UND-RDR

Find the GitHub repos people will be talking about next.

UND-RDR is a live discovery index for underrated open-source projects: 1,000 active repos under 1,000 stars, ranked for momentum, usefulness, and that "wait, why is nobody talking about this?" feeling.

Why It Exists

GitHub is enormous. The best small projects usually do not look famous yet: they have a sharp README, a weirdly useful idea, a burst of stars, a maintainer shipping fast, or a niche that suddenly starts mattering.

UND-RDR watches for those signals and turns them into a fast, editorial browsing surface.

What Makes It Interesting

• Spotlight first: the default feed prioritizes momentum-heavy, near-1K, recently active, high-signal repos.
• Actually under the radar: the active shelf stays under 1,000 stars, with graduates preserved separately.
• Fast discovery loops: open a repo, inspect signal, jump to related projects, save it, keep going.
• Useful categories, not taxonomy cosplay: AI Agents, MCP, Memory / RAG, Local Models, macOS, Browser Automation, Dev Tools, Security, Data / Docs, and Voice / Media.
• Private collecting: GitHub sign-in unlocks a personal Watchlist and named Collections without touching the public dataset.
• Reviewed data flow: public submissions create review issues; automation opens PRs instead of quietly mutating production data.

Product Tour

Surface	What it is for
Discover	The main feed: spotlight, Fresh, Rising, Hidden, Near 1K, and Graduated views
Repo cards	Stars, momentum, status, category, save actions, and direct GitHub links
Detail drawer	Longer context, README preview, related repos, and next/previous browsing
Profile	Private Watchlist and Collections for signed-in users
Data	Dataset health, validation status, source files, fastest risers, and archives
Submit	Protected intake for repos that should be reviewed

Current Snapshot

active repos: 1000
active under 1K: 1000
archive repos: 193
risen repos: 32
duplicate ids: 0

Quick Start

npm install
npm run dev

Useful checks:

npm run build
npm run lint
npm run validate:data

Discovery Statuses

Status	Meaning
Underrated	Still under 1,000 stars
Rising	Growing quickly or showing strong momentum
Near 1K	Close to crossing the 1,000-star threshold
Crossed 1K	Graduated from underrated
Archived/Inactive	Unavailable, archived, disabled, or stale

Data Protection

The active dataset lives at:

public/data/all_repos.json

Archive shelves live at:

public/data/archive_repos.json
public/data/risen_repos.json

The app protects this file as the source of truth:

• raw repo data is not rewritten by the public UI,
• submissions do not directly mutate the dataset,
• accepted submissions go through a reviewer command,
• daily GitHub refreshes open PRs for review,
• validation checks repo count, required fields, and duplicate ids.

Accounts and Collections

UND-RDR has live GitHub sign-in through Supabase Auth. Signed-in users can save repos to a private Watchlist and create named Collections from the Profile workspace. The account tables use row-level security, so each user can only read and manage their own saved repos.

The public dataset is still static and protected. Account actions never mutate public/data/all_repos.json.

Implementation notes:

src/lib/accountStorage.ts
docs/supabase-auth-collections.md

Submission Workflow

Public submissions go through the live endpoint:

/api/submit-repo

The endpoint:

• accepts full GitHub repo URLs,
• blocks invalid URLs,
• blocks repos already in the dataset,
• blocks repos already waiting in an open review issue,
• creates a GitHub issue labeled undrdr-submission and needs-review,
• never changes the live dataset directly.

Public contact is submit@undrdr.com. DNS and mailbox readiness are tracked in:

docs/email-intake.md

Reviewer guide:

SUBMISSIONS.md

Preview an accepted issue:

npm run submissions:add -- --issue 12 --dry-run

Apply an accepted issue:

npm run submissions:add -- --issue 12

The script fetches GitHub metadata, refuses duplicates, writes a backup, appends one normalized repo record, validates data, comments on the issue, labels it accepted plus added-to-index, and closes the issue.

Mark a submission that needs more information:

npm run submissions:review -- --issue 12 --outcome needs-data --comment "Need more signal before accepting."

Close a duplicate or rejected submission:

npm run submissions:review -- --issue 12 --outcome duplicate --comment "Already tracked or already pending."
npm run submissions:review -- --issue 12 --outcome rejected --comment "Not a fit for UND-RDR right now."

Curator Candidate Workflow

For owner-curated additions, paste GitHub links into:

data/repo-candidates.txt

Preview candidates:

npm run candidates:check

Add valid new candidates:

npm run candidates:add

The candidate workflow fetches live GitHub metadata, skips duplicates, writes a backup, appends only new repos, and runs validation. Details are in:

docs/repo-candidates.md

Recent curated batches:

data/under-the-radar-github-repos-100-20260524.txt
data/next-100-ai-tooling-candidates-20260521.txt

The May 24 CSV batch was parsed from /Users/kika_hub/Downloads/under_the_radar_github_repos_100.csv. The importer checked 100 repos, added 91 new candidates, skipped 9 already tracked repos, and later shelf rotation restored the active public dataset to the 1,000-repo cap.

The May 21 batch added 100 under-the-radar AI tooling repos, moving the protected dataset from 913 to 1,013 repos.

The private browser Curator page at /#/curator is protected by the production CURATOR_ACCESS_TOKEN environment variable. It is for owner batch intake only and still creates review issues instead of editing the live dataset directly.

Daily Automation

The GitHub Actions workflow at:

.github/workflows/github-repo-check.yml

runs daily and can also be triggered manually. It checks all repos, updates stars/status signals, validates the dataset, and opens an update PR from:

automation/github-repo-snapshot

It does not push dataset changes directly to main.

Each update PR includes a review summary with new 1K graduates, near-1K repos, fastest risers, and unavailable or failed GitHub checks. Pre-update backups are uploaded as short-lived workflow artifacts, while only the dataset and public report are committed.

Local Development

Install dependencies:

npm install

Run the app:

npm run dev

Build:

npm run build

Validate the dataset:

npm run validate:data

Run a sample GitHub metadata check:

npm run check:github:sample

Run the full GitHub metadata check locally as a dry run:

npm run check:github

Apply a full local GitHub metadata refresh:

npm run check:github:apply

Domain

UND-RDR is live at:

https://undrdr.com

The project previously lived under akaKika.com/undrdr. Keep legacy redirects alive while search, social previews, and external links settle.

SEO and GEO

UND-RDR exposes human and AI-readable discovery surfaces:

• index.html includes canonical metadata, Open Graph/Twitter cards, WebSite/WebApplication/Dataset/FAQ JSON-LD, and links to AI summary files.
• public/llms.txt gives answer engines a direct summary, dataset snapshot, categories, FAQ, and citation wording.
• public/ai-summary.json provides a structured machine-readable summary of the entity, dataset, categories, features, and trust signals.
• public/sitemap.xml points to the site, AI summary files, and public data endpoints.
• src/main.tsx loads Google Analytics only when VITE_GA_MEASUREMENT_ID is configured.

Tech Stack

• React
• TypeScript
• Vite
• Pixi.js
• Vercel
• Supabase Auth and Postgres
• GitHub Actions

Product Direction

UND-RDR should feel like a curated discovery system: clean, fast, editorial, data-first, and useful. It should help people move from one interesting GitHub project to the next without overwhelming them.
