the full workflow through its paces.
