Fork 20 ready-to-run micro apps — dining bots, schedulers, tiny dashboards — with links, run commands and stack notes for fast reuse.

Cut the boilerplate: 20 micro apps you can fork and run in minutes

Spending hours reinventing small utilities that your team needs this sprint? You're not alone. In 2026, teams and solo devs increasingly ship micro apps — tiny, focused pieces of functionality (dining bots, meeting schedulers, tiny dashboards) that solve a single workflow and are safe to fork, extend, or retire.

Below is a curated, practical roundup of 20 open micro apps you can fork today — each entry includes a runnable repo, origin note, tech stack, and minimal run instructions so you can prototype in under an hour.

Trend insight (2026): AI-assisted coding, edge functions, and serverless containers made micro apps cheaper to build and operate. Expect more tiny apps deployed to edge runtimes (Vercel Edge, Cloudflare) and packaged as single-purpose GitHub repos with CI/CD templates.

How to use this roundup

Fork any repo, read its LICENSE (most listed are MIT/Apache), then clone and run the quick-start commands. For tools to help internal organizing and runbooks see our tools roundup.
Prefer deploying to serverless/edge if you want near-zero ops: Vercel, Netlify, Cloudflare Workers, or Fly.io. For hybrid and edge deployment patterns, see hybrid edge workflows.
Use the security checklist below before sharing externally (secrets, rate limits, dependency checks).

20 Forkable micro apps — quick list

Selected deep dives (runnable instructions + snippets)

1. Dining Bot — quick verdict

Purpose: Solve group decision fatigue. Origin: inspired by Rebecca Yu's Where2Eat story and now packaged as a simple chat bot with optional LLM integrations. Tech: Node.js + Slack/Bot Framework, lightweight DB (SQLite), optional OpenAI integration.

Repo (fork and run): github.com/codenscripts/dining-bot

Run locally:

git clone https://github.com/codenscripts/dining-bot.git
cd dining-bot && npm install
cp .env.example .env (set SLACK_BOT_TOKEN, SLACK_SIGNING_SECRET, optional OPENAI_API_KEY)
npm run dev

Core bot handler (simplified):

import { App } from '@slack/bolt'

const app = new App({ token: process.env.SLACK_BOT_TOKEN, signingSecret: process.env.SLACK_SIGNING_SECRET })

app.message(/where to eat/i, async ({ message, say }) => {
  const options = await getNearbyOptions(message.user)
  await say(`How about: ${options[0].name}? (Pick to lock in)`)
})

await app.start(process.env.PORT || 3000)

Notes: Replace getNearbyOptions with your preferences DB or an LLM prompt. Deploy to Vercel or Fly.io; see edge-first patterns and hybrid edge workflows for deployment strategies. Use env vars in platform settings.

2. Light Meeting Scheduler — Calendso (practical fork)

Purpose: Personal scheduling with calendar integrations. Tech: Next.js, PostgreSQL, and OAuth integrations. Calendso is production-grade and easily forkable for internal teams.

Repo: github.com/calendso/calendso

Run notes: Use Docker for quick local Postgres; follow repo README for OAuth redirect URIs. For a minimal internal-only version, mock calendar APIs with environment toggles and run on an internal domain.

3. Mini Dashboard — metrics at a glance

Purpose: Small single-page dashboard to display a few metrics (uptime, deployments, errors). Tech: Svelte or React frontend, simple JSON API (Express), persisted to flat JSON or SQLite.

Repo: github.com/codenscripts/mini-dashboard

Run locally:

git clone https://github.com/codenscripts/mini-dashboard.git
cd mini-dashboard
npm i
npm start # serves backend api on /api/metrics and static UI

Example API route (Express):

app.get('/api/metrics', (req, res) => {
  res.json({ uptime: process.uptime(), lastDeploy: '2026-01-10T12:00:00Z' })
})

Why these micro apps matter in 2026

Smaller blast radius: Micro apps have limited scope, making security reviews and compliance easier. In 2026, teams prefer tiny, audited apps they can control rather than large monoliths.

