Duvi vs Replit Agent 3: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Duvi and Replit Agent 3 — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Duvi
Duvi DigiIQ, Inc.
Build voice and chat support agents by describing them in conversation; one configuration answers on your website, WhatsApp and phone line.
Key features
- Conversational Agent Builder: Creating an agent opens a conversation with a builder that writes the system prompt, picks a model and ingests the websites the agent should answer from, so setup is a dialogue rather than a configuration form.
- Unified Omnichannel Configuration: One agent configuration serves website chat, a WhatsApp number and a phone line, with the same knowledge behind every channel so context is not lost when a customer switches.
- Live Knowledge Lookups: The agent checks your connected store as it answers, so stock and catalogue responses reflect what is actually available at that moment rather than a stale snapshot.
- Website Actions: With the customer's instruction the agent operates the on-page controls you allow, completing the task in front of them instead of handing them a link and instructions.
- Grounded Answering: The agent answers from the pages you point it at and says so when the information is not there, rather than guessing.
- Preview Before Launch: Agents are tested in Preview and only go live once the domain is allowed and a snippet is pasted on your site.
- Broad Connector Library: Sign-in level integrations for Shopify, WooCommerce, Wix, Salesforce Commerce Cloud, Stripe, PayPal, Notion, Airtable, Webflow, Linear, monday.com, Sentry, Supabase, Cloudflare and Zapier.
- Team Workspace: Staff query the day's conversations and orders through their own authorized connection, so the answer reflects the order a customer placed moments ago.
Best for
- Ecommerce Support Deflection: A Shopify store answers stock, shipping and returns questions automatically, with the agent reading live catalogue data instead of a static FAQ.
- Lead Capture With Context: An agent takes a caller's email or number and routes it to the team with the whole conversation attached, so nobody asks the customer to repeat themselves.
- Phone Line Replacement: A small team replaces a recorded phone menu with an agent that answers real questions using the same knowledge base as the website chat.
- WhatsApp Commerce: A brand serving customers primarily on WhatsApp runs the same support agent there without maintaining a separate bot.
- Startup Support Coverage: An early-stage team keeps answering customers around the clock while engineers focus on building the product.
- Enterprise Support Augmentation: An established support operation adds agents to an existing stack via connectors rather than replacing its tooling.
Replit Agent 3
Replit
Autonomous coding agent that builds, tests, and fixes apps automatically with long runtimes and workspace integrations.
Key features
- Autonomous App Construction: Builds full applications from project context and instructions, orchestrating multiple development steps (scaffolding, dependency installation, and initial code generation) without continuous human input.
- Automated Testing and Fixing: Runs test suites, detects failing tests or runtime errors, and iteratively applies fixes to source code until tests pass or a defined stopping condition is met.
- Extended Runtime Sessions: Supports long-lived agent runs (advertised up to 200 minutes) to handle multi-step workflows, long-running builds, or extensive debugging sessions that shorter agents cannot complete.
- Tool and Workspace Integrations: Connects with external collaboration tools such as Slack and Notion to post results, receive triggers, and integrate agent activity into team workflows and documentation.
- Sandboxed Code Execution: Leverages Replit's code-exec/eval infrastructure to execute generated Python (and other) code in ephemeral, unprivileged containers for numerical reasoning, testing, and validation.
- Multi-step Orchestration and State Handling: Manages sequential tasks, preserves context across steps, and can coordinate edits, tests, and deployments across a project repository.
- Notification and Reporting: Produces actionable reports and sends notifications to integrated tools or channels about build status, test results, and applied fixes.
- Autonomous build, test, fix, and redeploy loop
- Agent-of-agents: can generate other agents/automations
- Integrations with Slack, Notion and other tools
- Extended runtime (advertised 200min runtime on the product page)
- Metered usage via Replit credits and usage-based billing
- Deployable agents and testing workflows
- Automatic build, test, and fix cycles for applications
- Extended runtime for agents (advertised 200 minute runtime)
- Higher autonomy compared to prior versions (advertised 10x more autonomous)
- Integrations with external tools and services (examples: Slack, Notion)
- Designed to work with Replit code-exec APIs and ephemeral execution containers
- Optimized for agents to evaluate generated Python code and perform numerical reasoning
Best for
- Automated CI-like Workflows: Continuously run test suites, reproduce failing tests, and automatically propose or apply fixes, reducing manual triage time for developers.
- Bug Triage and Repair: Given a failing test or bug report, reproduce the issue in a sandbox, identify root causes, and generate patches or pull requests that fix the problem.
- Long-running Feature Implementation: Implement multi-step features that require iterative development, testing, and dependency management within a single extended agent run.
- Integration-driven Notifications: Monitor repository activity or CI signals and post detailed updates, diagnostics, and suggested fixes into Slack or Notion for team visibility and tracking.
- Prototype to Deployment: Rapidly scaffold prototypes, run end-to-end tests, and assist in deploying simple apps or demos using Replit's hosting capabilities.
- Interactive Code Evaluation: Execute generated scripts or numerical reasoning code in ephemeral containers to validate outputs and adjust generation strategies based on results.
- Automated feature development and iterative bug-fixing
- Creating autonomous bots or agents for internal workflows
- Automating testing and CI-like workflows for small apps
- Rapid prototyping and deploying small services with integrations
- Team collaboration where agents assist coding and review
- Automated end-to-end app development tasks (build, test, fix) driven by natural-language prompts
- Running longer-running agent tasks such as extended debugging or integration workflows
- Evaluating generated code snippets or numerical reasoning via Replit's code-exec interfaces
- Integrating development workflows with collaboration tools (Slack, Notion) for notifications or orchestration
- Using ephemeral sandboxed containers for safe execution of agent-generated code
