Shortlist
Closest alternatives to IrisAgent
The ones people open most here come first, then the closest matches. How we rank
- 01
VeraDialVerified
AI receptionist and verified US/Canadian business line that answers calls and texts and places outbound calls.
From $14.99/monthWhy it's on this listSeat model · YesSeats are not charged for but they are capped: the owner plus one teammate on Plus and up to three on Business, with each teammate getting their own login and assigned lines.Source ↗
Where it improves on IrisAgent
- +Data residency · YesStorage and processing sit in the United States, Oregon specifically, with non-US customers consenting to the transfer; sub-processors may hold data in their own regions.Source ↗
Trade-offs against IrisAgent
- −Done-for-you service · NoYou run the software yourself: the vendor explicitly removes the onboarding call and sales demo, and setup is a self-serve number pick plus a website URL, though the Business tier suggests a pre-purchase scoping conversation.Source ↗
- −Claude · NoClaude is supported only as a client that reads your account through the MCP connector; the vendor's own complete list of voice providers for AI calls does not include Anthropic, so Claude does not drive the conversations.Source ↗
- −Self-hosted · NoEverything runs in the vendor's own single-region stack — Supabase in US-West-2 plus Twilio for carriage — and no bring-your-own-infrastructure option is offered on any tier.Source ↗
- 02
KalyvoxVerified
AI phone receptionist that answers inbound calls, qualifies them, transfers or books appointments.
From $95/monthWhy it's on this listAgent permissions · YesWhat the assistant may do is bounded by configuration: call reasons, questions, transfer rules and business information you enter, and the vendor publishes deliberate limits including refusing to answer outside that scope or to place outbound calls.Source ↗
Where it improves on IrisAgent
- +Seat model · YesSeats are the main plan differentiator with a hard ceiling on the lower tiers: one user on Solo, up to five on Pro, unlimited on Business, and the seat count does not change the per-minute usage rate.Source ↗
- +Getting out · YesData comes out in CSV from the dashboard and in a structured JSON/CSV portability request, deletion is available on request, and there is nothing to forfeit on exit because usage is billed after the fact with no prepaid minute bundle.Source ↗
Trade-offs against IrisAgent
- −GPT · PartlyThe only model-vendor disclosure anywhere on the site is a sub-processor entry naming OpenAI for voice processing and transcription; there is no plan row, docs page or settings screen that offers GPT as a selectable model, so this is a supply-chain fact rather than a supported-model claim.Source ↗
- −Model choice · NoThe agent-configuration guide enumerates exactly what a customer may change about the assistant's identity — name, voice and response style — and a model or provider choice is not among them anywhere in the dashboard documentation.Source ↗
- −Self-hosted · NoKalyvox is delivered only as a hosted service: the privacy policy places the database, telephony and payments with named sub-processors on AWS, Twilio and Stripe, and no self-hosted or bring-your-own-infrastructure option appears on any plan or docs page.Source ↗
- 03
MixdeskVerified
Omnichannel customer engagement platform with AI Agents for support, sales and lead qualification.
From FreeWhy it's on this listAdmin controls · YesAdministrators configure roles and per-role permissions, assign groups, and set a data scope of self only, partial or all, plus a conversation capacity per member.Source ↗
Where it improves on IrisAgent
- +Audit log · YesSettings carries an operation log of security-relevant member actions with time, actor, IP address and login device, although filtering reaches back only three months.Source ↗
Trade-offs against IrisAgent
- −Done-for-you service · NoYou run the software yourself on a subscription; the vendor sells plans and provides onboarding help on higher tiers rather than operating agents for you.Source ↗
- −Runs autonomously · PartlyAI Agents reply to customers around the clock without a person present, but they only act once assigned through an automation workflow and the vendor tells you to configure a fallback and human handoff.Source ↗
- −API access · PartlyA documented REST API returns conversations and contacts and can send Telegram messages, but the plan table and pricing notes place webhooks and API access on the quote-only Expert tier.Source ↗
- 04
VoiceFleetVerified
Inbound AI phone receptionist for small businesses: answers calls, captures bookings, escalates urgent callers.
From €99/month (about $111)Trade-offs against IrisAgent
- −Model choice · NoThe buyer picks a plan, not a model: the stack is chosen and may be replaced by the vendor under the terms, and no model-selection control is published on any tier.Source ↗
- −In a browser · PartlyA hosted dashboard is where you configure and review calls, but the analytics dashboard is gated to Growth and Pro and multi-location management to Pro only, so the entry tier gets a thinner web surface.Source ↗
- −Self-hosted · NoIt is a hosted telephony service: the vendor provisions the numbers, hosts the application on Vercel and Supabase and routes calls through its own providers, with regional deployment the only infrastructure choice offered.Source ↗
- 05
Cresta
Enterprise contact-centre platform with autonomous voice and digital AI agents plus real-time human agent assist.
