What Cendor is
Modern LLM applications keep re-solving the same unglamorous problems: assembling context, keeping prompts and cost in budget, testing without burning tokens, and leaving an audit trail. Cendor packages those as small, composable libraries you plug in under any framework — not another framework to adopt.
The pipeline reads like the lifecycle of a request: contextkit assembles it, squeeze compresses it, tokenguard budgets it, cassette records and replays it for tests, and acttrace writes a tamper-evident audit trail — all on core, the small seam and event bus they cooperate through. The tools never import each other; they only meet at core. See the libraries or run the whole stack in your browser on the Try page.
One brand, two doors
You can adopt Cendor two ways. Reach for the six libraries when you want to slot one primitive under your existing stack, or start with the SDK — a governed agent loop with budgets, tamper-evident audit, PII redaction, and replay built in from the first line. Both ship in Python (on PyPI) and TypeScript (on npm); the parity matrix is the contract between them, not matching version numbers.
The honest-claims rule
Cendor's whole reason to exist is trust in the plumbing, so the project holds itself to one rule: every public number is benchmark-backed. We never overstate coverage or compliance. The audit tooling produces evidence to support compliance work — it is not a compliance guarantee and is not legal advice. When something is Python-only or not yet ported, the docs say so plainly. The numbers behind the claims live on the benchmarks page.
