If you have built an AI chat feature with the Vercel AI SDK, you have used its useChat hook. You give it your messages, and it streams the reply into your UI. You may have seen our post on the custom transport we built for the Vercel AI SDK. It swaps useChat's default transport for Ably AI Transport, adding resumable streams, cross-device and multi-user sync, conversation branching, history compaction, and stop-and-approve controls.

You add a stop button to your AI chat app: a customer support agent, a coding assistant, a research tool the user can steer mid-task. A user clicks it mid-response. The frontend stops rendering. Then you check your backend logs and realize the underlying generation is still running, and you’re still paying for every token. This is not a bug.

You are forty-eight hours into the role. The acquisition has closed. The press release went out. The operating partner has sent a congratulatory message and a list of reporting expectations. And somewhere in a credit agreement you are still reading, there is a covenant reporting deadline. It is in 45 days. It requires auditable numbers from a business you have not yet fully seen, running on systems you do not yet control, with a finance team you have not yet met.

An automation suite that’s losing ground rarely makes it obvious. Coverage numbers look reasonable. Tests are running. The CI pipeline is green more often than not. Meanwhile, the team is quietly working around what isn’t working – rerunning tests until they pass, deferring maintenance, or accepting a regression window that’s wider than it should be. Those workarounds can feel normal. They aren’t.

Most real estate and PropTech product teams know they have too many integrations. What they struggle to answer is a sharper question: which ones actually matter? Surveying customers or tallying feature requests gives an incomplete picture. It conflates noise with signal and produces roadmaps full of integration work that never meaningfully moves retention, revenue, or product adoption.

Flaky tests not only slow your pipeline but also limit how fast your entire organization can move. Learn how AI is finally breaking through it.

Many engineering leads assume game testing happens only near launch, with testers logging bugs in the final months.

The fintech market in 2026 is shifting from growth at all costs to sustainable scale. According to McKinsey’s fintech outlook, investors are prioritizing operational efficiency, AI readiness, and scalable infrastructure over aggressive expansion alone. At the same time, Deloitte’s banking industry outlook highlights major trends shaping fintech platforms, including embedded finance, cloud native banking, compliance automation, and real time payments.

k6 and Apache JMeter are two of the most widely used open source load testing tools, and teams evaluating one almost always end up comparing it to the other. They solve the same problem, simulating traffic against your APIs and websites to find where performance breaks, but they come from different eras and design philosophies, and the right choice depends a lot on who is writing the tests and what you are testing. We run both tools at scale on LoadFocus, so we have no horse in this race.