AI-assisted prototyping: LLMs and copilots reduced the time to produce working prototypes. Many repos now include AI prompt docs or optional LLM integrations for personalization or fuzzy matching (restaurants, availability, recommendations).

Edge and serverless defaults: Most micro apps ship with deployment templates (Vercel, Cloudflare, GitHub Actions) so a developer can fork and deploy in minutes. See edge-first patterns for recommended architectures.

How to fork responsibly — a short checklist

Check the license: MIT/Apache are easiest for internal forks. Avoid ambiguous or restrictive licenses for commercial use.
Scan dependencies: Run Snyk, npm audit, or GitHub Dependabot before running in production. Use the security checklist (privacy & security guidance).
Remove secrets: Ensure .env files and test tokens are not committed. Rotate any leaked keys.
Rate limits & abuse: Add basic throttling and request validation for public endpoints.
Minimal observability: Add logs and a small metrics endpoint (/metrics) that your monitoring can scrape. For storage & cost guidance around logs, see the CTO storage playbook (storage costs guide).

Deployment patterns that make forking painless

One-command deploy: Repos include templates for Vercel or Netlify with required env var hints. Pair these with internal runbooks from our tools roundup.
Containerized for portability: Dockerfile + fly.toml for Fly.io makes an app deployable to multi-region edge containers. See recommended edge-first patterns.
Edge functions for low-latency: Use Deno Deploy or Cloudflare Workers for bots and read-heavy dashboards; these are covered in edge-first patterns.
Serverless for cost-efficiency: Use AWS Lambda or Google Cloud Functions for event-driven micro apps.

Security and privacy notes (must-dos)

Encrypt sensitive data at rest; treat internal user data as PII.
Use short-lived tokens and rotate often. Prefer OAuth scopes that are minimal.
Protect webhook endpoints with signatures (Slack, GitHub, calendar webhooks).
Apply Content Security Policy (CSP) and sanitize user input on forms and chat inputs.

Advanced strategies — extend a micro app into a product

Start small, then iterate via these tactics:

Feature flags: Keep the core app lean and gate heavier features (LLM suggestions, calendar sync) behind flags.
Composable integrations: Expose small webhooks and a straightforward API so other internal tools can consume the micro app.
Multi-tenant design: If you expect internal teams to adopt, add tenancy early to avoid costly migrations.
Telemetry-first UX: Add minimal analytics to understand how the micro app is actually used before expanding features.

Community contributions and best practices

When forking a micro app to contribute back, follow this lightweight workflow:

Create a branch for a single, small change.
Include a minimal test and update the README with running steps.
Document security impact and add a migration section if data schema changes.
Open a PR with context and attach a short demo URL (Vercel preview links are excellent).

Practical takeaways — what to fork first

If you need team coordination fast: fork Dining Bot or Standup Bot and integrate with Slack/Teams.
If you need scheduling: fork Calendso or the Meeting Room Booker for a scoped internal deployment.
If you want a deployable starter: fork the Micro App Archetype — it includes GitHub Actions and a Vercel template.

Final notes on maintenance and discoverability

Document the run steps and add a very small demo (link to a Vercel preview or screenshots). In 2026, discoverability depends on good README, clear license, and a short demo video or GIF. Keep PRs small, keep issues annotated with expected impact, and add a CODE_OF_CONDUCT if the repo accepts external contributions.

Closing: fork, run, iterate

Micro apps are the low-friction way to solve specific problems without inflating your stack. Use the curated list above to fork working examples, learn by reading minimal code, and ship a polished internal tool in days — not weeks.

Actionable next steps: Pick one app above, fork it, run the quick-start commands, and deploy to a preview environment (Vercel or Fly.io). Apply the security checklist before sharing outside your org.

Want a ready-to-run bundle? We maintain a starter collection and CI templates on our GitHub — fork the Micro App Archetype and you’ll have a deployable micro app scaffold in under 10 minutes.
