# Top Relevance AI Alternatives

Relevance AI lets you build custom AI agents and group them into multi-agent workforces, but it only sells one plan now, Enterprise, and you have to book a sales call to get a price. That pushes a lot of buyers to look at tools that either publish real prices or skip the building step entirely with pre-made AI employees.

The three real substitutes here split into two camps. Lindy is the closest match to Relevance AI's own job, building custom agents, but with published per-seat pricing. Marblism and Sintra skip the build step and sell you a set of pre-named AI employees for a flat or bundled price instead.

## Verdict

- If you want to keep building custom, multi-step agents and choosing which AI model runs them, but want published pricing instead of a sales call, choose Lindy. Lindy's Agent Builder covers the same custom-agent job as Relevance AI, and its per-seat pricing is published instead of requiring a sales conversation, though picking the underlying model requires stepping up to Lindy's $99.99/mo Pro plan, not the $49.99 Plus entry tier.
- If you want one flat bill that covers inbox, social, lead gen, SEO, and call answering without building any workflows, choose Marblism. Marblism's six pre-built AI employees are ready to use for one flat price with unlimited team members, and every draft waits for your approval before it goes out.
- If you're a solo founder or small team on a tight budget who just needs pre-built marketing and support help, choose Sintra. Sintra's 12+ helper bundle starts at $15.60 a month prepaid annually, well below Lindy's entry price and far cheaper than an Enterprise-only quote from Relevance AI.
- If you need agents to hand off work to each other across sales, support, and ops, or you rely on Relevance AI's 2,000+ integrations and SSO/RBAC controls, choose stay on Relevance AI. none of Lindy, Marblism, or Sintra offer a multi-agent handoff model or an integration count close to Relevance AI's, so switching would mean losing that setup.

## Ranking

1. Lindy (https://topalternatives.to/tools/lindy)

   Lindy is the closest match to Relevance AI's actual job: building custom, multi-step AI agents rather than picking a pre-named role off a shelf. Its Agent Builder lets you describe a workflow in plain language, and Pro and Max plans let you pick which AI model runs each agent, mirroring Relevance AI's multi-model setup. Lindy also publishes real prices, $49.99 to $199.99 per seat per month, which beats booking a sales call just to find out what Relevance AI costs. The tradeoff is that usage limits are described only as multiples of the Plus plan (3x, 7x) rather than a fixed number of tasks, so you won't know your real ceiling until you hit it. Enterprise pricing with SSO and HIPAA is still quote-only, same as Relevance AI. Lindy fits founders who want to keep building agents but with a lighter, cheaper entry point than Relevance AI's enterprise-only plan.

2. Marblism (https://topalternatives.to/tools/marblism)

   Marblism trades Relevance AI's build-your-own-agent model for six ready-made AI employees: an inbox manager, a social poster, an outreach rep, an SEO writer, a call answerer, and a contract reviewer. You don't configure anything, and one flat price covers unlimited team members and unlimited businesses, a real change from Relevance AI's usage-metered Enterprise billing. Every plan includes 50 hours of AI work a month, and drafts wait for your approval before sending, so a bad AI output doesn't go out under your name. The catch is the 50-hour cap: teams running high-volume outreach or content will burn through it and need paid top-ups. Marblism doesn't advertise an API or a visual workflow builder either, so if what you actually need from Relevance AI is the ability to design custom multi-agent handoffs, Marblism isn't built for that. It fits best as a flat-fee swap for teams that want six specific jobs covered without building anything.

3. Sintra (https://topalternatives.to/tools/sintra)

   Sintra covers a wider set of named roles than Marblism, 12+ helpers spanning support, copy, data, email, social, and SEO, chatted with individually rather than assembled into a workflow. It's the cheapest of the three real alternatives: $15.60 a month prepaid annually, versus Relevance AI's sales-call-only Enterprise plan and Lindy's $49.99 minimum. It's one account-level bundle, not per-seat pricing, and every helper draws from a shared pool of 250 monthly credits, so heavy users will need to budget for top-ups, and buying a single helper standalone costs more than the whole bundle. Sintra has no visual automation builder and no open API, so it's not a fit for teams that actually use Relevance AI to wire agents into their own systems. It works best for non-technical operators who want to brief an AI helper the way they'd brief a freelancer, not build one.


## Segments

- Best builder-style substitute: lindy. The only alternative built for custom, multi-step agents with a choice of AI model, the closest match to how Relevance AI itself works.
- Best value: sintra. Lowest published starting price at $15.60/month prepaid annually.
- Best for approval-gated work: marblism. Drafts across inbox, social, and outreach wait for your sign-off before anything sends.

## Why teams switch

- Credit-based billing makes costs hard to predict. Reviewers say the dual-meter billing (Actions plus Vendor Credits) produces high and unpredictable costs, with credit balances draining fast on misconfigured or high-volume workflows. Sources: https://www.11x.ai/guides/relevance-ai-review
- Pricing at scale is a common complaint. A buyer review flags that credit-based pricing gets expensive with active, high-volume agents, calling out pricing at scale as a main concern. Sources: https://makerstack.co/reviews/relevance-ai-review/
- No published price, so budgeting takes a sales call. The public pricing page shows only a custom Enterprise tier with no listed price. Teams that want to compare costs before talking to anyone have to book a demo first. Sources: https://relevanceai.com/pricing

## FAQ

### What's the cheapest Relevance AI alternative?

Sintra is the cheapest of the real alternatives, starting at $15.60 a month prepaid annually. Marblism's annual plan is close behind at $24/month.

### Is there a free alternative to Relevance AI?

No. None of the closest alternatives, Lindy, Marblism, or Sintra, offer a free-forever plan. Lindy has a 7-day trial and Marblism and Sintra offer money-back guarantees instead of free tiers.

### Which Relevance AI alternative is easiest to set up without an engineer?

Sintra and Marblism are both pre-built: you chat with named AI employees for specific roles instead of assembling a workflow, so there's no agent-building step like there is with Relevance AI or Lindy.

### Does any Relevance AI alternative let me choose which AI model runs my agents?

Lindy does, on its Pro plan and above. That mirrors Relevance AI's multi-model support, where you can also pick the underlying model per agent.
