Features and specs

What each product offers, as listed by its team.

Node.js 6 features
PermitGrab 9 features
  • Asynchronous and Event-Driven
    Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
  • JavaScript Everywhere
    Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
  • Large Community and NPM
    Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
  • High Performance
    Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
  • Scalability
    Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
  • JSON Support
    Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages

  • Callback Hell
    The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
  • Not Suitable for CPU-Intensive Tasks
    Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
  • Immaturity of Tools
    Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
  • Callback and Promise Overheads
    Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
  • Fragmented Ecosystem
    The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
  • Security Issues
    The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.
  • Daily permit digest
    One ranked email each morning with the day’s new filings for your cities
  • Coverage
    800+ US cities across all 50 states, refreshed daily
  • Data sources
    Official municipal and county open data (ArcGIS, Socrata, CKAN, Accela, Tyler EnerGov)
  • Contractor contacts
    Business name and phone number attached where a match exists
  • Code violations
    Open enforcement cases tied to property and owner
  • Property-owner records
    Owner name, mailing address and phone where available
  • Filtering
    By city, trade, project value, permit type and date
  • CSV export
    CRM-ready export of any filtered view
  • Lead exclusivity
    Not resold — no bidding against other contractors for the same job

Questions & Answers

As answered by people managing Node.js and PermitGrab.

What's the story behind your product?

PermitGrab's answer:

Building permits are public record everywhere in the United States. Anyone can go and read them. In practice almost nobody does, because there is no such thing as 'the permit database' - there are hundreds of separate municipal and county systems, each on different software, each with a different schema, and most with no way to ask the only question a contractor actually cares about: what is new since yesterday?

So the information sits there, free and public, and the contractor who could use it finds out about the job weeks later, if at all.

PermitGrab exists to close that gap. The hard part was never getting a permit record. It was doing it every day, across hundreds of jurisdictions that change their endpoints without warning, and turning inconsistent municipal records into something a roofer can act on before breakfast.

What makes your product unique?

PermitGrab's answer:

PermitGrab combines three public records that are normally sold separately, or not sold at all: building permits, code-enforcement violations, and property-owner contacts. Most permit tools stop at the permit. Pairing a filing with the violation history on that property and the owner of record is what turns an address into a conversation.

The other difference is the delivery model. It is one ranked email each morning rather than a dashboard you have to remember to check, and it is a flat monthly rate rather than per-lead pricing. Leads are not resold, so you are not calling a homeowner who just heard from seven other contractors.

Why should a person choose your product over its competitors?

PermitGrab's answer:

It depends what you are comparing against.

Against lead-generation marketplaces such as Thumbtack, HomeAdvisor or Angi: those sell you a shared lead that several contractors receive at once, priced per lead. PermitGrab is a flat monthly rate and the records are not resold, because they are public filings rather than a homeowner form submission. You are reaching out first instead of competing on response time.

Against construction data platforms such as BuildZoom, Shovels or ConstructConnect: those are generally built for enterprise research, analytics or commercial project intelligence, and are priced accordingly. PermitGrab is aimed at the individual contractor who wants to know what got filed in their city this morning, and it adds code violations and property-owner contacts alongside the permit rather than the permit alone.

Against checking the county portal yourself: the data is genuinely free and public. The work is that it is spread across hundreds of separate municipal systems with different formats, and none of them tell you what changed today.

How would you describe the primary audience of your product?

PermitGrab's answer:

Small and mid-sized contractors who sell into residential and light commercial work, and who do their own prospecting.

The clearest fits are roofing, HVAC, plumbing, electrical, general contracting, remodeling, restoration, solar, fencing, concrete and landscaping. A new-construction permit means every one of those trades has work coming. A re-roof permit means a solar installer has a fresh roof to quote.

It also works for building-material suppliers and manufacturer reps who want to know which builders are active in a territory, and for investors and agents who use code-enforcement records to find owners with a reason to sell.

It is a poor fit for anyone who needs national enterprise coverage with an SLA, or who wants commercial project intelligence at the pre-bid stage. That is a different product category.

Which are the primary technologies used for building your product?

PermitGrab's answer:

  • Python and Flask for the application and the collection daemons
  • PostgreSQL for the permit, violation, contractor and property-owner records
  • Render for hosting, split across a web service and a background worker
  • Stripe for billing and Resend for the daily digest delivery

On the ingestion side the work is mostly adapters rather than a single framework. Municipal data arrives through ArcGIS FeatureServer and MapServer endpoints, Socrata, CKAN, Accela ACA portals, Tyler EnerGov self-service, OpenGov and a handful of one-off formats, so each source gets its own field mapping and freshness check.
