About ServiceGraph and Opalstack

In their own words, as submitted to SaaSHub.

ServiceGraph
Opalstack

ServiceGraph is datasets for founders — where to launch, who to email, who to hire. Every founder ships a product and hits the same wall: where do I actually launch this, who do I email to grow, who do I hire? The honest answers are scattered — in 2-year-old listicles where half the links 404, in...

Possible disadvantages

  • Smaller Community and Ecosystem
    Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
  • Limited Scalability Options
    Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
  • Not Ideal for Beginners
    While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
  • Limited Data Center Locations
    Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
  • Fewer Managed Services and Add-ons
    Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.

Overall verdict

  • I don't have verified, specific information about a product called 'ServiceGraph' at servicegraph.co, so I can't confirm whether it's good or provide an accurate assessment.

Why this product is good

  • I don't have reliable, up-to-date data on this specific website or product to evaluate its merits
  • Providing a confident verdict without verified information could mislead you
  • Company websites and products can change frequently, so even if I had prior knowledge it may be outdated

Recommended for

  • Anyone considering this service should check recent user reviews on independent platforms
  • Visit the actual website to review their current offerings, pricing, and customer testimonials
  • Look for third-party reviews on sites like G2, Trustpilot, or Capterra if it's a business software product
  • Reach out to their support team directly with specific questions about your use case

Overall verdict

  • Opalstack is a solid choice for developers and tech-savvy users seeking an affordable, flexible control panel hosting solution with good performance and transparent pricing, though it may require more technical know-how than mainstream cPanel hosts.

  • Offers straightforward, transparent pricing without hidden fees or aggressive upselling
  • Provides SSD storage and solid server performance for the price point
  • Supports multiple app types including Python, Node.js, and various frameworks beyond typical PHP hosting
  • Founded by the original creators of WebFaction, bringing significant hosting industry experience
  • Good for running multiple websites/apps under one account with granular resource control
  • Responsive customer support with a knowledgeable team
  • No long-term contracts required, allowing flexibility

Questions & Answers

As answered by people managing ServiceGraph and Opalstack.

What makes your product unique?

ServiceGraph's answer

Most "where to launch / who to email / who to hire" lists online are stale — 2-year-old listicles where half the links 404, ChatGPT answers that invent URLs, frozen Notion lists nobody updates. ServiceGraph is the live alternative: curated datasets of product directories, business directories, newsletters and agencies, each row carrying real metrics — traffic, domain rank, subscriber counts, ratings — refreshed continuously and exportable as CSV or JSON.

Why should a person choose your product over its competitors?

ServiceGraph's answer

Three reasons. (1) Freshness — most directory aggregators publish once and rot; we maintain ours as a living dataset. (2) Real metrics on every row, not just a list of names — filter directories by DR and traffic for SEO, newsletters by subscriber count for outreach, agencies by ratings and location for hiring. (3) Zero-friction trial — browse, search and filter completely free; 2,000 credits on signup, no card, credits don't expire.

How would you describe the primary audience of your product?

ServiceGraph's answer

Founders and growth operators at early-stage startups, typically 1–10 people, who just shipped a product or are about to. They keep hitting the same three questions: where do I launch this, who do I email to grow, who do I hire. Solo indie hackers, small SaaS teams, and the marketers and agencies who serve them.

What's the story behind your product?

ServiceGraph's answer

We built it for ourselves. Every time we shipped, finding the right places to launch and the right people to reach ate a full day of googling stale listicles and asking ChatGPT for URLs that didn't exist. We started maintaining our own list — with real traffic and domain-rank attached to each row — and realized every other founder was hitting the same wall. So we turned the internal tool into a product. Operated by NostrCorp, Inc. (Delaware).

Which are the primary technologies used for building your product?

ServiceGraph's answer

TypeScript on the application side (web app and product API). Python for the data and ML pipeline that enriches and classifies rows across all datasets — directories, newsletters, agencies. ClickHouse as the storage and analytics backbone — chosen for fast aggregations across millions of rows so search, sort and filter stay snappy even on the 110k+ agencies dataset. REST API over HTTP exposed at docs.servicegraph.co.
