OpenSEO and bisibility overlap more than they used to, so the choice is now about scope and control rather than about which one has research.
OpenSEO is a broad, agent-first SEO toolkit: keyword research, rank tracking, domain overview, backlinks, site audits, AI visibility, and a Prompt Explorer, driven primarily through MCP and agent skills.
bisibility covers keyword research, backlinks, domain overview, and rank tracking. It adds the operational layer around them: a versioned REST API with SDKs and a CLI, signed webhooks, alerts, audit logs, team roles, per-keyword schedules, provider choice with fallback, spend caps, and a PostgreSQL database you can query directly.

OpenSEO is a better fit when you want site audits, AI visibility, and an agent-first workflow in one product. bisibility is a better fit when rank history is operational data: something you query, automate against, alert on, and control the provider and cost of.
You want site audits and AI visibility, an MIT license, and an MCP-first workflow.
You want research plus a REST API, alerts, team roles, provider choice, spend caps, and your own PostgreSQL data.
The first two are ready-to-use products. DataForSEO is an API you build around.

| SERP provider choice | DataForSEO or SerpApi, with automatic fallback | DataForSEO only | Your own integration |
| Markup on provider data | None; you pay the provider directly | None on self-host; 28% on the hosted plan | None; you are the customer |

| Minimum data spend to start | Self-host: $50 DataForSEO increments, or SerpApi plan | Hosted: $10/mo incl. $10 credits; self-host: $50 DataForSEO increments | $50 DataForSEO top-up increments |
Export your keywords from OpenSEO, then import them into bisibility by CSV or API. Past ranking positions do not move with them. Keep the OpenSEO export if you need the old history.
Scope and control. Both do keyword research, backlinks, domain overview, and rank tracking. OpenSEO adds site audits and AI visibility and is driven mainly through MCP. bisibility adds a REST API, alerts, webhooks, team roles, per-keyword schedules, provider choice with fallback, spend caps, and direct SQL access to your history.
OpenSEO does not document a public REST API. MCP is its documented interface. bisibility provides a REST API, OpenAPI, TypeScript SDK, CLI, and MCP access.
You can move your keyword list by CSV or API. Historical positions do not transfer, so keep the OpenSEO export if you need the old history.
bisibility has team roles, alerts, and schedules for each keyword. OpenSEO's self-hosted multi-user support is still open in issue #87.
AI Overview and LLM visibility tracking is on the roadmap. When it lands, it writes to the same PostgreSQL database you already own, next to your rank history.
Run the app, PostgreSQL database, and scheduled-check worker on your own infrastructure. You operate upgrades, backups, monitoring, and provider secrets.
