Opencode vs VulnFeed

Opencode and VulnFeed are both cli coding agents tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Opencode

OpenCode is an open-source coding agent that runs in your terminal, a desktop app, or an IDE extension, connecting to 75+ LLM providers including local models. You can spin up multiple agents on the same project in parallel, share debug sessions via a link, and log in with your existing GitHub Copilot or ChatGPT Plus credentials rather than paying again. The no-data-storage architecture makes it viable in privacy-sensitive environments where cloud-only tools are ruled out. The ceiling shows up when you need validated, consistent model performance out of the box — that lives behind the paid Zen add-on, not in the free tier.

VulnFeed

VulnFeed is an MCP server that reads your lockfile directly, cross-references NVD and GitHub Advisories against only the packages you ship, and surfaces results ranked by EPSS — the exploit probability score that separates CVEs attackers are actually using from the ones sitting dormant for years. It runs locally via a single uvx command and feeds results into Claude Code, Cursor, VS Code, or Windsurf. The free tier caps at 10 scans per day and one monitored project; teams that scan frequently or monitor multiple repos will hit that ceiling fast. At that point, the choice is a paid upgrade or a full migration to something like Snyk, which adds code-level remediation context VulnFeed does not provide.

Pros	Connects to 75+ LLM providers including local models, so switching from a cloud API to an on-premise model when data policy demands it is a configuration change rather than a migration. Reuses existing GitHub Copilot or ChatGPT Plus/Pro subscriptions, which means teams already paying for those services get OpenCode's agent layer without an additional per-seat cost. Multi-session parallel agents on the same project, so a developer running a refactor and a test-generation task simultaneously does not queue one behind the other. No code or context stored by the vendor, which means the tool can be deployed in privacy-sensitive or regulated environments where most cloud coding assistants are disqualified at the security review. Session sharing via link lets a developer hand a debug session to a colleague or reviewer without screen-sharing or copy-pasting context — the full session state travels with the URL.	Reads your actual lockfile rather than scanning the full language ecosystem, which means you see only CVEs that affect packages you ship — not hundreds of irrelevant hits from packages you never installed. EPSS scoring surfaces CVEs by real-world exploit probability alongside severity, so you patch the vulnerability attackers are using instead of the one with the highest CVSS number that has sat unexercised for three years. Returns the exact upgrade version per package rather than stopping at 'you are vulnerable,' which means the fix is actionable inside the same conversation with your AI client. Continuous monitoring indexes new CVEs shortly after publication, so a vulnerability disclosed overnight appears in results at your next morning session rather than at your next scheduled scan. Flat-rate paid tier is not per-seat or per-repo, which means a team adding a second developer or a third project does not trigger a pricing jump.
Cons	Model quality and consistency across the free tier's 75+ providers is unvalidated — teams that need reliable agent output without running their own benchmarks hit this wall on the first serious project, at which point they are paying for the Zen add-on or sourcing their own curated model list. The desktop app is in beta on all three platforms; production teams that need a stable, non-beta GUI for daily driver use are back to the terminal interface or the IDE extension until the desktop release matures — the beta label is not a soft warning when a broken update interrupts a sprint. There is no built-in team management, access control, or audit logging described in the vendor's page — organizations that need to track which agents ran what prompts on which codebase for compliance purposes will find those controls absent and move to an enterprise-tier coding platform that ships them by default.	The free tier caps at 10 scans per day and one monitored project — a developer running scans across multiple services or triggering scans on file save will exhaust the daily quota before noon, at which point scanning stops until the counter resets. VulnFeed identifies vulnerable versions and recommends upgrade targets but provides no code-level remediation: no PR generation, no inline diff, no analysis of whether your specific call path reaches the vulnerable function. Teams that need that layer move to Snyk or Socket, both of which offer it — at significantly higher per-developer cost. The tool set covers scanning, CVE lookup, monitoring, and alerts, but there is no policy enforcement layer. Teams that need to fail a build when a CRITICAL CVE with high EPSS is introduced have to wire that logic themselves outside VulnFeed.

Bottom line

Opencode is open source; only VulnFeed exposes a public API. Choose based on which difference matters most for your workflow.
