Sauna by Wordware
Pros
- + Wordware v1's build loop is real: I described a workflow and had a versioned, deployed API endpoint in about fifteen minutes
- + Prompt version control on v1 is genuinely useful — every instruction change is tracked and revertible
- + Published v1 pricing from $0 to $1,999/month with explicit credit allowances beats the opaque enterprise-sales pattern
- + Sauna's design bet (persistent queryable context, spaces with rules, human approval on every action) addresses the right failure modes for AI workspaces
- + The company's pedigree is concrete: YC, a $30M seed led by Spark Capital, and 3,000+ integrations plus custom MCP connectors planned for Sauna
Cons
- - Sauna is waitlist-only as of October 2026 — the flagship product cannot be evaluated, bought or independently reviewed today
- - Wordware v1 is a legacy line after the 2025 pivot; building production agents on it means building on a platform the vendor has moved past
- - Credit consumption outruns the headline allowances on multi-step agents in my testing; budget per run, not per seat
- - SOC 2 and HIPAA compliance on v1 are gated behind the $1,999/month Infrastructure tier
- - No independent reviews, benchmarks or case studies exist for Sauna — the evidence base is entirely company-produced
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)
