AgentOps 2.0 is an observability platform purpose-built for multi-agent AI systems, offering session replays, per-node cost attribution, and LLM call tracing. It ships with native integrations for CrewAI, LangGraph, and AutoGen, letting teams debug and monitor complex agent workflows without building custom instrumentation. The rebuilt dashboard surfaces where agents fail, how much they cost, and what calls they made — in a single view.

devnexus creates a shared persistent memory system for AI coding agents working across multiple repositories and sessions. It spins up an Obsidian-based knowledge vault that gets synced via git every ~60 seconds, allowing multiple agents (Claude Code, Cursor, Windsurf, OpenAI Codex) to share architectural decisions, API contracts, data schemas, and cross-repo code graphs — with proper version history. The core problem it solves is "agent amnesia" on teams where multiple developers use different AI tools. Each agent starts every session fresh, unaware of decisions made by the agent next door. devnexus gives them all a common memory store that persists across sessions and codebases. Created April 14, 2026, it's early-stage but addresses a pain point that becomes more acute as teams scale up AI-assisted development. The Obsidian format is a clever choice: the vault is human-readable, searchable with standard tools, and works as a documentation layer even without the AI integration. Git sync means there's a full audit trail of what the agents "knew" at any given time — useful for debugging why an agent made a surprising architectural choice.
Reviewer scorecard
“The primitive here is runtime telemetry for directed agent graphs — think distributed tracing but the spans are LLM calls and tool invocations instead of HTTP requests. The DX bet is SDK-first with framework decorators, which is the right call: you instrument once and the dashboard assembles the session replay automatically. The moment of truth is whether the first `pip install agentops` and two lines of init code actually surfaces a useful trace — if it does, this survives the 10-minute test. What earns the ship is that cost attribution per agent node is a problem I have actually had and couldn't solve cleanly with LangSmith; the skip risk is if the CrewAI/LangGraph integrations are thin shims that miss nested calls.”
“Agent amnesia is a real tax on multi-engineer teams using AI tools. devnexus's approach of using Obsidian + git means the memory is portable, auditable, and doesn't depend on any specific AI provider's memory feature. It's rough around the edges but the concept is sound and I'd build on top of it today.”
“Category is LLM observability, direct competitors are LangSmith, Langfuse, and Helicone — all of which already do call tracing and cost tracking. AgentOps 2.0's specific claim is multi-agent topology awareness: not just 'here are your calls' but 'here is which agent node made which call and what it cost relative to the others.' That's a real gap LangSmith partially fills but makes you work for. The scenario where this breaks is any team running a heterogeneous stack — one CrewAI subgraph calling a custom agent built outside the supported frameworks — because those nodes will be invisible in the replay. What kills this in 12 months: LangSmith ships native multi-agent topology views, which is squarely on their roadmap, and AgentOps' differentiation collapses unless they've built deep integrations that are painful to replicate.”
“This is a four-day-old project solving a genuinely hard problem in the simplest possible way — which means it'll break in interesting edge cases immediately. Obsidian vault conflicts under git are a known pain point, and 60-second sync cycles could create race conditions on busy teams. Wait for it to survive contact with a real multi-engineer setup.”
“The buyer here is an AI engineering team lead whose budget comes from platform or infrastructure, and they're comparing AgentOps to LangSmith — which they may already be paying for. The pricing architecture looks reasonable on paper but the problem is the moat: framework integrations with CrewAI, LangGraph, and AutoGen are open-source collaborations any competitor can replicate in a sprint, and there's no proprietary data layer or network effect accumulating here. What happens when Anthropic or OpenAI ships native multi-agent tracing in their APIs — which is a plausible 18-month timeline — is that the entire observability layer gets commoditized from below. The business survives only if they can expand into alerting, evals, or replay-based fine-tuning before the platform players arrive, and I see no evidence that's the roadmap.”
“The job-to-be-done is unambiguous: 'debug why my multi-agent workflow failed and how much it cost per agent' — no 'and' required, which is a good sign. Onboarding reportedly lands in two lines of instrumentation code before value, which is the right answer for a developer tool; the test is whether the session replay loads within the first run or requires configuring a pipeline first. The product earns a ship because it has a genuine opinion — agent topology as the primary organizing unit, not individual LLM calls — and that opinion matches how teams actually think about debugging CrewAI workflows. The gap to watch: if evals and regression testing aren't in the product, teams will still need a second tool for that loop, and dual-wielding observability plus evals is a friction point that a more complete competitor will exploit.”
“Shared agent memory is the missing coordination primitive for AI-assisted software teams. devnexus is a minimal implementation of an idea that will eventually be built into every enterprise AI coding platform. Getting ahead of that curve now — even with rough tooling — gives teams a learning advantage.”
“For design systems and component libraries shared across repos, the idea is compelling — agents that remember 'we use this button component, not that one' would save a lot of correction cycles. But until this is more than a four-day-old script, I'd treat it as inspiration rather than infrastructure.”
