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.

Mistral Large 3
256K context, native function calling, open weights — Mistral's best yet

Mistral Large 3 is Mistral AI's most capable frontier model, featuring a 256K-token context window, native function calling, and multilingual support across 30 languages. Model weights are available on Hugging Face under a research license, making it accessible for self-hosted deployments and fine-tuning. It targets developers and enterprises needing a powerful, partially open alternative to closed frontier models.
Reviewer scorecard
“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 a frontier-class language model with native tool-use baked at the architecture level — not prompt-engineered function calling bolted on post-hoc — and a 256K context window that actually changes what you can fit in a single inference call. The DX bet is weights-on-HuggingFace plus a clean API on la Plateforme, which means you can prototype against the API and self-host when your legal team or latency budget demands it. That dual-path is genuinely rare at this capability tier. The weekend-alternative test fails here — you cannot replicate a model with this context length and multilingual quality with three API calls and a Lambda, so the ship is earned on technical substance rather than positioning.”
“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.”
“Direct competitors are GPT-4o, Claude Sonnet 3.5, and Gemini 1.5 Pro — all closed, all at roughly similar capability tiers. Mistral's actual differentiation is the research-licensed open weights, which matters enormously for regulated industries and self-hosters, and native function calling that doesn't degrade into hallucinated JSON like older approaches did. The scenario where this breaks is fine-tuning at scale: the research license restricts commercial derivative models, so anyone building a product on top of fine-tuned weights hits a wall fast. What kills this in 12 months isn't a competitor — it's Mistral's own licensing inconsistency; if they keep alternating between open and restricted licenses, enterprise buyers will stop trusting the roadmap and default to closed APIs with predictable terms.”
“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 Mistral is betting on: by 2027, regulated industries and sovereignty-conscious enterprises will refuse to run workloads on closed US-hyperscaler models, and a capable European model with accessible weights becomes infrastructure — not just an alternative. That bet has real dependencies: EU AI Act compliance pressure must intensify, self-hosting costs must keep falling with hardware improvements, and Mistral must not get acqui-hired or lose the open-weights commitment to investor pressure. The second-order effect that matters most here is not Mistral winning — it's that open-weights frontier models set a capability floor that forces closed providers to compete on more than raw benchmark numbers. Mistral is on-time to the open-weights sovereignty trend, not early, which means execution discipline now determines whether they're infrastructure or a footnote.”
“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 a platform engineering team or an AI-product company whose legal or infosec team has blocked OpenAI and Anthropic API usage — and that buyer pool is larger than most people admit, especially in European financial services and healthcare. The pricing architecture is pay-per-token on the hosted API plus free weights for self-hosting, which aligns with value delivered for API users but leaves self-hosters as goodwill rather than revenue. The moat is genuinely thin: it's European provenance, partial openness, and benchmark competitiveness — none of which are durable alone. The business survives a 10x model price drop because their cost structure moves with it, but it does not survive a world where Meta releases Llama 5 at this capability level under a fully commercial license, which is exactly what the trend line suggests is coming.”
