Download ready-to-deploy micro-app templates (polls, dining, tip) with serverless functions optimized for free hosting and WordPress embedding.

Launch micro-apps in two minutes — without a dev bill, complex stacks, or heavy plugins

You're juggling site budgets, DNS confusion, and a to-do list that never ends. You want to validate ideas, add interactive features to WordPress, or spin up a tiny utility (poll, tip calculator, dining recommender) — fast and at zero cost. This Template Pack gives creators downloadable HTML/CSS templates plus tiny serverless functions tuned for free hosting and frictionless WordPress embedding. Deploy, embed, and iterate in minutes — not weeks.

Why micro-app starter kits matter in 2026

Micro-apps — small, focused web tools built for a single task — exploded in 2024–2026 for three reasons: the rise of LLM-assisted coding, broad free/low-cost serverless compute at the edge, and the demand for embeddable utilities that don’t bloat sites.

Speed: Creators can prototype and publish production-ready micro-apps in hours using AI-assisted workflows.
Cost: Free tiers from Cloudflare Pages/Workers, Vercel, Netlify and GitHub Pages now support most micro-app needs for low-traffic projects.
Embed-ability: WordPress block editors, site builders, and headless CMSs accept safe iframe or script embeds — perfect for micro-apps that must live inside existing content.

In late 2025 and early 2026, two trends made starter kits even more valuable: serverless edge runtimes became cheaper and standardized (faster cold starts and better KV stores), and site builders added better iframe and script security policies. That means small creators can run practical apps without complicated backends.

What’s in the Template Pack (quick tour)

Each downloadable template includes:

Static front-end: Minimal HTML and CSS (mobile-first, accessible, WCAG-aware) and a tiny JS module for UI behavior.
Serverless function: One or two file functions (JavaScript/TypeScript) using Web Fetch APIs or Node-compatible handlers, optimized for Cloudflare Workers, Netlify Functions, and Vercel Edge Functions.
Deploy scripts: GitHub Actions or deploy instructions for Pages/Workers, Vercel, and Netlify — built for one-click deploys or quick CLI commands. If you like a local dev toolchain, we also link to guides and reviews (for example, the Nebula IDE review) to speed iteration.
Embed snippets: Copy/paste iframe and WordPress shortcode examples for each template.
Privacy & rate-limit helpers: Example headers, simple input sanitization, and suggestions for GDPR/COPPA compliance. See coverage on cloud cost and rate strategies for low-traffic apps.
Upgrade notes: How to add a real database (Supabase/Postgres), user sign-in (Clerk/Netlify Identity), and paid plans.

Included micro-apps

Poll app — client UI for single-question polls, serverless vote counter, optional anonymous vote tokens.
Dining recommender — quick preference survey on the client, serverless matching logic returning ranked suggestions (example dataset included).
Tip calculator — responsive UI, local persistence, serverless receipt-sharing webhook.
Extras: share buttons, embeddable CSS variables, and a compact analytics ping for your own logging.

How to deploy — three free-host workflows (step-by-step)

Below are concise, repeated-ready deployment steps for the most reliable free hosts in 2026. Choose one that fits your comfort level.

1) Cloudflare Pages + Workers (recommended for edge speed)

Create a GitHub repo and push the template files (index.html, style.css, client.js, /api/vote.js).
Sign up for Cloudflare Pages and connect your repo. Select the build command (none for static) and the output directory (root or /dist).
Deploy the static site. For dynamic endpoints, open Cloudflare Workers and create a Worker using the included serverless file. Use Wrangler (CLI) for quick deploys:
```
wrangler login
wrangler publish api/vote.js --name my-microapp-vote
```
Hook the Worker to a custom route (example: yourdomain.com/api/*) or use a Pages Functions route if you prefer built-in integration.

Test and embed using iframe:

<iframe src="https://your-pages-site.pages.dev/poll.html" style="width:100%;height:380px;border:0;" title="Poll"></iframe>

Why Cloudflare? Consistent edge performance, KV for small vote counters, and a very generous free tier for low-traffic apps. For teams focused on fast edge iteration and publishing, see rapid-edge best practices.

2) GitHub Pages + Netlify Functions (static front-end + simple serverless)

Push index and assets to a GitHub repo and enable GitHub Pages (branch: main, folder: /docs or root).
For serverless, add Netlify site connected to the same repo. Place functions under /netlify/functions.
Deploy. Netlify provides URLs like https://yoursite.netlify.app/. Functions are available at /.netlify/functions/<functionName>.
Embed the static page as an iframe in WordPress or use a script tag that fetches your function endpoint directly from the client.

Why this combo? GitHub Pages is the simplest static host; Netlify Functions fills the serverless gap with minimal setup — ideal if you're familiar with GitHub.

3) Vercel (fast, integrated serverless)

Push the template to a Git repo and connect to Vercel. Vercel detects front-end frameworks automatically, but plain HTML works too.
Place serverless endpoints under /api/*.js. Vercel provides edge-friendly lambdas.
Deploy and embed the published page with iframe or direct script inclusion.

Why Vercel? Simple dev experience and edge functions tuned for fast response. Free tier supports prototype apps well.

Embedding in WordPress — safe, fast, and SEO-aware

Embedding micro-apps into WordPress should be simple and secure. Here are practical, supported options.

Option A: iframe embed (fastest, most compatible)

Copy the provided iframe snippet into a Custom HTML block in the block editor or into classic editor text mode:

<iframe src="https://your-microapp.pages.dev/diner.html" width="100%" height="480" style="border:0;" title="Dining Recommender"></iframe>

Pros: trivial to sandbox, isolated CSS/JS, avoids plugin conflicts.
Cons: not indexed by your site’s HTML, but you can mirror content in accessible markup if SEO matters.

