All 22 Codex in Chrome alternatives
Peter Steinberger's open-source personal AI agent that lives inside the messaging apps you already use — WhatsApp, Telegram, Discord, Slack, Signal, iMessage — and can take real actions on your behalf: browse the web, run shell commands, read files, and orchestrate tasks across 50+ integrations. Bring-your-own model: cloud (Anthropic, OpenAI, Google) or fully local through Ollama or LM Studio if you want inference to stay on your hardware. Independent project, explicitly not affiliated with Anthropic, with persistent memory that carries context across sessions.
Anthropic's framework for building production AI agents on top of Claude — with built-in tool use, file system access, code execution, and the same orchestration that powers Claude Code itself. The most direct path for developers who want agent capabilities without rebuilding the harness from scratch, and the official SDK to use when you need to ship agents on Claude in production.
Google's desktop orchestration app for building and running multi-agent pipelines. Version 2.0 adds expanded model support and live workflow monitoring. PH launch 21 May 2026 with 242 votes.
Drop-in memory layer that lets coding agents remember decisions, conventions, and prior fixes across sessions — so Claude Code stops re-discovering the same context every run. PH launch 16 May 2026 with 208 votes.
MCP server from Apideck that exposes 200+ business apps (CRM, accounting, HR, file storage) as a single unified interface for agents. Instead of writing a custom connector per tool, agents call one MCP and Apideck handles the underlying API surfaces. PH launch May 2026 with 145 votes in the rapidly-growing MCP tooling niche.
No-code computer-use agent builder — describe the workflow and Astro, Asteroid's meta-agent, constructs and debugs the agent autonomously, producing reusable scripts you can hand off. Targets messy real-world automation: EHRs, insurance portals, desktop apps, VPN-protected systems. API-first with webhooks, MCPs, SDKs, persistent sessions, and human-in-the-loop checkpoints. PH launch 14 May 2026 with 129 votes.
Agentic business-ops platform pitched as an "AI COO": ingests your tools and metrics, identifies process gaps, and runs cross-functional workflows that would normally need a fractional ops hire. Aimed at founders without an operations layer. PH launch May 2026 with 183 votes — fits Directr's growing agentic-business-ops shelf.
Managed scraping API designed for agent workflows — handles proxies, JS rendering, and CAPTCHA bypass so agents can fetch live web data without owning the infra. PH launch 15 May 2026 with 312 votes.
A macOS notch app that surfaces what your Claude Code and Codex sessions are doing in real time — token usage, permissions, dev server status, and pinned project folders — without leaving your editor. Works across Ghostty, tmux, iTerm, and any terminal flavour. The right utility for anyone running multiple coding agents in parallel and tired of context-switching to check on them.
A security layer for OpenClaw and adjacent agent runtimes — pre-install code analysis to flag dangerous skills, real-time behavioural monitoring through its Watchtower component, and a sub-200ms verification API for production gating. Ships with a Security Companion Agent and full OWASP ASI coverage to catch data exfiltration patterns and unsafe tool calls before they execute. The first credible answer to "how do we let agents run code without giving them the keys to the kingdom."
Schedules recurring AI agent runs with one command and zero infrastructure — no servers, queues, or wrappers required. The plumbing layer for anyone running agents that need to wake up on a schedule rather than only on a user prompt, which covers most production agent use cases once you move past chat.
OpenRouter, but for backend infrastructure rather than models — one API provisions databases, auth, storage, vector search, hosting, Redis, and a dozen other services that agents typically need. Handles lifecycle and billing across all of them, so you stop juggling six dashboards to ship one agent. Early-stage but well-positioned for the moment when "spin up an agent" needs to be one command, not one weekend.
Lets AI agents publish HTML output as a real URL — gated behind SSO so the link is only usable inside your company. Solves the awkward gap between an agent generating something rich and getting it in front of internal users without shipping screenshots or pasting into Slack. PH launch May 2026 with 133 votes.
Real-time visibility into which bots and AI agents hit your site — which pages they read, where they came from, and what human referrals they end up generating from ChatGPT, Claude, and other LLM-backed surfaces. The right tool for the new reality that a lot of your traffic is no longer human and you still need to optimise for it. ~5 minute install, free for most sites, and one of the few products treating LLM referral as a first-class analytics signal.
Open-source browser automation built on Bun rather than Node, with an API designed for AI agent workflows from the ground up. Faster startup and lower memory overhead than Puppeteer or Playwright when spinning up disposable browser sessions for agents to drive — useful for any developer building autonomous web tasks at scale.
NVIDIA's open-source stack that wraps OpenClaw in policy-based privacy and security guardrails via the NVIDIA OpenShell runtime — a sandbox that routes every inference call through declarative rules and gives operators control over which data leaves the machine. Built to run autonomous agents on your own hardware (GeForce RTX through DGX) using local Nemotron models, with the option to route specific calls to cloud LLMs through a privacy router. Currently in early preview — interfaces may still change — but the most credible answer yet to running always-on agents in environments where you cannot afford a data leak.
OSS framework for building AI agents that defer to a human at key checkpoints — checkpointing, approval gates, and replayable runs are first-class. Top PH launch on 15 May 2026 (316 votes), positioned against fully-autonomous harnesses like AutoGen.
Open-source agent observability and debugging tool — token-by-token trace streaming, replay, evaluation harnesses, and self-healing suggestions that propose and test fixes for production agent failures. Integrates with Claude Code via MCP. Runs locally so traces never leave the dev machine. PH launch 14 May 2026 with 139 votes; fills a real gap in the agent-dev-tooling shelf alongside Statewright and Voker.
Open-source framework for designing agent workflows as explicit state machines instead of free-form prompt chains — every transition is auditable, every failure mode has a state to land in. Aimed at teams shipping agents to production who got burned by unbounded loops or unrecoverable errors. HN launch May 2026 with 39 pts in the emerging agent-reliability category.
YC-backed analytics platform for AI agents — track which prompts succeed, which tool calls fail, where users abandon, and how cost scales with usage. Plugs into common agent frameworks; sits in the same niche as web analytics did for the early SaaS era. HN launch May 2026 (32 pts) in the new agent-observability category.
Maintains a continuously updating changelog of what is happening across HubSpot, Slack, Zendesk, and the rest of the business stack, then serves it to your agents through a single MCP endpoint. Cuts roughly 90% of the tokens you would burn by giving agents raw API access while producing higher-quality outputs — the agent reads the curated context instead of crawling tools live. Aimed at the moment when "agent memory" stops being a research project and starts being infrastructure.
Open-source CLI that fingerprints your machine (GPU/VRAM/RAM) and recommends which open-weight models will actually run well on it, ranked by published benchmarks. Surfaced on HN 15 May 2026 with 275 points as a practical antidote to "will this 70B model fit on my Mac?" guesswork.
