CrabTrap is an open-source HTTP/HTTPS proxy built by Brex's engineering team that sits between AI agents and the external internet, evaluating every outbound request against configurable security policies before it reaches any third-party API. It uses a two-tier evaluation system: fast deterministic static rules handle the obvious cases (block this domain, require this header), while an LLM-as-a-judge handles ambiguous requests that need semantic understanding — like determining whether a request to send an email is within scope of the current task. Built in Go with a TypeScript frontend, CrabTrap ships with a PostgreSQL-backed audit log and a web UI for policy management. It supports MITM inspection of HTTPS traffic, request/response logging, and policy versioning — making it suitable for production agentic systems where compliance or security teams need a paper trail. Version 0.0.1 was released April 17, 2026 and is MIT licensed. The problem it solves is real: as AI agents gain more autonomy and access to external APIs, the attack surface grows. A compromised or misbehaving agent that can freely call any URL is a significant risk. CrabTrap gives engineering teams a single chokepoint to enforce least-privilege access — something that's been missing from most agentic frameworks that assume a trusted execution environment.

SmolVLM2-2B
2B-parameter vision-language model that runs on your device, not theirs

SmolVLM2-2B is a two-billion-parameter vision-language model from Hugging Face designed for on-device and edge deployment, capable of OCR, document understanding, and image-to-text tasks without a cloud round-trip. Weights, quantized variants (GGUF, MLX, int4/int8), and an Inference API demo are available immediately on the Hugging Face Hub. It benchmarks ahead of similarly-sized VLMs on OCR and document tasks, making it a practical primitive for privacy-sensitive or latency-critical pipelines.
Reviewer scorecard
“This fills a gap that every production agentic system needs but almost no one has solved yet. The two-tier policy engine — static rules for speed, LLM for ambiguity — is the right architecture. The fact that Brex built and open-sourced this suggests they've already battle-tested it against real agent deployments.”
“The primitive is clean: a quantized VLM you can run locally, with weights in every format that matters — GGUF for llama.cpp, MLX for Apple Silicon, int4/int8 for edge hardware — no 6-env-var setup before hello-world. The DX bet is 'get out of the way and give developers the weights,' which is exactly the right call for a model release; the Inference API demo lets you sanity-check outputs before committing. Weekend-alternative test: you cannot replicate a competitive 2B VLM in a weekend, and Hugging Face's OCR benchmark lead at this parameter count is a real technical decision, not marketing copy. The specific thing that earns the ship: Apache 2.0 license plus quantized variants on day one means zero friction from experimentation to production.”
“v0.0.1 with 126 GitHub stars is a weekend project right now, not infrastructure you should bet your production agents on. The LLM-as-a-judge for policy evaluation is also expensive and introduces its own latency — you're adding an AI call to evaluate every AI agent call. The operational complexity of running MITM HTTPS inspection in production is non-trivial.”
“Direct competitors are Moondream2, MiniCPM-V 2.0, and PaliGemma 3B — SmolVLM2-2B is not alone in this weight class, and 'outperforms on benchmarks' is a claim authored by the team shipping the model. That said, the benchmark suite (DocVQA, TextVQA, OCRBench) is standard enough that gaming it would be obvious to anyone reproducing results, and the quantized variants ship simultaneously rather than as a promised future update, which is a trust signal. The scenario where this breaks: complex multi-image reasoning or any task requiring world knowledge beyond visual grounding — 2B parameters are 2B parameters. What kills this in 12 months is not a competitor but the model providers themselves: Google and Apple are both actively shrinking on-device VLMs, and when Gemma Nano gets vision parity at 1B, this specific checkpoint becomes archival. Ships now because the release discipline is real.”
“Agent security tooling is where network security tooling was in the early 2000s — primitive, fragmented, and urgently needed. CrabTrap is an early bet on a category that will be worth billions once enterprises start mandating audit trails for agentic systems. Brex building this in-house and open-sourcing it is a strong signal of what production agent operators actually need.”
“The thesis this model bets on: by 2027, inference moving to the edge is not a feature preference but a regulatory and latency necessity — GDPR enforcement on cloud OCR, sub-100ms UX requirements on mobile, and air-gapped enterprise deployments all converge on 'the model must be local.' SmolVLM2-2B is early-to-on-time on the VLM miniaturization trend; distillation techniques have been compressing vision encoders faster than text LLMs, and the 2B sweet spot is exactly where a MacBook Pro or a Snapdragon 8 Gen 3 runs without thermal throttling. The second-order effect nobody is talking about: when document OCR and receipt parsing run entirely on-device, the SaaS middleware layer — the Mathpix tier, the Rossum tier — loses its technical moat overnight. The dependency that has to hold: quantization quality must not degrade on the real-world document variety that enterprise workflows actually see, which the benchmarks don't fully cover.”
“This is deeply in the DevOps/infrastructure lane — not something a creator or designer would ever touch directly. But if the tools you use to generate content are backed by CrabTrap-style security, you'd want that. For now, it's a ship for the engineers who configure your AI stack, a skip for everyone else.”
“The buyer here is a developer who integrates this into a product, and the pricing is free — Apache 2.0, open weights, no meter running. That's not a business, it's a distribution strategy for Hugging Face's Hub and Inference API, and it works brilliantly for Hugging Face specifically, but there is no standalone business to evaluate. If you're building on top of SmolVLM2-2B, the moat question is brutal: your differentiation cannot be the model because the model is free and anyone can fine-tune it. The specific business problem is that 'we run this VLM on your data on-device' is a real value proposition, but SmolVLM2-2B commoditizes the hardest technical piece of that value prop on day one, which is great for end users and terrible for anyone who was planning to charge for on-device VLM inference. Ships as a technical artifact, skips as a business foundation.”
