We cover Airtable price backlash and the OSS alternatives filling the gap (NocoDB, Baserow, Grist, Teable), the AI-first crowd (Rows, Coda, Excel Copilot, Sheets Gemini), the data-analysis crossover (Sigma Computing, Equals, Brex-acquired Numeric), and the Japanese powerhouse kintone (Cybozu) plus Korean/Japanese form-and-workflow patterns. Relational vs Excel-style formulas, the blur with ETL/BI, self-hosting vs SaaS, and what AI actually changes.

Airtable의 가격 논란과 그 빈 자리를 채우는 OSS 알트(NocoDB·Baserow·Grist·Teable), AI-first 시도(Rows·Coda·Excel Copilot·Sheets Gemini), 데이터 분석 영역과 겹치는 Sigma Computing·Equals·Numeric(2026년 인수), 그리고 일본의 강자 kintone(Cybozu)과 한국·일본 시장의 폼/워크플로우 사례까지. 관계형 vs Excel 수식, ETL/BI와의 경계, 셀프호스팅 vs SaaS, AI가 실제로 무엇을 바꾸는지를 정리한다.
