Check .FOO domain availability, register a new .FOO domain, search multiple names in bulk, or transfer your existing .FOO domains to NiceNIC. Built for developers, engineering teams, open-source maintainers, technical educators, prototype builders, agencies, and resellers.
Need lower .FOO pricing? Upgrade account level for bulk registration and reseller pricing.
A .FOO domain can support portfolios, prototypes, documentation, APIs, experiments, demos, status pages, and technical communities. Because .FOO is HSTS preloaded, HTTPS must work correctly from the first browser visit.
Add funds and pay for domain services using supported crypto options such as USDT, BTC, ETH, and LTC. Automated crypto deposit recording helps account balances update quickly after successful confirmation, with no extra NiceNIC processing fee for automated deposits.
NiceNIC provides real human support, not only scripted replies. Our team can review your domain needs, explain practical options, and give account-level, transfer, bulk registration, and reseller suggestions to help your domain business grow.
NiceNIC does not take arbitrary action against domains. Abuse reports are reviewed based on available evidence, policies, and registry requirements, with domain owners guided to review, fix, or explain reported issues where appropriate.
Manage .FOO together with 2,500+ domain extensions from one NiceNIC account, including country-code, generic, and new domain extensions. This helps businesses, investors, and resellers build global domain coverage more efficiently.
NiceNIC supports 47+ website languages, creating a multilingual registrar experience for international users and teams. This makes domain registration, renewal, transfer, account management, and support easier across different markets.
For hosting providers, agencies, platforms, and domain resellers, NiceNIC supports reseller API access for domain registration, renewal, transfer, DNS, account-level pricing, and custom nameserver services.
The September 9 DNS.Coffee zone-file snapshot shows 4,675 observed .FOO domains. Google Registry positions .FOO as a secure domain for developers, and the entire TLD is included on the HSTS preload list.

This view places the 2026-to-date .FOO zone-file snapshot within the wider domain market while keeping the observed-domain metric clearly labeled.
It turns a familiar programming placeholder into a recognizable technical identity.
“Foo” is widely recognized in programming examples and test data, making the extension memorable for portfolios, experiments, libraries, APIs, and technical education.
The TLD is HSTS preloaded, so browsers require HTTPS. This supports a secure baseline but also means certificates and redirects must be ready before launch.
Teams can separate prototypes, demos, labs, hackathons, and internal tools from production brands when the site clearly states its status and data-handling limits.
Because the 2021-2022 .FOO history contains only 34-35 observed domains before the public launch expansion, this same-source snapshot gives a more useful comparison with selected Google Registry extensions.
Public .FOO resale records with fully confirmed prices are limited, but concise developer, tool, library, API, framework, and project names can remain useful when the technical identity is clear.
Choose a registration, transfer, renewal, DNS, bulk, or reseller workflow that matches the project status, HTTPS deployment, data sensitivity, team ownership, and release process.
Show real projects, repositories, technical roles, contribution history, contact methods, and whether demos are experimental, archived, or actively maintained.
Separate test data from real customer data, disable unintended indexing where appropriate, publish limitations, and avoid presenting a proof of concept as a production service.
Document authentication, rate limits, versions, status, deprecation, data retention, examples, and support channels without exposing secrets in client-side code.
Manage product, lab, demo, client, and campaign domains through bulk search, transfer, and API-supported workflows.
If you already own .FOO domains elsewhere, transfer decisions should not be based only on one renewal invoice. Check transfer eligibility, ownership access, billing reliability, support response time, API needs, and long-term domain management.
Paste multiple .FOO names, remove duplicates, review the count, and continue to bulk registration. This is useful for domain investors, brand teams, agencies, hosting providers, and resellers.
Enter one name per line, with or without .FOO. The tool removes duplicates and prepares a clean list for bulk registration.
If your business sells hosting, websites, SaaS, agency services, or brand protection packages, NiceNIC reseller APIs can support domain registration, renewal, transfer, DNS, and account management.

Practical answers for developers using .FOO for projects, documentation, testing, APIs, and secure HTTPS websites.
Developers, engineering teams, open-source maintainers, technical educators, hackathon projects, prototype builders, API providers, and tool communities can use it when the programming association supports the identity.
Google Registry includes .FOO on the HSTS preload list. Compatible browsers require a secure HTTPS connection and will not allow users to bypass a certificate error through a normal HTTP fallback.
Prepare a valid certificate covering the exact hostname, HTTPS hosting, correct DNS, secure redirects, renewal monitoring, and testing for every subdomain that users may visit. Do not launch an HTTP-only placeholder.
It can be, but the playful developer meaning may suggest experimentation to some users. Use clear branding, uptime and support information, privacy terms, security contacts, and product documentation when the service is production-critical.
Prefer synthetic data, minimize collection, isolate test environments, restrict access, remove secrets, set retention limits, and clearly warn users when a demonstration is not intended for real personal, financial, medical, or confidential information.
Yes. Publish authentication requirements, versions, rate limits, status, deprecation, examples, data practices, and support contacts. Keep private keys, tokens, and internal endpoints out of public documentation.
The generic placeholder meaning does not eliminate risk in the full domain. Check the complete name against software, service, and brand trademarks, package names, repositories, app stores, and target markets before registration.
Usually yes, because a registrar transfer does not normally change hosting or DNS automatically. Still record nameservers, DNSSEC state, certificate issuance records, CAA records, redirects, and renewal ownership before using the NiceNIC transfer page.
Use the single-name search or bulk registration section for product, library, API, lab, demo, and defensive variations. Agencies and platform teams can use the reseller API for supported portfolio operations.
Register a new .FOO, transfer an existing domain, or upgrade your account level for bulk registration and reseller API use.
