Joel Griffith - Browserless

[hipstersmoothie]

Joel Griffith is the founder and CEO of Browserless, a service that provides headless browser automation without the pains of infrastructure management. A former professional jazz trumpet player turned engineer, Joel built Browserless after experiencing firsthand the challenges of running headless Chrome in production environments. The company has grown to $1.3M in annual revenue with 3,000+ customers, all while remaining bootstrapped.

Questions

Background & Origin Story

• You have one of the more unique origin stories in tech—you started as a professional jazz trumpet player. What was that transition like, and what drove you to make such a dramatic career change?

  Joel spent over a decade as a professional trumpet player before transitioning to tech. He's mentioned that "life tragedies" and having kids prompted the career change when a musician's salary wasn't going to cut it. This creative background is something he believes many engineers share and contributes to problem-solving abilities.

• The story of how Browserless started is fascinating—you were building a project when you ran into a problem that sparked the idea. Can you walk us through that "aha moment"?

  Joel was building a wishlist site that needed to scrape retail pricing data. When he encountered Target's SPA that returned no usable HTML initially, he realized he needed to run a browser to parse and execute JavaScript. After discovering no good solutions existed, he pivoted entirely and started Browserless.

The Problem Space & Technical Challenges

• For developers who haven't dealt with headless browsers at scale, what are the actual pain points you're solving? Why is this so hard to do yourself?

  Chrome binds to random ports and interfaces, requires complex CLI tooling, has security vulnerabilities, memory leaks, and version management issues. Joel describes it as "the missing management layer for headless Chrome" - handling dependencies, sandboxing, and infrastructure that teams shouldn't have to build themselves.

• You've written extensively about memory leaks in headless browsers—what makes Chrome so prone to these issues, and how did you solve them?

  Joel has blogged about "Hunting White Whales: JavaScript Memory leaks" and the specific challenges of running Chrome at scale. Browserless implements queuing, concurrency limitations, and process isolation to manage Chrome's notorious memory consumption.

• What are the most common use cases you see at scale? What are some that surprised you?

  Major use cases include: (1) Load testing—since most load testing tools don't execute JavaScript but everyone's building SPAs, (2) Web scraping, (3) PDF/screenshot generation, (4) AI agents and LLM data ingestion, (5) E2E testing. The AI use case has become significant with the "AI gold rush."

• The cat-and-mouse game between scrapers and bot detection is fascinating. How do you stay ahead of services like Cloudflare and Datadome?

  Joel describes it as an "arms race" where the ante keeps getting raised. Their approach includes minimal fingerprints, premium hardware, residential proxies, CAPTCHA solving within nested iframes, and session persistence to avoid repeated bot checks. The key insight is building a specialized tool rather than cobbling together stealth plugins.

• The ethics of web scraping exist on a spectrum. How do you think about the legitimate vs. illegitimate uses of your service?

  Joel acknowledges it's "never black and white"—web scraping is "the skeleton in everyone's closet." He points to legitimate uses like government bodies checking for scam shopping sites, but notes those same bodies run into the same bot-detection problems. Every corporation he's worked at has had scraping "at some level in their stack."

BrowserQL & Technical Innovation

• BrowserQL is your next-gen scraping and automation tool with its own query language. What problems were you trying to solve that Puppeteer and Playwright couldn't?

  BrowserQL was built from the ground up to avoid leaving automation fingerprints that bot detection services catch. Unlike Puppeteer/Playwright which leave traces "all over the place," BrowserQL is designed for stealth—auto-humanized clicking, scrolling, and typing, plus the ability to click verify buttons hidden in iframes and shadow DOMs.

• You rebuilt Browserless 2.0 from the ground up—400 days of developer time. What drove that decision and what were the biggest technical changes?

  The rebuild focused on reducing dependency on npm/JavaScript packages and building custom components. Joel has emphasized the importance of tackling tech debt while being strategic about timing—he deliberately avoided migration to Kubernetes mid-launch because "time and revenue were more important than developer-ergonomics."

Open Source & Business Model

• You've navigated the tricky balance of open source with commercial sustainability. Walk us through your licensing journey and philosophy on charging for software.

  Joel is "very biased towards not taking funding" and strongly advocates for charging for software rather than relying on sponsorships. He started with GPL-3 to signal commercial use requires a license, later moved to the MongoDB Server Side Public License. His key insight: "It's better to start more constrictive with a license and then get more permissive over time."

• You've been vocal about sponsorship models rubbing you the wrong way. Can you expand on why you think developers should "just charge" for their software?

  Joel believes sponsorship signals uncertainty: "Anytime I hear that, I just feel like it's pre-beta or alpha...if it was [worth something], why aren't they just charging money for it?" He argues this model undervalues what developers create and fails to communicate confidence in the product's value.

• You've written about "things they don't teach you running a business by yourself." What was the hardest lesson?

  Key lessons include: leverage time and tech-debt strategically, set artificial deadlines to avoid analysis-paralysis, don't risk launching for non-essential improvements, and hold onto "small wins" (like seeing Codepen sign up) when searching through logs at 2AM. He also emphasizes that the growth shown by successful indie businesses is often an "outlier."

AI Integration & The Future

• AI is "a big one right now" for Browserless. How are you seeing AI agents and LLMs use headless browsers, and what does that integration look like?

  Browserless integrates with LangChain as a document loader, Vercel AI SDK, and Browser-Use for agentic browsing. The key use case is providing LLMs with real web data—the BrowserlessLoader returns page content that can be processed by long-context models like GPT-4 or Claude for field extraction, content classification, and more.

• You mentioned "access to data" being almost like a human right. Can you expand on that philosophy?

  Joel sees the bot-detection arms race as working against open access to information. He draws a parallel to access to clean water—data access should be fundamental, but the current ecosystem of bot blocking works against that principle. Though he acknowledges it's "incredibly nuanced."
