// compare //
ContextQA and TestZeus agree on most things. Both are AI-native, both test AI agents, both charge for usage rather than seats. The difference shows up in where Salesforce sits: on their Enterprise plan, or at the centre of ours.

// short version //
Choose ContextQA if
You are validating AI agents across several platforms such as Agentforce, Bedrock, Azure AI Foundry and Snowflake Cortex, and need governance depth: red-team adversarial testing, guardrail probing, PII and compliance scanning, model-drift regression. Their AI agent testing is broad and serious, and no honest comparison pretends otherwise.
Choose TestZeus if
Salesforce is the centre of your quality problem rather than one enterprise app among many, you want Salesforce and Agentforce testing on the plan you actually start on, you want an open-source core your security team can read, and you would rather sign up than schedule a demo.

// cost of coverage //
Same principle. One of us publishes the number.
We agree with ContextQA on the important part. Per-seat licensing is the wrong model for testing, because it quietly discourages the admins, analysts and product people who should be contributing coverage. They charge for usage rather than logins, and so do we.
Where we differ is disclosure. ContextQA declines to publish a price, and gives a reasonable explanation: footprints vary so widely that one number would mislead. That is a fair argument, and it still means you cannot compare anything until you have taken a call.
We publish the rate and let you do the arithmetic yourself.
Unlimited
Users on every plan. QA, Salesforce admins, product managers, developers, release managers and business stakeholders.
Unlimited
Test runs included every month on Team Cloud, with unlimited environments, test creation and reports.
$0.99
Per test run after that. You can work out your bill before you speak to anyone.
There is a second difference worth pricing in. With ContextQA, Salesforce testing and AI agent testing both sit on the Enterprise tier. With TestZeus they are the product, on the plan you start on. If those two things are why you are shopping, check which tier you would actually land on before comparing anything else.

// execution model //
Generated suites, or nothing stored at all
ContextQA points at a flow and writes a production-grade suite covering happy paths, edge cases and failure states, then patches locators within the same run when the DOM shifts. They have executed 18M+ tests and auto-fixed 3M broken ones, which is a real number and a real capability.
The suite is still an artifact. It is generated rather than hand-written, and healed rather than manually repaired, but it exists, it is stored, and it drifts from the application over time.
TestZeus generates nothing to store. You write the intent, in any language:
Feature: Lead conversion
Scenario: Sales rep converts a qualified lead
Given I am logged in as a sales user
When I convert a lead with a qualified status
Then an account, contact and opportunity are created
The agent interprets that on every run against the org as it exists today. There is no suite to heal, because there is no suite.
Be honest with yourself about which you want. A generated, exportable suite is portable and inspectable - ContextQA will export to Playwright, Selenium or Cypress, which is a genuinely good answer to lock-in. Runtime interpretation gives you less to maintain and less to hold.
// getting started //
Sign up, or book a call
Every route into ContextQA runs through a conversation. Starter, Growth and Enterprise all say request a demo, and their recommended path is a scoped pilot run in your environment with their team involved. For a lot of enterprise buyers that is exactly right a guided pilot on a real app beats a trial you abandon after twenty minutes.
TestZeus lets you sign up and start. Connect an org, describe a flow, run it. If you want a person, every plan includes an assigned Forward Deployed Engineer, but nothing is gated behind arranging one.
If your evaluation has to happen this week and you would rather see it fail on your own org before anyone pitches you, that difference matters. If you would rather be walked through it by someone who has done it before, theirs is the better shape.

The closest we come to a tie
Most comparison pages save their strongest claim for this section. We are not going to, because it would not survive five minutes on their site.
ContextQA's AI agent testing is deep. They score response accuracy against a source of truth, probe guardrails for PII disclosure and policy bypass, validate tool calls argument by argument, auto-generate red-team adversarial prompts from your agent's own docs, re-run scenario suites against every model upgrade to catch drift, and scan responses for HIPAA, GDPR and SOC 2 violations. They do it black-box across Agentforce, Bedrock, Azure AI Foundry and Snowflake Cortex. That is a more governance-oriented and broader offering than ours.
Two things still separate us. Theirs is an Enterprise-tier capability; ours is what the product is for, from the plan you start on. And ours is built around Salesforce specifically - multi-turn, multiplayer, multilingual conversation with Agentforce agents including voice, tested the way your customers in each market will actually speak to them.
If your risk is AI governance across a fleet of agents on several platforms, talk to them. If your risk is that your Agentforce deployment breaks for a customer speaking Hindi at 2am, talk to us.

Where we'd point you to ContextQA
Your agents live on more than Salesforce.
Bedrock, Azure AI Foundry, Snowflake Cortex and Intercom Fin as well as Agentforce. If you are running a fleet across platforms, that breadth is the argument and we do not match it.
You need AI governance evidence, not just test results.
Red-team adversarial testing, guardrail probing, model-drift regression and PII scanning against HIPAA, GDPR and SOC 2. If your board is asking who is checking the agents, that is the shape of the answer they want.
You want your tests exportable.
Clean export to Playwright, Selenium, Cypress and WebdriverIO is a genuinely good answer to vendor lock-in. Our answer is an open-source core, which suits a different buyer.
You need mobile or database testing.
ContextQA covers both. We do not.
Procurement wants certifications on the table today.
SOC 2 Type II, ISO 27001 and GDPR compliance, on every plan.
// switching //
Moving from ContextQA
If you are already on ContextQA and it is working, this page is not trying to move you. The teams who switch are usually the ones who signed up for enterprise app testing, found Salesforce and agent testing sitting behind the Enterprise tier, and started wondering whether a Salesforce-first tool would cost less and go deeper.
The evaluation we would suggest: take your Agentforce agent and the five Salesforce flows you care most about, run them in TestZeus for a sprint, and compare depth on those specifically. Everywhere else the two tools will look similar, because they largely are.
VERIFY: confirm what our conversion tooling supports for ContextQA suites, if anything.
INSERT PROOF: a customer who evaluated both, or a Salesforce-specific depth example.

Frequently asked
How is TestZeus different from ContextQA?
Both are AI-native, test AI agents and charge for usage rather than seats. Three differences are real. ContextQA places Salesforce testing and AI agent testing on its Enterprise tier, while for TestZeus they are the core product on every plan. TestZeus has an open-source core; ContextQA is proprietary with code export. And TestZeus lets you sign up and start, while every ContextQA plan begins with a demo request.
