happycapy
Pros
- + The live sandbox view showed every step of my research-and-file task — I could stop a wrong turn before it consumed credits.
- + One subscription spans models from several labs with per-task switching and no API keys to manage.
- + The Free plan (250 credits/month, no credit card) is enough to run several real multi-step tasks before paying.
- + Capy Mail lets tasks be triggered and answered by email, with approved-sender filtering and per-plan quota.
- + Sandbox resources scale clearly by plan (Max: 4 cores, 8GB RAM, 200GB storage) rather than being hidden behind a sales call.
Cons
- - Credits meter everything — model calls, media and Automations — and reviewers report heavy tasks run through monthly allowances fast.
- - Automations are beta and capped at 3 on Pro, undercutting the always-on automation pitch.
- - Named integrations stop at GitHub and Notion; the rest depends on community skills rather than maintained connectors.
- - No public API for programmatic control, and the exact included model count conflicts across the vendor's own materials and third-party pages.
- - Young product: review volume is thin, and users report lag in the live view and flaky scheduled runs.
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)
