Gstack Meeting Agents vs Viberia: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Gstack Meeting Agents and Viberia — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Gstack Meeting Agents
AgentCall
Open-source voice agents — CEO, YC partner, QA lead and more — that join your Google Meet, critique your screen, and drop notes in chat.
Key features
- Specialist Personas: Multiple pre-built AI specialists (CEO, CSO, QA lead, YC partner, designer, and more) join meetings in-persona.
- Google Meet Integration: Agents join real Google Meet calls as 3D-avatar participants alongside humans.
- In-meeting Critique: Agents watch your shared screen and critique it out loud, taking turns like real participants.
- Structured Chat Notes: Each persona drops written notes and scores in the meeting chat so feedback is captured, not just spoken.
- Local Brain: Uses your own local coding-agent session (Claude Code, Cursor, Codex) so audio and files stay on your machine.
- MIT-licensed: The platform and personas are open source under MIT license.
- AgentCall Demo: Built on the AgentCall API that lets any agent take a seat in a meeting, so custom personas are possible.
Best for
- YC Interview Prep: Practice pitching to a YC-partner persona that opens with the questions real partners ask.
- Product & Design Review: Get a designer persona to score a UI or landing page in real time.
- Startup Feedback Sessions: Simulate an exec team (CEO, CSO, QA) reviewing a demo before you show real stakeholders.
- Async Meeting Notes: Use the specialist chat notes as structured meeting minutes without a human notetaker.
- Custom Agents in Meetings: Build your own persona on top of AgentCall to join calls with domain-specific expertise.
Viberia
Viberia (get-viberia)
Desktop mission control to visually orchestrate and run multiple coding AI agents locally with provider-agnostic support.
Key features
- Visual Agent Orchestration: Presents agents as units on a strategy-style map so you can see each agent's state, progress, and relationships at a glance, improving oversight and coordination.
- Multi-Provider Support: Connects to Claude, ChatGPT, Gemini and any OpenAI-compatible provider, allowing you to bring your own API keys or reuse existing subscriptions for model execution.
- Local-First Privacy: Runs entirely on the user's machine with no Viberia servers involved, ensuring code, logs and conversations remain private and do not leave the device.
- Team Coordination & Automation: Enables agents to form teams, delegate subtasks, pass results between agents, and coordinate workflows automatically to complete complex development tasks.
- Conversation & Tool Drilldown: Lets users open and inspect agent conversations, view tool usage and results, and trace how an agent reached a decision or produced code.
- Cross-Platform Desktop Builds: Distributes native installers for macOS (Apple Silicon and Intel) and Windows (x64 and ARM64) for straightforward local installation.
- Bring-Your-Keys Model Integration: Users configure provider credentials locally, so billing and usage remain tied to their model subscriptions rather than Viberia.
- Resilient Tool Connections: Supports integrations and tool connections for agent capabilities (with compatibility notes for provider versions and known issues documented).
- Visual mission-control UI for managing multiple agent teams and viewing agent status
- Multi-provider support: Claude, ChatGPT, Gemini, and OpenAI-compatible providers
- Bring-your-own-keys: use your own API keys or existing subscriptions; provider-agnostic
- Local-first architecture: runs entirely on the user's machine; no Viberia servers
- Agent coordination and automation: teams can coordinate and run workflows automatically
- Conversation drill-down: inspect individual agent conversations and history
- Tool connections support (note: Claude Code 2.1.74-2.1.117 have known HTTP MCP bug; update to 2.1.119+)
- Official releases for Apple Silicon, Intel macOS, Windows x64, and Windows ARM64
- Native installers: .dmg for macOS and .exe for Windows
- Open-source presence and release artifacts hosted on GitHub (get-viberia/viberia-releases)
Best for
- Coordinated Code Generation: Split a large feature into sub-tasks and assign specialized agent teams (e.g., frontend, backend, tests) to generate, integrate and validate code concurrently.
- Automated Debugging Workflows: Launch agents to reproduce bugs, generate test cases, propose fixes, and validate patches, while inspecting agent conversations and tool outputs to audit changes.
- Prototype Development: Rapidly prototype an application by orchestrating agents to scaffold project structure, implement core features, and produce runnable demos with minimal human bottlenecks.
- Local, Private AI Workflows: Teams that require on-device privacy can run conversational and coding agents locally without sending source code or chat logs to third-party servers.
- Multi-Model Experimentation: Evaluate and compare outputs from different providers (Claude, ChatGPT, Gemini) in parallel by assigning equivalent tasks to agents powered by each model.
- Teaching Agent Coordination: Demonstrate multi-agent design patterns and workflows in workshops or internal training by visualizing agent roles, communication, and emergent behaviors.
- Orchestrating multiple coding agents to collaborate on software development tasks
- Prototyping and testing multi-agent workflows locally without sending data to external servers
- Managing provider subscriptions and routing agents to different LLM providers
- Debugging and inspecting agent conversations and tool usage during development
- Running automated agent teams for code generation, testing, and CI-related tasks in a private environment
