Decision notes
Official-document research
Based on the cited documentation. We did not use the product, purchase a plan, or run quality, speed or reliability tests in this review.
Consider it for
- Developers able to inspect compressed context and provider routing
Choose another approach if
- Guaranteed lossless answers or mandatory no-upload defaults
Pricing and conditions
Contact sales for a quote
Apache-2.0 software has no license fee; local compute, storage and upstream model usage remain separate. Enterprise managed/VPC/security features require a quote; no amount, seat unit, currency, tax, regional price or overage was established. The advertised three free months require a 12-month Enterprise plan and eligibility, not an unconditional free service.
Pricing source read:
Pricing or terms sourceCode, model and service licensing
Code and the named kompress-v2-base weights use Apache-2.0; preserve notices and check dependencies and training-data terms separately. Local compression does not cover upstream LLM policies. Local telemetry is opt-in, but the separate default-on beacon uploads counters and provider/model identifiers; docs say it excludes prompts, completions, code and paths. Disable it if required. CCR originals persist until TTL/eviction; no blanket no-training or zero-retention assurance was established.
Basis and limits of the recorded score
Original 4.4/5 retained; no original scoring worksheet or hands-on evidence was available. Documentation does not validate this score.
Overview
Headroom supplies SDK/proxy processing for LLM context and tool outputs, using structured sampling and optional extractive Kompress text processing. Protected code and small inputs may pass through; results depend on content and configuration. The limitations page describes some figures as synthetic single-sample measurements, not a repeatable benchmark.
CCR caches originals for retrieval. The proxy defaults to local SQLite with a 1,800-second TTL and capacity eviction, so recovery is conditional. Compression is local, but model requests still reach the configured upstream and a separate anonymous upload beacon is enabled by default.

Pros / Cons
Pros
- SDK/proxy options and configurable pass-through gates
- Original retrieval while the CCR cache remains available
Cons
- No universal savings or answer-quality guarantee
- Cache expiry, upstream routing and default beacon need review
Who it's for
Evaluating JSON-heavy agent context handling
Adding controlled compression before an existing LLM provider
Bottom line
Useful to evaluate on your own payloads when cache, routing and data controls are acceptable.
