7 Best Email Scraper Projects on GitHub with Strong Community Support in 2026
Discover the best email scraper projects on GitHub with active communities, useful features, and strong user adoption. Compare top open-source email extraction tools in 2026.
Best Email Scraper Projects on GitHub with Strong Community Support
Open-source email scrapers remain popular among developers, marketers, researchers, and cybersecurity professionals who need to extract publicly available contact information from websites. GitHub hosts hundreds of email extraction projects, though, which makes it hard to tell which repositories are actually maintained, trusted, and useful versus abandoned or barely tested.
This guide covers seven email scraper projects on GitHub, each with a real, currently live repository you can check yourself, what they’re actually good at, and who they fit best. It also covers what to check before trusting any open-source scraper with real work.
Always comply with local privacy laws, website terms of service, GDPR, CAN-SPAM, and other applicable regulations when collecting or using email addresses.
What makes a good email scraper project
A quality email scraper project typically includes active maintenance, clear documentation, positive community engagement, export capabilities (CSV, JSON, Excel), efficient crawling, email validation, and sensible error handling with duplicate removal. The best projects focus not only on extracting emails but on keeping the data usable afterward.
1. Email Scraper Tool by Adrian Tomin
A Python-based crawler that recursively visits web pages and extracts email addresses using pattern matching and automated link discovery. It’s frequently recommended for its simplicity and clean architecture, and works well for educational use and small-scale scraping tasks. Best for Python learners, small business research, and basic lead discovery.
2. theHarvester
theHarvester is one of the most widely used open-source OSINT tools in security work, not built specifically as an email scraper but capable of pulling emails, subdomains, hosts, and employee names from public sources like search engines and PGP key servers. It’s actively maintained, has a large user base among penetration testers, and is a genuinely more established project than most single-purpose scrapers on this list. Best for OSINT investigations, reconnaissance work, and anyone who wants a tool with a real security-community track record behind it.
3. EmailHarvester
A search-engine-based email harvesting tool that queries multiple search engines to compile email addresses tied to a target domain. It’s a straightforward, single-purpose Python tool without the broader OSINT feature set of theHarvester. Best for quick, targeted domain-specific email discovery.
4. Email-Scraping by Ayush Agarwal
This project focuses on bulk website processing, letting you scan multiple domains and collect unique email addresses in one pass. Its simplicity and scalability make it a reasonable fit for anyone managing lookups across several sites at once. Best for agency research, market analysis, and bulk prospecting.
5. Email-Harvester by eyuelberga
A simpler, more minimal domain email collector aimed at straightforward extraction jobs without a large feature surface. Best for lightweight, single-domain collection where you don’t need a full OSINT toolkit.
6. GHunt
GHunt is a well-known OSINT tool focused specifically on Google accounts, pulling public information tied to a Gmail address or Google account, including, in many cases, associated contact details. It’s a different angle from straightforward web crawling and is popular in the OSINT community specifically for Google-account investigation. Best for OSINT work centered on Google accounts rather than general website scraping.
7. MailGrab
MailGrab is a Python-based email harvesting tool built to automatically discover URLs, collect emails across them, and store the results for later processing, aimed at users who want a more automated workflow with less manual intervention. We’ve covered it in more depth in our dedicated MailGrab post. Best for marketing research, larger website networks, and automated workflows.
How to evaluate GitHub email scraper projects yourself
Before using any repository, check its activity: recent commits, active issue discussions, a maintainer who actually responds, and documentation that’s kept current. An inactive project can stop working quickly as websites change their markup or add new anti-scraping measures.
Community signals matter too: stars, forks, open pull requests, and real discussion in the issues tab are a reasonable proxy for whether other people have actually put the tool to use, not just starred it in passing. And check the documentation itself: a project with a real installation guide, usage examples, and a troubleshooting section is much less likely to waste your time than one with a bare one-line README.
Legal and ethical considerations
Email scraping sits in a legal gray area depending on jurisdiction and how the data gets used. Scrape only publicly available information, respect robots.txt where it applies, follow the target website’s terms of service, comply with GDPR and other relevant privacy regulations, and avoid unsolicited mass outreach with whatever you collect. Collecting data responsibly protects you and whoever you’re collecting it about.

Final thoughts
The best email scraper projects on GitHub combine active maintenance, clear documentation, and reliable extraction. Email Scraper Tool is a reasonable starting point if you’re new to this. theHarvester and GHunt are worth a look if your actual goal is OSINT reconnaissance rather than plain contact scraping, since both come from that community specifically rather than being general-purpose scrapers relabeled for it.
When choosing a project, weigh maintenance status and community activity more heavily than the feature list. A well-maintained repository with fewer features will usually outperform an abandoned one with more.
