Ceweb.br

What Ceweb.br does

Ceweb.br (Centro de Estudos sobre Tecnologias Web) is a non-profit web technology research center and department of NIC.br, the Brazilian non-profit entity that operates the .br domain registry under the governance of CGI.br. Founded in 2015 and headquartered in São Paulo, the organization coordinates the W3C Chapter Brasil and leads multistakeholder initiatives spanning web accessibility, open data, web standards, and AI governance. Its principal regulatory contribution is ABNT NBR 17225, a Brazilian accessibility standard for websites and applications aligned with WCAG 2.2, developed through ABNT/CB-040 with a working group of 178 specialists.

The center maintains a portfolio of open-source research tooling and datasets. MASTIF is a Multi-Agent System Testing Framework for comparing generative AI model combinations, agent communication protocols, and agentic frameworks. The Portuguese Emotion Recognition Dataset offers 40,000+ weakly-supervised annotated sentences across 28 emotion categories. Operational platforms include TIC Web Acessibilidade (which uses the ASES tool to verify compliance with Brazil's eMAG 3 accessibility model) and CORDATA, a metadata aggregation service for projects using open web data. Community-facing initiatives include the 'Mover-se na Web' call for vulnerable-community technology projects, the Conexão Povos da Floresta Amazon connectivity consortium (43 partners, 1M+ target beneficiaries), and the March 2026 launch of the 'Todos na Web: Acessibilidade em pauta' podcast (17 episodes).

Ceweb.br does not sell products or operate a commercial revenue stream; pricing is non-applicable and resources are sourced through NIC.br's domain registration and internet infrastructure operations. Its go-to-market is community-led, engaging developers, government entities, content creators, and research/civil-society organizations through events, training courses, podcasts, and direct participation in international forums such as the Internet Governance Forum (IGF).

Broad incumbents

• Mozilla Foundation: Non-profit advocating for an open, accessible internet through policy advocacy, grants, and standards engagement. Shares Ceweb.br's mission of keeping the web open and inclusive, though at much greater scale and with a broader product portfolio.
• W3C (World Wide Web Consortium): Global web standards body whose WAI (Web Accessibility Initiative) develops WCAG — the basis for Ceweb.br's ABNT NBR 17225. Ceweb.br is formally the W3C Chapter Brasil, making W3C its parent standards counterpart.
• World Wide Web Foundation: Non-profit founded by Tim Berners-Lee focused on advancing the open web as a public good. Comparable to Ceweb.br in web-advocacy and digital-inclusion framing, though globally scoped rather than Brazil-focused.
• Internet Society (ISOC): Global non-profit promoting the open development, evolution, and use of the internet. Shares Ceweb.br's multistakeholder governance orientation and active participation in forums like IGF.

Direct peers

• WebAIM (Web Accessibility In Mind): Non-profit based at Utah State University providing web accessibility training, evaluation tools, and research — directly comparable to Ceweb.br's accessibility standardization, training courses, and ASES evaluation tool work.
• Knowbility: Non-profit focused on digital accessibility for people with disabilities, providing training, advocacy, and community programs. Comparable to Ceweb.br in its mission to expand accessible web practices through education and standards-adjacent work.
• Cetic.br: Sister department within NIC.br producing statistics and research on ICT use in Brazil. Compares closely to Ceweb.br as a NIC.br research arm, though focused on statistical measurement rather than web standards.

Emerging players

• Open Data Institute (ODI): Non-profit working to build an open, trustworthy data ecosystem — directly comparable to Ceweb.br's CORDATA open-data platform and TIC Web Dados Abertos study of government open data practices.

Others

• IETF (Internet Engineering Task Force): Open standards organization developing internet protocols. While not focused on accessibility, IETF is an adjacent standards ecosystem participant and a reference point for how open, volunteer-driven technical communities operate — like Ceweb.br within the W3C.
