Analysis of JIT

Overall verdict

Jit (jit.dev) is a solid, developer-focused security platform that automates and orchestrates application security tooling, making it a strong choice for teams looking to embed security into their development workflows without heavy overhead.

Why this product is good

Provides an automated security orchestration layer that unifies multiple open-source and commercial security scanners (SAST, SCA, secrets detection, IaC scanning, etc.) into a single workflow
Integrates directly into developer environments like GitHub, GitLab, and CI/CD pipelines, reducing context switching
Offers a code-based, GitOps-friendly configuration approach that lets teams define security plans as code
Focuses on developer experience by surfacing actionable findings within pull requests rather than overwhelming teams with noise
Helps teams adopt a 'security as code' and DevSecOps model with minimal manual setup
Can accelerate compliance readiness by mapping controls to recognized frameworks

Recommended for

Startups and scaling engineering teams that want to build security into their SDLC early
DevSecOps teams looking to consolidate and automate multiple security scanning tools
Organizations practicing GitOps and infrastructure-as-code who want security-as-code
Development teams that need actionable security feedback directly in their pull requests and CI/CD pipelines
Companies aiming to improve security posture and compliance readiness without hiring a large dedicated security team

Strands Agents + Langfuse Evaluations
In this project we will build a Python banking assistant agent using Strands Agents and make it observable and continuously evaluated using Langfuse — step by step. - Source: dev.to / about 1 month ago
Best AI Monitoring Tools in 2026: LLM, Agent, and MCP Observability Compared
Langfuse is the open-source standard for LLM observability. It traces every LLM interaction — prompts, completions, latency, token usage, cost — and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / about 2 months ago
What is an LLM evaluation harness? A deep dive into lm-eval-harness
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 2 months ago
How to track LLM costs per customer in production
Gateway or proxy attribution. A reverse proxy in front of the model-provider API records the request, computes the cost, and exposes per-customer breakdowns. Open-source options include Helicone, LiteLLM, Langfuse, and OpenLLMetry. Hosted equivalents serve as the AI cost observability layer for teams that want centralized visibility: LangSmith, Datadog LLM Observability, Arize Phoenix.

Per-user cost attribution for your AI APP
Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline — the metadata.userId pattern is the universal part. - Source: dev.to / 3 months ago
