# StackScope

> Tech stack intelligence for new product launches.

StackScope is an independent directory of new product launches, annotated with the tech behind them. Most of what we index we find ourselves: a first-party discovery pipeline locates new sites from public infrastructure signals, without waiting for anyone to post them. We also take publicly-posted launches from Product Hunt, Hacker News, and PeerPush. Every site is analysed on its public surface, and we publish what it is built with. Every detection comes from content a regular browser can see. No logins, no forms, no authenticated access.

## Pages

- [Homepage](https://stackscope.dev/): search and latest launches
- [Browse launches](https://stackscope.dev/browse): every launch we have analysed, each with its own detail page
- [Technology directory](https://stackscope.dev/tech): all technologies we track, each with a page listing the sites using it
- [Category directory](https://stackscope.dev/category): technologies grouped by product type
- [Hosting directory](https://stackscope.dev/hosting): launches by hosting provider
- [Technology trends](https://stackscope.dev/trends): what is rising and falling this month
- [Corpus insights](https://stackscope.dev/insights): stats across the whole corpus
- [Indie starter pack](https://stackscope.dev/starter-pack): shareable card of the most common indie stack
- [Most-blocked bots](https://stackscope.dev/most-wanted): which crawlers new sites block
- [Launch directories](https://stackscope.dev/launch-directories): where to submit a new product, with a profile per directory
- [Common stacks](https://stackscope.dev/stacks): technologies that appear together
- [Data, API and pricing](https://stackscope.dev/data): what is in the dataset, what the paid API covers, and what it costs
- [Scoring methodology](https://stackscope.dev/methodology): how the scores are calculated
- [About StackScope](https://stackscope.dev/about): who runs it and why
- [About our crawler](https://stackscope.dev/bot): StackScopeBot details and opt-out

- [XML sitemap](https://stackscope.dev/sitemap.xml): machine-readable page index

## What we publish

Each launch page lists the technologies detected on that site, covering areas like frameworks, hosting, CDNs, DNS, analytics, and email infrastructure, alongside these scores:

- StackScope Score (0-10): headline composite across security headers, launch readiness, legal pages, and web standards
- Vibe Score (0-100): an informational count of AI-assisted-build patterns; it does not feed the StackScope Score
- Launch Readiness (0-100): basic launch-day hygiene
- Security Headers (0-6): count of recommended security headers present

Technology detection and all scoring are performed by deterministic, auditable code: a fingerprint rule matches an observed value, or it does not. No model decides what a site is built with, and no score is model-derived.

Two things are classified by self-hosted machine-learning models rather than rules: the product category shown on a launch page, and the internal triage decision about whether a discovered site is an indie launch. Both run on our own hardware. No launch data is sent to a third-party AI service.

## Paid services

Alongside the free directory, StackScope sells access to the underlying data:

- A read API over the corpus, filterable by technology, category, country, launch type and date range
- Spreadsheet exports of the same queries
- Stackdar, which watches chosen technologies and reports what changed

Product Hunt data is excluded from every paid service. A site Product Hunt listed is served only where our own discovery pipeline found it independently, and never with Product Hunt's name, tagline or link attached.

Coverage, limits and pricing are at [stackscope.dev/data](https://stackscope.dev/data).

## Crawler

Our crawler identifies itself as `Mozilla/5.0 (compatible; StackScopeBot/1.0; +https://stackscope.dev/bot)`. It respects robots.txt, crawls each launch once, may occasionally re-crawl to apply a bug fix or schema change, and never submits forms, clicks buttons, or accesses authenticated areas. Full details and opt-out instructions are at [stackscope.dev/bot](https://stackscope.dev/bot).

## Data sources

Most sites come from our own first-party discovery pipeline, which finds new domains from public infrastructure signals without waiting for anyone to post them. That stream is the majority of what we index and is not limited to startup launches: much of it is the ordinary new web, and every record carries a flag saying which it is.

The rest are publicly-posted launches from Product Hunt daily launches, Hacker News Show HN posts, and PeerPush recent launches, via their public APIs. Sites on major platforms and marketplace listings are filtered out.
