NGI Zero Commons Fund April 2026 round

NLnet Foundation announced the April 9, 2026 NGI Zero Commons Fund round (the ninth open call) with 57 free and open source projects funded for a total of approximately €1.4M (~$1.5M). NLnet operates the Commons Fund as a rolling bi-monthly call with grants between €5,000 and €50,000 per project (with scale-up available), making it one of the few EU-level public funders running a sustained small-grants pipeline.

The 57-project portfolio skews three ways: trustworthy hardware and manufacturing (10 projects including Topola Autoplacer for PCB component placement, BrailleRAP open-source Braille embosser, GLOW-SG13G2 digital standard cell library for chip design, Padne power delivery network analysis, PowerCommons OpenPower processor core revival, and Yanartas open-source hardware security module); network infrastructure (Bromal lightweight Matrix server, mgmt config automation, YunoHost self-hosting with OIDC); and software engineering and protocols (13 projects including Python OpenPGP library, XMPP-Matrix gateway, SPARQL query evaluation tools, and protocol verification). Operating systems and firmware (6 projects, including LinuxBoot, bhyve hypervisor, Managarm microkernel) and data/AI/analysis (8 projects including document conversion, satellite imagery aggregation, PDF redaction) round out the cohort, with 17 user-facing applications including federated video platform Loops and DAW Zrythm.

Funding is from the European Commission's Next Generation Internet programme via DG CNECT (grant agreement No. 101135429) and the Swiss State Secretariat for Education, Research and Innovation. NLnet's overall NGI Zero commitment for 2026 through 2027 is €21.6M across all open calls. Projects must publish under a free or open source license; outputs become part of the European digital commons. The thirteenth call opened April 1, 2026 with a deadline of June 1, 2026 at 12:00 CEST.

Eligibility is open to individuals and organizations of any type, which means the small-grant tier reaches solo maintainers and tiny collectives that mainstream grant pipelines cannot underwrite. The result is a pipeline that funds protocol-layer, hardware, and digital-commons work mostly invisible to U.S. AI-funding discussions but central to the EU's digital sovereignty story.

For a sovereignty-minded reader, NGI Zero is among the few EU-scale public funders running both the protocol and hardware layers as first-class targets rather than as add-ons to a model-funding pipeline. The bi-monthly cadence (six-plus calls per year) makes the program a usable continuous funding source for open-source maintainers rather than a one-shot RFP.
