RB2B Alternative for DevTool Companies — Why GitHub Signals Beat Website Deanonymization
By Sam Petrenko, Founder · Published June 2026 · 8 min read
TL;DR
- RB2B is good at what it does — person-level deanonymization of US website visitors. For most B2B companies, that’s useful.
- For DevTool companies, it catches a fraction of actual evaluators. Developers research tools on GitHub, in docs, in Discord — not primarily on your marketing site.
- LeadCognition tracks GitHub stars, forks, contributor activity, and competitor repo engagement — signals RB2B structurally cannot see.
- The right setup is both: RB2B for website visitors, LeadCognition for GitHub signals. Full-funnel coverage, no overlap.
What RB2B Does Well
RB2B solves a real problem. You’re spending on SEO, paid search, and content. People land on your site. You have no idea who they are. RB2B resolves those anonymous sessions to real people — name, LinkedIn profile, company — and pushes them to Slack in real time.
It works. For a US-focused B2B SaaS selling to buyers who browse vendor websites before purchasing, RB2B gives your SDR team a meaningful list of warm leads to work. The product is fast to set up, the Slack integration is clean, and the free tier gets you started without commitment.
That’s the honest case for it. The rest of this post is about where it falls short for DevTool GTM specifically — and why that gap matters more than people realize.
The Problem With Website-Only Signals for DevTools
Here’s the structural issue: developers don’t evaluate developer tools the way enterprise buyers evaluate software.
An enterprise buyer researching a new security vendor might visit the vendor’s website, read the case studies, download a white paper, and request a demo. That entire journey is trackable via website analytics and visitor identification tools like RB2B.
A developer evaluating a new observability library does this instead:
- Finds it mentioned in a GitHub issue thread or Discord server
- Checks the GitHub repo — README, star count, recent commit activity, open issues
- Looks at the CHANGELOG and open PRs to gauge maintenance health
- Forks it or clones it locally to test
- Maybe visits your docs site
- Possibly (but not always) lands on your marketing website
That marketing website visit is step six of a six-step process that started on GitHub. You’re identifying the evaluator at the very end of their research — if at all. And for a large share of your evaluators, step six never happens. They evaluate entirely on GitHub and go directly to a free trial or self-serve signup.
The numbers back this up. DevTool companies with active open-source repos consistently see 5–10x more GitHub activity (stars, forks, clones) than unique website visitors in a given period. If you’re only tracking website visitors, you’re looking at 10–20% of your actual evaluator universe.
What GitHub Signals Catch That RB2B Misses
GitHub intent data surfaces a category of signal that website tracking structurally cannot reach:
Stars from developers who never visited your site. When a developer stars your repo, they’re expressing genuine interest — often stronger than a website visit, because they had to find your repo through a non-marketing channel. LeadCognition resolves the GitHub user to a company and enriches the identity with org, team size, and tech stack context.
Companies whose engineers forked your library. A fork is higher intent than a star. It means someone is actively exploring integration or customization. Fork activity often comes from engineering teams at companies you’d never reach through paid acquisition or website traffic.
Contributors to competing repos. Developers who are actively contributing to a competitor’s open-source project are your highest-value prospecting universe — they have deep context on the problem space and are already invested in solutions like yours. You can surface these from developer buying signals without ever waiting for them to visit your marketing site.
Issue openers and commenters. Developers who open issues on your repo are expressing hands-on evaluation. Developers who comment in issues on competitor repos may be signaling frustration or interest in alternatives. Both are actionable signals RB2B has no visibility into.
RB2B vs LeadCognition — Side-by-Side
| RB2B | LeadCognition | |
|---|---|---|
| Signal source | Marketing website visits | GitHub stars, forks, PRs, issues, competitor repos |
| Identity resolution | Person-level (US only) | GitHub user → company, team, tech stack |
| Developer-specific signals | No | Yes — built for DevTool GTM |
| Coverage geography | US visitors only | Global (GitHub is global) |
| Self-serve setup | Yes | Yes |
| Free tier | Yes (limited) | Yes — up to X repos monitored |
| Paid pricing | From ~$119/mo | From $99/mo |
| CRM/Slack integration | Yes | Yes |
| API access | Limited | Full API + DataForGTM for pipelines |
The key difference isn’t features — it’s signal source. RB2B can only tell you about people who visited your website. LeadCognition tells you about developers who engaged with your code, your category, or your competitors’ code on GitHub — regardless of whether they ever hit your domain.
Use Both: They’re Complementary, Not Competing
The framing of “RB2B alternative” undersells what’s actually worth doing. You shouldn’t replace one with the other. You should run both.
Here’s the combined signal picture:
- RB2B catches: developers who visited your pricing page, documentation site, or blog after finding you through search or an ad
- LeadCognition catches: developers who starred your repo, forked your library, opened an issue, or engaged with a competing repo — most of whom never visited your website
Together, you get something close to full-funnel developer intent coverage. RB2B fills the bottom of the funnel (high-intent website visitors). LeadCognition fills the top and middle (early-stage GitHub evaluators who haven’t entered your marketing funnel yet).
The operational play is simple: route RB2B alerts to your SDR team for immediate follow-up, and route LeadCognition GitHub signals to a nurture sequence or a lighter-touch outreach motion — since these developers are earlier in evaluation and need a warmer approach than “you visited our pricing page.”
For Agent-Driven GTM Pipelines
If your team is building automated GTM pipelines — combining multiple signal sources, enriching accounts, scoring intent, and triggering sequences without manual intervention — DataForGTM is worth knowing about.
DataForGTM is the API layer for exactly this use case. It exposes GitHub signal resolution as a pay-per-resolve API with MCP (Model Context Protocol) support, which means you can wire it into Claude-based agents, n8n workflows, or custom tooling alongside RB2B’s data. Instead of manually exporting from two tools and reconciling in a spreadsheet, you build a pipeline that ingests signals from both sources, deduplicates at the company level, scores by intent, and routes to the right sequence automatically.
It’s particularly useful when you want to run both website visitor signals and GitHub signals through a unified scoring model — rather than treating them as separate, disconnected lists.
FAQ
Is RB2B free?
RB2B has a free tier that gives you a limited number of person-level identifications per month. Paid plans start at approximately $119/month for higher volumes and additional features. Pricing has varied — check their current site for up-to-date tiers.
Does RB2B track GitHub activity?
No. RB2B identifies visitors to your website by resolving anonymous sessions to real people using IP matching and identity graph data. It has no visibility into activity on GitHub, npm, Docker Hub, or any third-party platform. If a developer evaluates your tool entirely through GitHub without visiting your marketing site, RB2B will not capture them.
What’s the difference between RB2B and LeadCognition?
The core difference is signal source. RB2B tells you who visited your website. LeadCognition tells you who engaged with your open-source repo or your category on GitHub — stars, forks, issues, competitor repo activity. For DevTool companies with active GitHub presence, LeadCognition captures the majority of evaluators that website-only tools miss. The two products are complementary; most DevTool teams benefit from running both.
Can I use RB2B and LeadCognition together?
Yes, and it’s the recommended setup for DevTool GTM teams. RB2B handles your bottom-of-funnel website visitors; LeadCognition handles your top-of-funnel GitHub evaluators. You get overlapping coverage only for the subset of developers who both starred your repo and visited your website — which is a useful overlap, since that combination is a very strong buying signal. Route each signal type to the appropriate playbook based on intent stage.
