5 Best Sauna.ai Alternatives in 2026
Sauna.ai pitches itself as “the first multiplayer AI” — a team agent that learns how you work, remembers context, and runs in the cloud around the clock, reachable over iMessage, Slack, email, and its Mission Control dashboard. It’s genuinely capable, especially for engineering teams living in Linear, GitHub, and Jira. The friction shows up in three places: pricing is credit-metered and steep (a free tier of 100 credits/day, then Base at $99/month, Pro at $299/month, and Team at $999/month), the product is built team-first rather than for a single person, and getting real value means routing your work through Sauna’s surface and credit budget. Here are five alternatives.
1. Carly
Carly is an AI assistant you reach over email or text. Instead of asking you to adopt a new dashboard and watch a credit balance, Carly works inside the channels you already use. Forward an email, text Carly a request, or CC it on a thread — and the agent acts across 200+ integrations including calendar, CRM, Notion, Slack, and Drive, firing on real triggers 24/7 in the cloud.
What makes it different from Sauna.ai: Sauna is a multiplayer agent built around its own Mission Control and a per-seat credit budget. Carly is your personal assistant in the inbox — no new app to live in, and it drafts and sends email across Gmail and Outlook, not just dev-tool tickets.
Best for: Individuals and small teams who want an AI assistant that works in their existing channels without metering every action.
Pricing: Free, unlimited Zapier-style workflows; AI agents from $35/month
2. Lindy
AI executive assistant you reach over iMessage and email — it triages your inbox, schedules meetings, drafts replies in your voice, and chains actions across connected apps.
What makes it different from Sauna.ai: Lindy and Sauna are the closest match on shape — both are autonomous, both reach you over iMessage. Lindy leans toward the solo executive-assistant use case, while Sauna leans toward multiplayer team workflows and developer tools. If you want a personal EA over a team console, Lindy fits better.
Best for: Solo operators who want an autonomous EA over iMessage rather than a team agent.
Pricing: Free tier; paid plans by usage
3. Dust
Build and deploy AI agents on top of your company’s data and tools — connect Notion, Slack, GitHub, and internal docs, then spin up assistants for support, research, or engineering.
What makes it different from Sauna.ai: Dust is the closest to Sauna’s “agents across 3,000 tools for a team” pitch, but it’s builder-first — you assemble agents against your data rather than chatting with one over iMessage. Sauna is more turnkey and conversational; Dust gives you more control and is usually cheaper per seat.
Best for: Teams that want to build custom internal agents on their own knowledge base.
Pricing: From ~$29/user/month
4. Cassidy AI
Team AI assistant that connects your company’s tools and knowledge, then runs workflows and answers questions grounded in your data.
What makes it different from Sauna.ai: Both target teams, but Cassidy centers on knowledge-grounded assistants and workflow automation rather than an always-on agent reachable over iMessage. If your need is “answer from our docs and automate repetitive flows,” Cassidy fits; if it’s “an autonomous teammate that acts on its own,” Sauna leans closer.
Best for: Teams that want AI grounded in their internal knowledge plus workflow automation.
Pricing: Free tier; paid plans for teams
5. alfred_
Autonomous AI assistant for Outlook — overnight email triage, voice-matched draft replies, task extraction, and a morning Daily Brief.
What makes it different from Sauna.ai: alfred_ is a focused, transparently-priced email-and-calendar autopilot, not a multi-tool team agent. If your real problem is inbox overload (and you’re on Outlook) rather than orchestrating 3,000 tools across a team, alfred_ is a far cheaper, more targeted fit.
Best for: Outlook users who want overnight email processing without team pricing.
Pricing: $24.99/month

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
