SQLite 版本迁移不再踩坑
上传你的 schema，3 秒发现 3.x → 3.y 的兼容性风险。50+ 规则覆盖 FTS5、WAL、JSON1。
Why SQLite Compatibility Matters Right Now
Every SQLite upgrade — from 3.30 to 3.45 — introduces subtle behavioral changes that can silently break your application. A recent Lobsters discussion (51 points, 20+ comments) revealed that developers regularly waste hours debugging issues caused by FTS5 query differences, WAL mode locking changes, or JSON1 function deprecations. The official changelog is exhaustive but requires manual cross-referencing; no automated tool exists to catch these regressions before they hit production.
Existing solutions fall short: DB Browser for SQLite and SQLite Expert focus on database management, not version drift. Generic migration tools like Flyway or Liquibase treat SQLite as an afterthought, with limited rule coverage. Developers are left comparing release notes by hand — a process that takes 2+ hours and still misses edge cases.
With SQLite’s adoption in edge computing, mobile apps, and serverless databases accelerating, the cost of incompatibility is higher than ever. The same Lobsters thread showed strong willingness to pay $10–20 for a tool that automates this check. Now is the perfect time to ship a focused, zero-install compatibility scanner — before the next upgrade cycle catches your team off guard.
How It Works
Paste or upload your schema
Copy your CREATE TABLE, CREATE INDEX, and other DDL statements directly into the editor, or upload a .sql file. Optionally select your current and target SQLite versions (e.g., 3.35 → 3.45) and any compile-time options like FTS5, JSON1, or WAL mode.
Instant compatibility scan
Our engine matches your schema against 50+ curated rules extracted from official SQLite changelogs. Each rule is tagged with severity: red for breaking changes, yellow for behavioral differences, green for safe patterns. The scan completes in under 3 seconds — no database connection required.
Get actionable migration report
Review a prioritized list of risks with concrete SQL fixes. For each issue, you’ll see the exact change needed — like replacing a deprecated function or adjusting a WAL mode setting. Export the report as a markdown file to share with your team or attach to your migration ticket.
What You Get
Automated rule engine
50+ hand-curated rules covering every breaking change and behavioral quirk from SQLite 3.30 through 3.45. Includes FTS5 tokenizer differences, WAL mode locking semantics, JSON1 function deprecations, and virtual table ABI changes — no manual changelog archaeology needed.
Fix-ready recommendations
Every risk comes with a copy-paste SQL snippet that resolves the incompatibility. For example, if your schema uses the deprecated json_each() path syntax, the tool shows the exact replacement using json_tree() with the correct arguments — saving you from hunting through release notes.
Zero install, private & free
All analysis runs in your browser — no data leaves your machine. No account, no signup, no hidden costs. Just open the page, paste your schema, and get your report in seconds. Built for developers who value speed and privacy above everything else.
