Kampala, built by Zatanna AI (YC W26), is a macOS proxy tool that sits between your applications and the internet, intercepts every HTTP/HTTPS request, and automatically reverse-engineers the underlying API. It traces authentication chains — tracking tokens, cookies, and session state — and replays flows on demand, preserving original TLS fingerprints so services can't distinguish API calls from the real app. The key insight is that almost every app that lacks a public API still has a private one — and it's usually more stable than the UI. Kampala targets automation engineers, QA teams, and AI agent builders who need reliable machine-readable access to apps that haven't opened their APIs. Setup is a local MITM cert install; no cloud proxy involved. Currently macOS-only with a Windows waitlist. The team emerged from YC's Winter 2026 batch with backing from Y Combinator. Pricing is in early access, with a free tier planned for solo developers and paid plans for teams building production automations.

OpenAI's Operator API brings autonomous web task completion to enterprise API customers, letting businesses define custom action schemas that constrain and direct what web actions the agent can take. It runs within the customer's own security perimeter, giving enterprises control over data handling and agent behavior. The API is the programmatic layer behind the Operator product that was previously only available as a consumer-facing tool.

This is the tool I've been building in-house at three different companies and never had time to productize properly. The auth chain tracing alone — tracking token refresh flows and session state automatically — would have saved me hundreds of hours. If it works as advertised, it's an instant ship for anyone doing integration work.

The primitive here is clean: a constrained-action web agent you define via JSON schema rather than prompts alone, which is actually the right DX bet — putting the complexity in schema definition rather than natural-language wrangling. The moment of truth is whether custom action schemas are expressive enough to cover real enterprise workflows without becoming a second job to maintain; the fact that they ship with schema validation and perimeter deployment suggests someone thought about production use, not just the demo. What earns the ship is the honest constraint model — rather than 'do anything on the web,' you define the action surface, which is exactly how you'd design this if you were building it yourself and cared about reliability.

Terms of service violations are a real concern here. Most apps explicitly prohibit automated access through their private APIs, and companies like LinkedIn and Instagram have sued over exactly this pattern. The MITM cert requirement also opens a broad attack surface. Wait for a clearer legal stance before building production systems on this.

The direct competitor here is every RPA vendor — UiPath, Automation Anywhere — plus Anthropic's Computer Use API and every browser-automation wrapper that's been rebuilt on top of Playwright in the last 18 months, and none of those have actually solved the brittleness problem at enterprise scale. This breaks the moment a website updates its DOM structure, a CAPTCHA variant appears, or a multi-step workflow has an ambiguous intermediate state — and no custom action schema saves you there. The thing that kills this in 12 months is OpenAI either baking this into their main API products at a fraction of the cost, or enterprises discovering that maintaining action schemas for 40 internal tools is itself a full-time engineering job that defeats the automation value prop.

The long-term story here is about AI agents needing reliable access to every app humans use. We can't wait for every SaaS to ship an official API. Tools like Kampala are how AI agents will integrate with the existing software ecosystem for the next five years, until MCP-style universal interfaces catch up.

The thesis here is falsifiable: within 3 years, enterprises will manage fleets of web agents the way they manage microservices today — with schemas, permissions, and audit logs rather than RPA scripts and macros. The dependency is that web interfaces remain the dominant enterprise integration surface long enough for schema-defined agents to become the standard abstraction, which holds as long as legacy SaaS vendors don't all ship proper APIs (they won't, at least not fast enough). The second-order effect that matters isn't task automation — it's that custom action schemas become the new enterprise integration contract, shifting power from IT middleware vendors toward whoever controls the agent runtime, which right now is OpenAI. This is early on the enterprise-agent-fleet trend line, not on-time, which makes the risk real but the upside asymmetric.

For social media automation and cross-platform content workflows this is a game-changer. Building automations for platforms with limited or expensive APIs has always required fragile browser scraping — having a stable API layer extracted from the real app traffic is a much better foundation.

The buyer is clear — enterprise IT and automation teams pulling from RPA or integration budgets — but the pricing architecture is the problem: 'contact sales' with no public tier means OpenAI is betting enterprises will absorb unknown per-task costs before they've validated reliability, and that bet historically fails for automation tools where ROI is measured in runs-per-day at scale. The moat question is uncomfortable: the defensible position is supposed to be the model quality, but Anthropic ships Computer Use with comparable capability, and the action schema format is not proprietary enough to create switching costs once a team has invested in defining them. What needs to change for this to work as a business is transparent consumption pricing that lets an ops team model their unit economics before signing a contract — without that, sales cycles will be long and churn will be brutal once the first production incident hits.
