## Browser Use

Browser Use frames an agent as two halves: a harness that decides what to do, and a browser that executes it. The harness reads the page, plans clicks and typing, and can fall back to raw JavaScript evaluation when needed; the browser is a real Chromium instance that renders pages exactly as a person would see them. You hand over an instruction like "buy trail shoes, size 42, under $120" and receive a result plus structured data.

The company publishes its benchmarks publicly, which is unusual in this category. Their stealth browsers are reported to get through on 90.5% of a 100-site test against several competitors, and their shopping agent completes 91.8% of 500 stores. The Browser Harness component is free and open source and is used as the browser tool inside Claude Code and Codex-style agents.

For teams that need to run at scale, Browser Use offers cloud or on-premise browsers, US or EU execution with EU runs staying in Frankfurt, SOC 2 Type II compliance, and HIPAA coverage on enterprise plans. Pricing is usage-based for the hosted services, with a small free credit to start.

**Pricing & Plans:** Freemium with usage-based paid tiers: web agents around $0.006 per task, stealth browsers around $0.02 per browser hour, and the Browser Harness free and open source. $1 in free credit on signup; enterprise and on-premise are contact-for-pricing.

- **Natural-language web agents:** Describe the task and get structured JSON back, handling multi-step flows behind logins without hand-written selectors.
- **Stealth cloud browsers:** Managed Chromium instances with residential IPs that are benchmarked for getting past bot detection and CAPTCHAs.
- **Browser Harness (open source):** A free, open-source harness that plugs into coding agents; benchmarked as the most token-efficient browser tool of the set tested.
- **Cloud or on-premise deployment:** Run browsers in your own network or in managed US/EU cloud regions, with EU data staying in Frankfurt.
- **Compliance and benchmarks:** SOC 2 Type II, HIPAA on enterprise plans, and public head-to-head benchmark results.

**Strengths:** Industry-leading benchmark results published openly; Open-source harness means no lock-in for local development; Usage pricing is granular and starts with a free credit; Enterprise-grade options: on-prem, EU residency, SOC 2 Type II

**Limitations:** Per-task and per-hour costs can add up quickly at high volume; Stealth browsing raises ethical and terms-of-service questions teams must handle; Cloud usage requires an API key and some engineering integration

## Cognitora

Cognitora is an open-source orchestration layer for distributed large language model inference, written in Rust. Rather than shipping a single inference engine, it joins the engines you already operate — vLLM, SGLang, llama.cpp, Apple MLX, a TRT-LLM spawn driver and its own preview cgn-infer engine — into one cluster behind a single OpenAI-compatible gateway. You can deploy it instead of an orchestrator such as NVIDIA Dynamo, and the project positions itself as supporting more engines, running on bare metal without Kubernetes, factoring power consumption into scheduling and avoiding a Python control plane.

Its core innovation is KV-aware routing. The router scores nodes by the longest-prefix overlap of sequence-chained BLAKE3 digests, using cache claims that agents report in heartbeats. In real llama.cpp runs the router reportedly added 0.9–2.0 ms at p50. Beyond routing, the platform splits prefill from decode across separate pools (handing KV cache off through NixlConnector), maintains a multi-tier RAM/SSD KV cache with cross-node QUIC fetch, and offers pluggable offload backends including nixl, lmcache, hicache and kvbm.

The stack is modular: cgn-router for routing, cgn-agent to supervise engines on each node, cgn-kvcached for tiered caching, cgn-metrics for Prometheus plus Redfish/NVML power telemetry, cgn-ctl as an admin CLI, an optional Kubernetes operator, and a preview native engine. Energy-aware scheduling drains hot nodes, a closed-loop autoscaler reacts to power readings, and gossip-based discovery removes the need for etcd. Security options include optional mTLS, SHA-256 checksummed releases and OIDC or scoped API-key auth. The project ships six static binaries for systemd installs, Helm charts for Kubernetes, and a single-file HTML cluster dashboard that visualises throughput, latency percentiles, KV utilisation and joules per token without Grafana.

**Pricing & Plans:** Cognitora is open source and installs from its repository; there is no published per-seat or per-token price. Deployment cost is your own hardware, so total spend depends on the GPUs and nodes you run.

- **KV-aware request routing:** Routes each request to the node whose cache holds the longest matching prompt prefix, using longest-prefix overlap of BLAKE3 sequence digests to avoid repeated prefill work.
- **Engine-agnostic gateway:** One OpenAI-compatible API in front of vLLM, SGLang, llama.cpp, Apple MLX and a TRT-LLM spawn driver, so you can mix engines inside a single cluster.
- **Prefill/decode disaggregation:** Runs prefill and decode on separate replica pools with KV handoff through NixlConnector, letting each phase use hardware suited to it.
- **Energy-aware scheduling:** Folds Redfish and NVML power readings into routing scores, applies soft per-node watt caps, and drains hot nodes automatically to cut energy per token.
- **Bare metal to Kubernetes:** Deploys as six static binaries under systemd without Kubernetes, or with an optional kube-rs operator exposing InferenceCluster, ModelPool and RoutingPolicy CRDs.

**Strengths:** Open source and self-hostable, with no per-token or per-seat licensing cost; KV-aware routing meaningfully reduces duplicated prefill work across a fleet; Works with many engines, so it does not lock you into one vendor's runtime; Runs on bare metal without Kubernetes, keeping the operational surface small

**Limitations:** Requires substantial LLM infrastructure knowledge and hands-on GPU hardware to evaluate; Several headline capabilities are on the main branch but not yet in a tagged release; TRT-LLM support is a spawn driver only, without a default recipe or CI GPU test
