ProvelyProvely finds LangChain, LangGraph, LlamaIndex, OpenAI Agents, Vercel AI, OpenAI SDK, Anthropic SDK by itself, in TypeScript and Python. You add two lines. You write no guard call and import no adapter.
import { Provely } from '@provely/sdk';
new Provely();
from provely import Provely
Provely()
Each plugin loads only when its package is present. The core holds no framework code, so an app pays only for the framework it uses.
What did the grid measure?
The grid runs the same failure cases on 15 paths, in 4 columns. Each column is one language, for the frameworks or for the plain SDKs.
| Column | Paths | Pass | Fail | Not counted | Not applicable | Head |
|---|---|---|---|---|---|---|
| TypeScript frameworks | LangChain, LangGraph, LlamaIndex, OpenAI Agents, Vercel AI generateText, Vercel AI streamText | 27 of 27 (1 passes under guard_mode: enforce; observe records only; rules cases not yet measured) | 0 | 0 | 0 | 82acaae6 |
| Python frameworks | LangChain, LangGraph, LlamaIndex, OpenAI Agents | 26 of 27 (1 passes under guard_mode: enforce; observe records only; rules cases counted apart) | 1 | 0 | 0 | 9f9131ba |
| TypeScript plain SDKs | OpenAI Chat Completions, OpenAI Responses, Anthropic Messages | 24 of 27 (1 passes under guard_mode: enforce; observe records only; rules cases not yet measured) | 3 | 0 | 0 | d1aa85ea |
| Python plain SDKs | OpenAI Chat Completions, Anthropic Messages | 23 of 27 (1 passes under guard_mode: enforce; observe records only; rules cases not yet measured) | 4 | 0 | 0 | d1aa85ea |
A fail is a case that did not pass on at least one path. "Not counted" is a case where the framework coped alone and Provely made no fix, so it is not a pass. An inapplicable case is left out of the total.
The invented-value case passes under guard_mode: enforce; observe records only. Under observe, the default, Provely records the value and the write runs.
