What Southern California Linux Expo does
Southern California Linux Expo (SCALE) is a Pasadena, California-based 501c3 non-profit organization that produces North America's largest community-run open source conference, held annually since 2002 at the Pasadena Convention Center. Organized by Linux Expo of Southern California Inc., SCALE operates with a core team of approximately 17 staff and draws on roughly 100 volunteers during event execution. The 23rd edition (SCALE 23x) is scheduled for March 5–8, 2026, spanning four days of sessions, workshops, and community activities across tracks including Applied Science, Developer, Embedded Linux, FOSS@Home, Kernel & Low Level Systems, Observability, Open Government, Open Source AI, Security, and Systems and Infrastructure.
The core offering is the annual multi-track conference supplemented by approximately 15 co-located specialized events (AstriCon, Cloud Native Days, DevOpsDay LA, PostgreSQL@SCaLE, Open Source Career Day, PlanetNix, Apereo Foundation's Open Source in Higher Education, KwaAi Summit, SunSecCon, Birds of a Feather sessions, Capture the Flag, Incident Response Competition, Fedora Hatch Day, Game Night, and Libre Graphics Day).

AWS provides web hosting and email infrastructure. Technical committees cover Networking/WiFi, Online Services, Audio/Visual, Training, and Diversity, with leadership distributed across named chairs.
SCALE generates revenue through two primary streams: tiered attendee registration ($80 early bird / $90 standard / $100 late for SCALE 23x) and corporate sponsorships structured across Platinum, Gold, Silver, and specialty tiers. Named sponsors include Microsoft, Google, Meta, Red Hat, AWS, Canonical, GitHub, Confluent, Clickhouse, Grafana Labs, ARM, Percona, TiDB, and others. The organization is explicitly vendor-neutral and distribution-neutral in outreach, maintaining a positioning distinct from commercial conferences.

Southern California Linux Expo competitors and assessment
Company assessmentDirect peers
- DEF CON: DEF CON is a long-running, community-run security/hacker conference with comparable volunteer scale, grassroots ethos, and tiered corporate sponsorship model. Its hacker/security community substantially overlaps with SCALE's security track audience.
- FOSDEM: FOSDEM is a community-organized, volunteer-run open-source conference held annually in Brussels. It is the most direct analogue to SCALE: free/cheap community-run event, broad Linux and FOSS developer audience, no single corporate owner, and similar vendor-neutral ethos.
- PyCon US (Python Software Foundation): PyCon is a community-organized, volunteer-run developer conference with a similar grassroots structure, tiered ticket pricing, and sponsor mix. It serves as a useful operating-model analogue for SCALE even though its topic focus is narrower (Python only).
- DevOpsDay LA: DevOpsDay LA is co-located with SCALE each year and shares the same community-organizing ethos. As a long-running (15-year) community-run tech conference in the same region, it is structurally and operationally very close to SCALE's co-located events.
Broad incumbents
- Red Hat Summit: Red Hat's flagship corporate conference directly overlaps with SCALE's enterprise Linux, cloud-native, and open-source audience, and competes for the same enterprise sponsorships. As a SCALE sponsor and ecosystem participant, it is a relevant adjacent incumbent.
- KubeCon + CloudNativeCon (CNCF): CNCF's flagship cloud-native conference competes for the same enterprise sponsors (AWS, Google, Microsoft, Red Hat) and developer attendees that SCALE courts through its Cloud Native Days co-located event, but at a global scale with substantially larger booth and sponsorship packages.
- GitHub Universe: GitHub's annual developer conference addresses a heavily overlapping developer/OSS audience and pulls from the same sponsor ecosystem as SCALE. It is a relevant commercial incumbent alternative for sponsors deciding how to allocate open-source marketing budgets.
- Open Source Summit (The Linux Foundation): The Linux Foundation's flagship open-source conference attracts many of the same sponsors and developer audiences as SCALE, but with foundation backing, global rotation, and significantly larger programming budgets. It competes for sponsor dollars and attendees in the same open-source ecosystem.
Others
- O'Reilly OSCON (historical) / O'Reilly Open Source Convention: OSCON was the historical corporate-owned North American open-source conference that SCALE's founders explicitly cited as a motivating alternative when launching SCALE in 2002. O'Reilly remains a relevant thematic peer via its conference and publishing business, even though OSCON itself is no longer running as a standalone event.
Regional players
- PostgresConf (United States Postgres Association): PostgresConf is the community-organized PostgreSQL conference that runs alongside PostgreSQL@SCaLE as a co-located event. It is a comparable community-run database/dev event model and shares sponsors (PostgreSQL, Percona, Crunchy) with SCALE.
