Kilo AI
Pros
- + Model inference is billed at the providers' exact list prices with zero markup; the only surcharge is a 5% fee on card credit purchases (kilo.ai/pricing, checked October 2026)
- + Agent, extension, and CLI are MIT-licensed and fully readable on GitHub — 27,380 stars, 3,178 forks, TypeScript, built in the open (api.github.com/repos/Kilo-Org/kilocode)
- + Covers every surface I want: VS Code (1.66M Marketplace installs), JetBrains, CLI, cloud agents billed per second, PR code review, plus a beta desktop app and iOS companion
- + Request inspector shows context-window consumption and the full outgoing prompt per request — in my 12-file refactor session this made context degradation debuggable instead of mysterious
- + Bring-your-own-keys and local models (Ollama, LM Studio) mean the free platform plan is genuinely usable without paying Kilo anything for inference
Cons
- - Costs split across four ledgers — platform plan, inference, optional Kilo Pass subscription, and per-second cloud compute — which makes month-end reconciliation harder than competitors' single invoice
- - VS Code Marketplace rating is 3.89/5 from 217 reviews despite 1.66M installs, and the repo carries 534 open issues; the polish level trails the feature breadth
- - Release cadence borders on churn: multiple builds of 7.8.17 were pushed on a single day (23 October 2026), and the orchestrator agent is already deprecated
- - No built-in review agent inside the editor or CLI — code review is a separate cloud product at $0.33/hour (kilo.ai/docs)
- - Marketing contradicts itself on Auto Model ('smart model routing' versus 'Kilo does not have an auto model') and on developer counts (3M in Anaconda's release versus 5M+ on kilo.ai/cloud)
Stagehand
Pros
- + MIT-licensed SDK runs locally against any Chromium browser; in my test the act() call re-resolved after I rewrote a login button's classes and wrappers, while my hand-written Playwright selector broke
- + extract() returns schema-validated typed data (pydantic/Zod/struct) — pulling an invoice table into typed fields removed the JSON cleanup step entirely
- + observe() hands back real selectors, so I filled login credentials with ordinary Playwright calls and the secrets never reached the model
- + Full TypeScript, Python and Go support from one monorepo, with deep locators that reached nested iframes and a closed shadow DOM in my runs
- + Token cost per action is a fraction of screenshot-driven agents I have tested, because page context is a trimmed accessibility tree rather than images
Cons
- - Every act/extract/observe call is an LLM round trip — my ten-step workflow ran noticeably slower than the equivalent pure Playwright script
- - Code-only: no recorder or visual builder, so non-programmers cannot build or maintain automations
- - Anti-bot features (stealth, residential proxies, verified sessions) live in paid Browserbase plans, not the free SDK
- - Pages with canvas-rendered or heavily obfuscated UIs leave the accessibility tree thin and the AI primitives degrade
- - v4 is still moving fast; I pin versions because major upgrades have meant migration work
