Features and specs

What each product offers, as listed by its team.

Stillindexed 17 features
Modular JavaScript 5 features
  • Indexability monitoring
    Meta robots, X-Robots-Tag header and robots. txt evaluated per URL, so a noindex is caught whether it is in the HTML or a response header.
  • 15 or 30 minute check cadence per monitored URL (Agency / Starter)
    Site-level checks (robots.txt, sitemap, TLS) daily; domain expiry weekly.
  • Canonical and redirect monitoring
    Canonical target, HTTP status, and the full redirect chain, hop by hop.
  • Sitemap health
    Reachable, valid XML, URL count; sitemap index expansion.
  • Certificate Warnings
    SSL certificate and domain expiry warnings via TLS and RDAP.
  • False-positive suppression
    Critical change is confirmed by a second fetch before it alerts; flapping is held back.
  • Alerts by Telegram, Email and Slack
    Stating what changed, where, when, and the before/after. One incident, one alert, one resolved notice.
  • Weekly report per site
    Weekly "we watched, nothing broke" report per site; white-label on Agency so it can be forwarded to a client unedited.
  • Coverage shown
    Checks attempted vs pages actually loaded, per site, per week.
  • No site access needed
    Public URLs only. No Google account, no snippet, no credentials.
  • Bulk URL import
    Paste the list your audit produced; every line gets a decision, nothing is dropped silently.
  • Published crawler identity
    Fixed user agent and allowlisting guide at /bot.
  • Public canary
    A page that breaks itself every four hours and a live log of every check and alert, with measured detection latency.
  • Free checkers
    Indexability, X-Robots-Tag, robots. txt, canonical, redirects, sitemap, title/meta, H1, SSL and domain expiry, bulk (20 URLs), crawler-vs-browser diff.
  • MCP server
    The same checkers callable from Claude Code, Cursor, Codex or any MCP client, no key.
  • SEO skill generator
    SKILL.md for any host with its expected state, platform traps and a re-check runbook.
  • Migration Watch (Agency)
    14-day window with 5-minute cadence and a daily digest around a site migration.
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

  • Covers practical patterns for organizing code, managing dependencies, and structuring larger applications
  • Can help bridge the gap between basic JavaScript knowledge and professional-grade architecture skills
  • Often includes real-world examples rather than purely theoretical concepts
  • Useful for understanding module systems like CommonJS, ES Modules, and build tool configurations

Recommended for

  • Intermediate JavaScript developers wanting to level up their code organization skills
  • Developers transitioning from simple scripts to larger, maintainable applications
  • Teams looking to establish consistent modular coding standards
  • Self-taught programmers seeking structured guidance on architecture
  • Backend or frontend developers working with Node.js or modern JS frameworks who need better module management practices

Questions & Answers

As answered by people managing Stillindexed and Modular JavaScript.

What makes your product unique?

Stillindexed's answer

It publishes its own evidence instead of adjectives. A public canary page breaks itself on a fixed schedule every four hours, and the log at api.stillindexed.com/canary/log shows every check and alert with the measured detection latency (median 16 minutes to detect, 18 to alert, on the slower plan). The crawler's identity and limits are published at /bot. Every check reads what the server actually returned, meta robots, X-Robots-Tag headers, robots.txt, canonicals, redirect chains, so a noindex in a response header is caught, not just one in the HTML. Pricing is public, there is no sales call, and no site access is required.

Why should a person choose your product over its competitors?

Stillindexed's answer

Because it interprets a URL's indexability automatically at a self-serve price. Generic change monitors (Visualping, Hexowatch, changedetection.io) diff whatever selector you configure and leave you to decide what the change means. Audit suites (Screaming Frog, Sitebulb, Ahrefs, Semrush) crawl on a schedule you read later. The SEO-aware monitors that do interpret changes start at $199 a month (SEORadar) or hide pricing behind a sales process (Conductor Monitoring). Stillindexed checks every 15 or 30 minutes, confirms a critical change with a second fetch before alerting, sends the before/after to Telegram and email, and starts at $39 a month for 15 sites. When Little Warden or Oh Dear fits better, the comparison pages on the site say so.

How would you describe the primary audience of your product?

Stillindexed's answer

Freelance technical SEO consultants and agencies of two to ten people who manage 5 to 50 client sites on retainer, especially around site migrations. Their problem is finding out about a broken noindex, robots.txt or canonical from the client three days late. It is not built for enterprises, in-house teams at large companies, or developers who want uptime or cron monitoring.

What's the story behind your product?

Stillindexed's answer

An accidental noindex or robots.txt block typically sits live for 24 to 72 hours before anyone notices. Search Console reports it after the indexing damage, and its reports are often days behind. Recovery takes one to three weeks after the fix, and for an agency the cost is the client relationship. Existing tools were either enterprise crawlers with sales-led pricing, or generic page-diff monitors with no SEO semantics. Stillindexed was built as the narrow thing in between: plain HTTP fetches of the directives Google's indexing decision trusts first, on a short cycle, with an alert that names the change. It was built by one person and is designed to stay maintainable by one person, which is why it does one job and publishes its own proof.

Which are the primary technologies used for building your product?

Stillindexed's answer

Go (stdlib net/http) for the API and the checker worker, PostgreSQL 17 with River for job scheduling, Astro for the marketing site, Vite and React with TypeScript for the app, plain CSS, Docker Compose behind Traefik, Polar for billing, Telegram and email for alerts.
