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)
E2B
Pros
- + Sub-second sandbox startup in my quickstart runs — create, execute, and read files felt like spawning a process, not provisioning infrastructure
- + Firecracker microVM isolation with outbound network controls kept agent-generated code away from my credentials and services
- + Per-second billing with storage included and a public workload estimator — I could model my ~$166/month usage case before adding the Pro base fee
- + Hobby tier is a real evaluation: $0 with a one-time $100 usage credit, no credit card, 20 concurrent sandboxes
- + Python and JavaScript SDKs with pause/resume persistence and prebuilt dependency templates shorten integration to an afternoon
Cons
- - No local-only mode — the core product assumes cloud connectivity, which fails airgapped requirements without an enterprise deal
- - Per-second CPU/RAM billing punishes sloppy sandbox lifecycle management; idle open sandboxes keep metering
- - Concurrency ceilings (20 on Hobby, 100 on Pro) require paid add-ons for larger fleets — up to 1,100 concurrent on Pro+
- - Deliberately narrow: no agent orchestration, memory, or model routing included — bring your own framework
- - Some integrations (the Vercel AI SDK 7 sandbox package) were marked experimental in the docs at time of writing