Why it's on this listMulti-agent · YesAgents are built as a decentralised network of specialised subAgents, each with its own prompts, knowledge, tools and guardrails, collaborating on one conversation.Source ↗
Where it improves on IrisAgent
- +Seat model · PartlyAgent count is one of the quoted pricing inputs and the vendor's stated fit starts around 50 to 100-plus care agents, which works as a practical floor, but no per-seat rate or contractual seat minimum is published.Source ↗
- +Admin controls · YesAdmins constrain agents at build time through escalation policies, compliance boundaries and a pre-built or custom guardrail library, with supervisory models enforcing policy in parallel and role-based access control for platform users.Source ↗
Trade-offs against IrisAgent
- −Claude · PartlyAnthropic is named as a sub-processor supplying natural-language APIs, which is the closest Cresta comes to confirming Claude in its stack; buyers are never offered a named model to select.Source ↗
- −GPT · PartlyOpenAI and Microsoft are named sub-processors supplying natural-language APIs; model choice per task is not published.Source ↗
- −Model choice · NoCresta composes and fine-tunes the model stack itself and describes swapping in best-of-breed models as its own work; nothing on the site, docs or terms offers a model picker or bring-your-own-model path, though Opera exposes fine-tuning.Source ↗
- 06
Sierra
Enterprise platform for customer-service AI agents across voice, chat, email and messaging, priced by outcome.
Why it's on this listAgent permissions · YesAutonomy is configurable per workflow: you set goals and guardrails and name the steps that require human sign-off before the agent proceeds.Source ↗
Where it improves on IrisAgent
- +Admin controls · YesAdministrators constrain the agent through goals, guardrails, topic filters and human sign-off points defined before anything reaches customers.Source ↗
Trade-offs against IrisAgent
- −Claude · PartlyAnthropic is a named AI-services subprocessor, so Claude is in the mix, but Sierra routes models itself and never exposes a Claude selector.Source ↗
- −GPT · PartlyOpenAI is listed as an AI-services subprocessor, so GPT models are used under the hood, chosen by Sierra's router rather than by the buyer.Source ↗
- −Model choice · NoModel selection belongs to Sierra: it routes each turn to what it judges optimal and swaps providers on outages, with no published customer model choice.Source ↗
- 07
AiZipZapVerified
Customer intake agent that turns each request into a job brief, missing questions and a reply draft.
From FreeTrade-offs against IrisAgent
- −Runs autonomously · PartlyCollection, saving, drafting and notification run without a human, but the vendor stops deliberately at the draft: the owner reviews, edits and sends every reply themselves.Source ↗
- −Multi-agent · NoOne drafting pass per request is described throughout; the vendor's concurrency statement describes shared generation capacity, not agents coordinating on a task.Source ↗
- −Agent permissions · NoThe agent has no permissions to spend: the vendor lists inbox access, reply sending, code execution and business-system access as things it cannot do at all.Source ↗
- 08
Ada
Agentic customer experience platform running AI support agents across voice, messaging and email.
Why it's on this listSeat model · PartlyDashboard access is managed as named team members with roles, but the commercial meter is conversations rather than seats and no seat count, floor or ceiling is published anywhere on the site.Source ↗
Where it improves on IrisAgent
- +Admin controls · YesAdmins constrain the agent on two axes: role-based dashboard permissions across Owner, Admin, Agent and Read Only, and tool-level activation where discovered MCP tools stay off until explicitly enabled.Source ↗
- +Audit log · YesA searchable audit log records who changed what, when and through which interface, covering dashboard, API, MCP, import and export, and exports to CSV with a 10,000-row cap per view.Source ↗
Trade-offs against IrisAgent
- −Model choice · NoAda chooses the models: it benchmarks a curated portfolio on accuracy, safety, latency and cost and promotes versions through its own evaluation pipeline, so model selection is the vendor's decision rather than a customer setting.Source ↗
- −Self-hosted · NoHosted-only: Ada states all of its infrastructure runs in its own AWS accounts, and the Trust Center risk profile records hosting as a major cloud provider with no on-premise option.Source ↗
- −Free tier · NoThere is no self-serve entry at all: the pricing route resolves to the demo form and the only documented way in is a booked expert session leading to an enterprise agreement.Source ↗
- 09
Fin
Intercom's customer agent that resolves support conversations across chat, email, voice and social channels.
From $0.99/outcomeWhy it's on this listAgent permissions · YesThe buyer sets the boundary: Procedures apply business rules and can require approvals, data access can be restricted to named fields, and Fin escalates rather than answering when confidence thresholds fail.Source ↗
Where it improves on IrisAgent
- +Seat model · PartlyFin itself carries no seat cost and the vendor states teammates are unlimited, but the floor is a 50-outcome monthly minimum, and pairing Fin with the Intercom helpdesk adds a per-seat charge for Full seats.Source ↗
- +Admin controls · YesAn administrator constrains the agent directly — restricting which fields Fin may read, renaming internal values, controlling integration permissions through OAuth, and masking card numbers automatically.Source ↗
Trade-offs against IrisAgent
- −Claude · PartlyAnthropic is one of the providers Fin falls back to for resilience, but the answer model is Intercom's own Apex and the buyer is not offered a model picker, so Claude is under the hood rather than selectable.Source ↗
- −GPT · PartlyOpenAI models are part of the same automatic failover pool as Anthropic and Google, so GPT is used by the platform but is not a model the customer chooses or configures on any tier.Source ↗
- −Open models · NoThe enumerated provider list is OpenAI, Anthropic, Google and Intercom's own models; no open-weight option is offered.Source ↗
What to watch for
- CrestaFull-platform pricing (AI Agent, Conversation Intelligence, Knowledge Agent) is not published, only the narrower Agent Assist SKU has any public price.
- SierraNo public sign-up, pricing page or self-serve API, access is via an enterprise sales engagement.
- AdaEnterprise, sales-led only. No self-serve signup, no public pricing and no free trial.
- FinWhat counts as a billable "resolution" includes soft outcomes (customer stops replying), which can inflate spend relative to true resolutions.