Option B: WordPress shortcode + REST proxy (more integrated)

Create a simple shortcode that loads minimal HTML and fetches data from your serverless endpoint via admin-ajax or the REST API. This keeps the HTML inside your page, improving crawlability for static parts.

// Example shortcode handler (PHP)
add_shortcode('diner_app', function($atts){
  return '<div id="diner-root" data-endpoint="https://your-site.workers.dev/api/recommend"></div><script src="https://cdn.example.com/diner-client.js" defer></script>';
});

Pros: In-page HTML can be crawled; script can progressively hydrate the UI.
Cons: Slightly more setup and requires careful sanitization to avoid XSS.

Option C: Block-based plugin (best UX)

If you plan to reuse micro-apps across posts, create a tiny plugin that registers a custom block. The block stores configuration (endpoint, height, display options) and renders either an iframe or inline markup. The Template Pack includes a minimal block scaffold you can paste into a plugin file.

Security, privacy, and quality-of-service (must-do checklist)

Even small utilities need basic protections. Implement these checks in your templates and deployments.

Input sanitization — Escape user inputs and validate lengths/types server-side.
Rate limiting — Use IP-based rate limits or a token bucket in your edge function to prevent abuse; read hosting cost and rate-limit guidance to avoid surprise bills (cloud per-query cost concerns).
Data retention policy — Don’t keep PII. If you do, document retention and export/delete mechanisms for GDPR/CCPA compliance.
Authentication for advanced features — Use Clerk/Auth0/Netlify Identity when you add personalized features.
HTTPS & CORS — Free hosts provide SSL automatically; set strict CORS policies to allow only your domains.

Performance & analytics for tiny apps

Micro-apps are small, so a lightweight performance and analytics approach is better than full-blown stacks.

Edge caching: Cache read-heavy results at the edge with short TTLs and stale-while-revalidate for instant UX.
Tiny analytics: Use serverless pings to a CSV/KV store or privacy-first analytics providers (Plausible, Fathom-lite) instead of heavy trackers. If you need fully local, privacy-first request handling, check guides on running local desks and pings for analytics.
Progressive enhancement: Ensure core functionality works without JavaScript when it makes sense (e.g., poll fallbacks via forms).

Upgrade path: from free prototype to production

Start on free tiers, then upgrade when you hit traffic, need persistence, or want SLAs.

Keep serverless functions stateless; use KV (Cloudflare) or Supabase for persistent storage.
When storage needs grow, migrate to a managed Postgres (Supabase, Neon) and use the serverless function as an API layer.
Add authentication and monetize with subscriptions (Stripe) behind a simple gateway.
Move DNS to a dedicated provider (Cloudflare or your registrar with advanced DNS) and enable a CDN tier if you need global performance.

Advanced strategies and 2026 trends creators should use

Here are forward-looking tactics to make your micro-apps smarter and more resilient in 2026.

AI-assist for logic: Use guarded LLM prompts for match/recommendation logic (e.g., dining recommender). Keep the LLM at the edge for small inference calls or use a serverless proxy to a managed model to avoid exposing keys client-side.
Edge functions + WASM: For compute-heavy micro-apps (small scoring engines), consider running Rust/WASM modules at the edge for speed and portability — also see notes on edge observability best practices.
Composable embeds: Provide both iframe and JS module versions so site owners can pick isolation vs. synergy with their CSS/JS.
Privacy-first defaults: Default to ephemeral identifiers and anonymized metrics; explicit opt-in for user tracking keeps you compliant and trustworthy. If you want a fully local, privacy-first request desk pattern, see relevant field guides.

Real-world examples & quick case study

Rebecca Yu’s Where2Eat (2023–2024) illustrates the micro-app ethos: a focused app solving one recurring problem for a small group. With AI-assisted prototyping, she built a dining recommender in under a week. Our Template Pack accelerates that process by providing production-ready UIs and deploy scripts, so you don’t rebuild the same plumbing.

"Once vibe-coding apps emerged, I started hearing about people with no tech backgrounds successfully building their own apps." — TechCrunch, reporting trends into 2026.

Download & use: quick checklist (two-minute launch)

Download the Template Pack for the micro-app you want (poll/dining/tip).
Pick a host: Cloudflare Pages+Workers (fast) or GitHub Pages+Netlify (simplest) or Vercel (integrated).
Push the files to a repo and follow the one-click deploy instructions in the pack.
Copy the embed code into a WordPress Custom HTML block or use the provided shortcode.
Test on desktop/mobile and enable simple analytics pings.
When traffic grows, follow the included Upgrade guide: add Supabase, auth, and move to a paid tier.

Common pitfalls and how to avoid them

Overcomplicating the backend: Keep serverless functions tiny. If you find yourself building large APIs, switch to a managed DB and microservice pattern.
Embedding insecurely: Never inject unescaped HTML. Prefer iframe or sanitized shortcodes.
Ignoring quotas: Free tiers have limits. Test load and set rate limits and graceful fallbacks.

Final thoughts — why a template pack helps your site and sanity

Micro-apps are the modern answer to fast validation and feature experiments. The Template Pack removes repetitive setup work so creators can focus on design and value — not hosting invoices or deployment scripts. With edge serverless and improved free tiers in 2026, now is a great time to adopt a micro-app strategy on WordPress and site builders.
