Sanity vs Weaviate: at a glance
What is Sanity?
Sanity ships across every package at once, and the agent-facing surface moves fastest.
Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.
What is Weaviate?
Weaviate is tuning the agent, not the database — Search Mode now has effort tiers.
Since the 1.38 release took the HFresh disk-based index and the built-in MCP server to general availability, the visible work has moved up the stack. The Query Agent's Search Mode gained medium, high and ultrahigh effort tiers, letting callers trade latency for thoroughness on a per-query basis. Query profiling returns per-stage, per-shard timing so a slow query can be diagnosed rather than guessed at. The remaining entries are a two-part Foundry series arguing that folders, tags and keyword search break down in creative workflows, plus an ingestion guide covering server-side batching and the blobHash type.
Sanity vs Weaviate: editorial side-by-side
Sanity
7.5DEVOPS
Sanity ships across every package at once, and the agent-facing surface moves fastest.
◆ Current state
Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.
◆ Where it's heading
The MCP server is where the capability surface is actually growing — asset upload, schema discovery, CORS management — each release handing agents another operation that previously needed a human in the dashboard. The library work underneath is consolidation: one module system, one supported Node line, fewer dependencies, and now one SDK shared between Studio extensions and standalone apps. Read together, Sanity is narrowing the number of ways to build against it while widening what an agent can do unattended.
◆ Prediction
Expect the MCP tool list to keep absorbing dashboard operations — deploy, dataset and role management are the obvious remaining gaps — and the ESM-only floor to propagate to the packages that have not taken it yet. The releases are per-package, so a single dated entry rarely tells the whole story of a given week.
Weaviate
5.0DEVOPS
Weaviate is tuning the agent, not the database — Search Mode now has effort tiers.
◆ Current state
Since the 1.38 release took the HFresh disk-based index and the built-in MCP server to general availability, the visible work has moved up the stack. The Query Agent's Search Mode gained medium, high and ultrahigh effort tiers, letting callers trade latency for thoroughness on a per-query basis. Query profiling returns per-stage, per-shard timing so a slow query can be diagnosed rather than guessed at. The remaining entries are a two-part Foundry series arguing that folders, tags and keyword search break down in creative workflows, plus an ingestion guide covering server-side batching and the blobHash type.
◆ Where it's heading
The database work is largely banked; what is being iterated now is the agent layer sitting on top of it, and effort tiers are the clearest sign Weaviate treats retrieval quality as a dial rather than a fixed property. Query profiling serves the same shift — once agents issue the queries, humans need a way to see where time went. The Foundry posts are positioning for that same audience: retrieval as the replacement for manual file organisation.
◆ Prediction
Expect the effort tiers and profiling to converge — surfacing the cost of a chosen tier — and the Boost API and nested object filtering previews from 1.38 to reach general availability.
