## Viktor vs Open source

| Feature | Viktor | Competitor |
| --- | --- | --- |
| Surface | Slack and Microsoft Teams, in the channel where the work is already discussed. | Local or hosted environments, often connected to messaging channels. Managed offerings provide a different operating model from self-hosting. |
| Works for | The whole team. Anyone can tag Viktor; context belongs to the workspace. | Technical users and teams who value control over deployment, models, or configuration. |
| Who owns the job | Reads the request, uses connected tools, produces the deliverable, and reports back in the thread. | Agents can perform tasks, while responsibility for hosting, maintenance, and configuration depends on the deployment. |
| Memory | Shared workspace context. What one person teaches Viktor can help the team. | Local, hosted, or workspace context; storage and sharing are implementation-specific. |
| Tools | 9,800+ integrations, browser access, code execution, and published pages and apps. | Model providers, plugins, gateways, and connectors selected by the operator or managed provider. |
| Price shape | Shared workspace credits from $100/month, without a subscription for each teammate. | Check Open source's current plans for pricing, included usage, and availability. |
| Best for | Ongoing team work across your connected tools. | You want control over models, deployment, and configuration. |
