Agent-QA vs Opencode

Agent-QA and Opencode are both coding assistants 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.

Agent-QA

The tool lets you write test steps in plain language — 'Click on the Create issue icon', 'Verify that the created issue is shown' — and an agent translates those into browser actions at runtime, reading visible labels and screen state instead of fragile CSS selectors. After each run, it builds execution memory: observations about navigation contracts, UI quirks, and previously healed steps, which get injected into future runs so the agent stops rediscovering the same UI patterns. Self-healing means that when a component shifts, the agent iterates through recovery attempts rather than failing immediately. The ceiling appears when test logic branches on conditional application state — the YAML authoring model is built for linear flows, and complex branching sends teams back to scripting.

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.

Attribute	Agent-QA	Opencode
Pricing	Paid	Paid
Free trial	No	No
Open source	Yes	Yes
Has API	Yes	No
Self-hosted option	Yes	Yes
Platforms	Web and mobile (Chromium, mobile drivers)	Terminal, Desktop (beta macOS/Windows/Linux), IDE extension
Pros	Natural language test authoring against visible UI labels rather than DOM selectors, so a component rename or layout shift does not immediately break the test suite the way a hard-coded selector would. Execution memory that accumulates across runs with trust scores and confirmation counts, which means the agent stops wasting run time rediscovering navigation patterns it has already mapped — later assertions stay focused on actual page behavior. Self-healing iteration within a single run — when an action fails, the agent retries with updated screen state observation rather than failing the step immediately, so transient UI delays cause fewer false negatives. Support for custom and open-source LLM models at the infrastructure level, so teams with data-residency requirements or API cost constraints can run inference locally without forking the tool. Open-source codebase with self-hosted deployment option, which means teams are not locked into a vendor's uptime or data pipeline when running tests against internal staging environments.	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.
Cons	The YAML step format is built for linear flows — action, verify, action, verify. Test scenarios that branch based on runtime application state (for example, different assertion paths depending on what a previous step returned from the server) have no native expression in the authoring model. Teams with conditional logic either maintain a parallel scripting layer or restructure tests into multiple flat suites, which defeats the maintenance advantage. Execution memory is only as reliable as the trust scores the agent has accumulated. On a new application or after a major redesign, early runs produce low-confidence observations and the agent behaves closer to a first-run tool — the adaptive advantage appears after repeated runs against a stable-ish UI, not on day one. Teams whose test requirements outgrow linear natural-language flows — particularly those already running Playwright or Cypress suites with custom fixtures, parameterized data, and programmatic assertions — will find agent-qa's authoring model too constrained and switch back to code-first frameworks where branching logic is a function call, not a workaround.	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.

Bottom line

Only Agent-QA exposes a public API. Choose based on which difference matters most for your workflow.
