Open Babel vs Sanity: at a glance
What is Open Babel?
Six years quiet, then a feature release and a fuzzing-driven security cleanup.
Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.
What is Sanity?
Sanity is paying down its runtime weight while wiring agents into the content layer.
Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

◆ Current state
Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.
◆ Where it's heading
The project has re-engaged around two things at once — improving initial 3D structure generation, and hardening the format parsers that make Open Babel useful in the first place. Because it reads dozens of chemical file formats, often from untrusted sources, the parser surface is the attack surface, and the release notes now devote as much space to crash fixes as to chemistry. The project says more bug-fix releases are expected through 2026.
◆ Prediction
Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.
Sanity
6.3DEVOPS
Sanity is paying down its runtime weight while wiring agents into the content layer.
◆ Current state
Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.
◆ Where it's heading
The MCP server is being hardened into a supervised write path rather than a read-only convenience: patches roll back as a unit, malformed IDs are rejected up front, and schema deploys now refuse to touch a Studio-managed workspace even when stale state says otherwise. That last rule is the direction in miniature — agents are being given real write access, fenced off by workspace ownership. Meanwhile the frontend packages are absorbing a breaking release to make bundle size a property of what you import rather than what ships.
◆ Prediction
The v4.0.0 notes state that more components move off runtime CSS-in-JS across the 4.x minors, so the bundle work continues incrementally rather than in another breaking jump. On the SDK side the presence release explicitly defers rendered remote selections to a forthcoming Portable Text plugin — the most concretely signposted next item in the feed.
