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
Flowise
Pros
- + Node canvas gives LangChain-level control over retrieval, agents, and tools without writing code — my retrieval agent took one sitting
- + Self-host path is real: npm or Docker, minutes to localhost:3000, Apache 2.0 core license
- + Human-in-the-loop review nodes make the agents-propose-humans-release pattern easy to wire
- + Wide model and vector-store support (100+ LLMs, embeddings, vector DBs per the vendor) keeps you off proprietary lock-in
- + Evaluations, metrics, and run observability are built into the builder rather than bolted on
Cons
- - Node picker presumes you understand embeddings, chains, and retrieval strategies — beginners are lost quickly
- - Production self-host means doing your own persistence, secrets, queue/workers, and uptime — time not visible in the free price
- - Enterprise identity and permission features live under a commercial license inside the same repo
- - Cloud free tier (100 predictions/month) is too small to judge real performance
- - Fast-moving node surface and uneven community templates mean upgrades can break flows
