About StackBlitz and Klaxel

In their own words, as submitted to SaaSHub.

StackBlitz
Klaxel

No description of StackBlitz yet.

Klaxel is domain-health monitoring built for agencies and MSPs. Registrars email renewal notices to your client's inbox, not yours — so a silently expired domain (or a lapsed TLS cert, or a broken DMARC record) takes a client site dark and you take the blame. Klaxel watches every domain you...

Features and specs

What each product offers, as listed by its team.

StackBlitz 6 features
Klaxel 13 features
  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.
  • Domain expiry monitoring
    Registrars remind the client; we remind the agency. Daily RDAP checks, escalating alerts at 60 / 30 / 14 / 7 / 1 days and the moment a domain lapses.
  • A–F health grade
    Every domain graded A–F across 14 automated checks, so you triage the whole client fleet at a glance.
  • TLS / SSL certificate monitoring
    Certificate expiry plus configuration posture — alerts before a cert lapses or weakens.
  • DNS & DNSSEC checks
    Nameserver resolution and DNSSEC validation on every domain.
  • Email authentication
    SPF, DKIM, DMARC and MX checked continuously — catch deliverability breakage before clients do.
  • Web security checks
    HTTPS enforcement, HSTS, redirect chains, and subdomain-takeover exposure.
  • Indexability & reputation
    robots / sitemap sanity plus IP blocklist (RBL) reputation checks.
  • Brand / typosquat watch
    Detects lookalike and typosquat domains registered against your clients' brands.
  • White-label reporting
    Per-client branding and branded monthly PDF reports under your agency's identity.
  • Alert routing
    Route alerts to email, Slack, Microsoft Teams, webhooks, or a PSA ticket.
  • PSA ticketing (ConnectWise)
    Auto-open and update ConnectWise tickets mapped to the right client; repeats dedupe into notes (idempotency-keyed, no duplicates).
  • Multi-client fleet management
    Client groups and per-domain settings — one dashboard across every registrar.
  • Free single-domain checker
    Instant, no-signup domain health check at klaxel.com/check

Questions & Answers

As answered by people managing StackBlitz and Klaxel.

What makes your product unique?

Klaxel's answer:

It reads each domain's expiry straight from the registry's official RDAP record — the structured, machine-readable successor to WHOIS — so the date is authoritative, not scraped or guessed. And it alerts you, the agency or MSP, across every client and every registrar in one place. That's the core insight: registrars send the renewal reminder to the domain owner's inbox (your client), which is exactly why domains silently lapse on your watch. Klaxel is the reminder that actually reaches the person responsible — escalating warnings at 60, 30, 14, 7, and 1 day out, plus an alert the moment one expires. The same watch extends to TLS certificates, DNS/DNSSEC, email authentication (SPF/DKIM/DMARC) and web security — every domain graded A–F.

Why should a person choose your product over its competitors?

Klaxel's answer:

Registrar reminders only cover their own domains and only notify the owner. Uptime/SSL monitors tell you a site is already down — too late to renew. Klaxel is purpose-built for the agency or MSP managing many clients' domains across many registrars: one list, daily RDAP-verified checks, and escalating alerts that reach you before anything lapses — backed by a full A–F health grade (TLS, DNS, email auth, web security) and white-label reports you can hand straight to clients. Paste your domains once; the alerts come to you — no per-registrar logins, no spreadsheet. From $99/mo for 100 domains (Core MSP 500, Enterprise 2,000).

How would you describe the primary audience of your product?

Klaxel's answer:

MSPs, web agencies, freelancers, and design/dev studios that manage domains on behalf of clients — the people who look responsible (and lose the site) when a client's domain quietly expires, even though the renewal was never theirs. Also small in-house teams juggling a portfolio of domains spread across multiple registrars.

What's the story behind your product?

Klaxel's answer:

It was built around a painfully common failure mode: an agency loses a client's site because the domain expired — the registrar's reminder went to the client (whose payment card had since expired), and the agency only found out when the site went dark and the client called. Registrars remind the owner; nobody reminds the agency. Klaxel exists to be the agent that does — watching every client domain, across every registrar, and warning the agency or MSP before it's too late.

Which are the primary technologies used for building your product?

Klaxel's answer:

  • Next.js (React) + TypeScript, Tailwind CSS
  • Prisma ORM + PostgreSQL
  • AWS — App Runner (hosting), RDS, SES (email alerts)
  • Stripe (billing)
  • The IANA RDAP protocol for authoritative registry expiry data
