How do I find a company's tech stack from GitHub?

Enter the company's GitHub organization name in the tool above. It fetches their public organization profile and top 10 repositories by stars, then shows the primary programming language for each repo and aggregates them into a language breakdown chart. Most technology companies — especially DevTool, SaaS, and software companies — have active GitHub organizations that reveal their core technology choices.

Why does tech stack matter for B2B sales?

A company's tech stack is one of the strongest indicators of what tools they're likely evaluating next. If a company's top repos are TypeScript-heavy, they're more likely to adopt TypeScript-native infrastructure tools. If they're using a specific database or framework, they're qualified for complementary developer tools. LeadCognition uses tech stack signals from GitHub to generate more relevant, personalized outreach messages.

Why does the language breakdown only show one language per repo?

GitHub's repository list API returns the primary language for each repo — the language with the most code. A repo might use TypeScript for the app and Go for tooling, but will show as TypeScript. For a full language breakdown per repo, the GitHub Languages API can be called separately. LeadCognition's platform goes deeper, cross-referencing tech stack signals with developer enrichment data.

Can I monitor when companies add new repos or switch tech stacks?

This tool provides a point-in-time snapshot. For continuous monitoring — tracking when a company forks your competitor's repo, opens issues on tools in your category, or adds developers who match your ICP — LeadCognition monitors GitHub events in real time and alerts you to high-intent signals.

How does this help with developer-led sales?

Understanding a company's tech stack lets you personalize outreach around their actual tools. Instead of generic messaging, you can reference their use of specific frameworks or identify capability gaps your product fills. Combined with LeadCognition's GitHub signal monitoring — which identifies developers evaluating tools in your category — tech stack data enables highly targeted, contextual outreach.

Free Developer Tool

Company Tech Stack Lookup

Enter any GitHub organization name to explore their public repos, top programming languages, stars, and forks.

Uses GitHub's public API. 60 requests/hour per IP. Uses 2 API calls per lookup.

GitHub org

Inspect public repos

Public repositories reveal languages, frameworks, open-source footprint, and engineering priorities.

Website tools

Check visible stack

BuiltWith-style checks are useful for frontend and marketing stack, but often miss backend and infra choices.

Signal monitoring

Track evaluation behavior

Repo events show when a team is exploring adjacent tools, competitors, or infrastructure categories.

Fit

Qualify compatibility

A TypeScript-heavy company is more likely to care about TypeScript-native tools than a team standardized elsewhere.

Personalization

Reference real context

Mentioning an actual repo or framework beats generic persona-based outreach.

Timing

Catch evaluations

Forks, issues, and adjacent repo activity can reveal active evaluation before website intent appears.

What GitHub organizations can I look up?

Any public GitHub organization with repositories. Try the company name, product name, or GitHub org handle.

Is this enough for sales targeting?

It is a useful snapshot. LeadCognition adds continuous monitoring, company mapping, and contact enrichment.
