What counts as Developer Tools

Developer tools covers the platforms, APIs and runtimes engineers reach for first, and the companies trying to remove a step from how software gets built and shipped. On this hub that means communications and messaging APIs, AI-driven testing, no-code and low-code builders, localisation, integration between companies, and the data infrastructure underneath.

Removing a step

Every company on this hub can be described by what it deletes from an engineer's week. Read that way, the hub sorts itself.

Testing was the first thing AI took

Two companies here attack the same bottleneck from different ends. Sapient.ai writes the unit tests, across Java, Scala, Kotlin and Apex. Launchable does not write any tests at all - it uses machine learning to work out which of the existing ones actually need to run, which shortens the wait rather than the suite.

Localisation, done properly

Lingo.dev put 4.2 million dollars into applied AI research for one problem, and the framing is the interesting part: translating software is a code comprehension problem, not a string translation problem. That is what makes 83 languages plausible rather than 8.

The plumbing nobody wants to build

D7 Networks covers SMS, WhatsApp, Viber, number lookup and OTP verification through one API. Voximplant does the same for voice. ScraperAPI handles the proxies, browsers and CAPTCHAs that stand between a developer and a page's HTML, and IPRoyal supplies the proxy layer beneath work like that.

None of these are exciting. All of them exist because building the same thing in-house takes a quarter.

Building without engineers

Momen is the most ambitious of the no-code entries, covering backend logic rather than only interfaces. 10Web automates WordPress for agencies running many sites, and FlowFuse brings Node-RED - long a favourite in industrial automation - into enterprise settings with AI integration on top.

The awkward problems

Exalate works on something most integration vendors avoid: syncing issue trackers across organisational boundaries, where neither side controls the other's system. It has done it bootstrapped, with more than 60 people across seven countries.

Ellipsis Drive picks a similarly unfashionable problem - making satellite, drone and thermal imagery interoperable enough to share at all.

Frequently asked questions

What does the Developer Tools hub cover?

Infrastructure and tooling engineers adopt directly - communications APIs, testing, no-code and low-code builders, localisation, cross-company integration, proxy and scraping infrastructure, and specialised data handling.

What are the AI-native tools here doing?

Removing repetitive engineering work rather than writing features. Sapient.ai generates unit tests across several JVM languages and Apex, Launchable uses machine learning to decide which tests actually need to run, and Lingo.dev translates software into 83 languages by understanding the code around the strings.

Is anyone working on localisation seriously?

Lingo.dev is the main one, and it invested 4.2 million dollars in applied AI research to do it. Its claim is deep code comprehension rather than string replacement, which is what makes translating into 83 languages tractable.

Which of these are aimed at non-developers?

Momen is a no-code full-stack builder covering backend logic for non-technical creators, 10Web automates WordPress hosting and building, and Bonboarding lets teams create interactive product onboarding without engineering time.

Are there any bootstrapped companies here?

Exalate is the notable one - a completely bootstrapped integration company with more than 60 people across over seven countries, working on a genuinely awkward problem: keeping issue trackers in sync between separate companies.
