Browser Compatibility
Browser compatibility is the degree to which a product's required features and interactions work across the browsers and devices its audience uses. Set a support policy from audience evidence and test critical workflows against that policy.
What You Will Be Able to Decide
- Explain browser compatibility in product and business terms.
- Apply this decision: Set a support policy from audience evidence and test critical workflows against that policy.
- Recognise this material risk: the product is declared working after testing only the developer's current browser.
- Ask a consultant for evidence rather than reassurance.
A founder is reviewing the browser-facing part of a product with a consultant or coding agent.
Browser compatibility is the degree to which a product's required features and interactions work across the browsers and devices its audience uses.
A consultant can recommend and implement the technical approach. The founder still needs to decide which outcome matters, which risk is acceptable, and what evidence is sufficient.
The Founder Situation
A founder is reviewing the browser-facing part of a product with a consultant or coding agent.
The immediate question is browser compatibility. The technical label matters only because it changes a product decision, a responsibility, or the evidence required before launch.
Technical term
Browser Compatibility
Browser compatibility is the degree to which a product's required features and interactions work across the browsers and devices its audience uses.
Treat it like a clause in a commercial agreement: its value comes from making expectations and consequences clear, not from sounding formal.
What Matters in Practice
Start with the product consequence, then choose the simplest technical treatment that protects it. A longer tool list is not a stronger plan.
For this decision, the useful standard is that the interface remains understandable, accessible, and dependable across realistic devices and data states.
- Make the decision explicit: Set a support policy from audience evidence and test critical workflows against that policy.
- Ask what evidence would show that the chosen approach works.
- Name the person or provider responsible when the approach fails.
- Record the result in the frontend proposal and review notes.
A Proportionate Decision
Set a support policy from audience evidence and test critical workflows against that policy.
The principal risk is that the product is declared working after testing only the developer's current browser. This does not require the most expensive possible solution. It requires the consequence to be understood and the control to match it.
- Describe the user or business outcome that must be protected.
- Identify the most credible failure and its consequence.
- Compare the simplest adequate approach with one realistic alternative.
- Set a review point for when the decision may need to change.
Strong Evidence and Weak Reassurance
Warning Signs
- Nobody can explain how browser compatibility changes a user or business outcome.
- The proposal does not address this risk: the product is declared working after testing only the developer's current browser.
- The only evidence is a successful demonstration of the easiest path.
- The decision has no named owner, boundary, or review point.
- A provider-specific feature is being mistaken for a permanent product requirement.
Questions to Ask a Consultant
- What decision are we making about browser compatibility?
- Which user or business outcome does the recommendation protect?
- How have we reduced or accepted this risk: the product is declared working after testing only the developer's current browser.
- What evidence can I review without relying on the original implementer?
- What is deliberately deferred, and when will it be reconsidered?
- Who owns the accounts, data, documentation, and recovery process?
Key takeaway
Key Takeaway
Browser compatibility is the degree to which a product's required features and interactions work across the browsers and devices its audience uses. The founder's job is to make the consequence explicit; the consultant's job is to recommend and demonstrate a proportionate implementation.
