Best Developer Tools products of the month September 2026

TrustedRouter

Every model with a unified interface. Privacy with proof.

TrustedRouter gives you a single OpenAI-compatible API to access hundreds of AI models, all running on attested infrastructure with end-to-end encryption. You get Confidential routes for sensitive workloads, ZDR (Zero Data Retention) routes, automatic provider failover, and the ability to bring your own keys (BYOK). Best of all, we don't log any prompts or outputs, so your data stays private.

Elva

Goodbye, Postman. Your APIs have new consumers

Developers use your APIs. Now agents do too. Elva discovers APIs directly from your code, lets you choose what each audience can use, and runs your MCP servers with authentication and analytics built in. You can track agent activity, see how your APIs are being used, and review changes as your code evolves. It gives you the visibility and control you need to open your product to AI agents without losing security or oversight.

Olostep

Web search, scraping and crawling for AI

Olostep's Web Data API lets you extract, crawl, and structure web data at any scale. Designed for AI teams, data pipelines, and automation, it delivers fast, reliable, and cost-effective data collection. With robust handling of dynamic pages and anti-bot measures, you can focus on building while Olostep handles the scraping complexity.

Superagent

Claude Code for the rest of us

Superagent gives your coding agent a proper home, so working with it feels like using a polished Mac app instead of a terminal. It hands your agent a full computer: a real browser it can drive using your logged-in sessions, an iOS Simulator it can tap and swipe, access to your files, a board it maintains, and routines on a timer. Chats live in a sidebar you can organize into groups, they survive restarts, and they don't steal your focus. Each agent runs on its own git worktree, so you can switch contexts easily. Pair your iPhone and the work follows you, with end-to-end encryption. No account, no server, no extra bill. It's open source.

Arcjet

Secure the AI agents you're building at runtime

Arcjet is a runtime security platform that lives right inside your AI code, giving you real-time protection exactly where you need it. It helps you detect and block prompt injection attacks, authorize which tools your AI agents can call, automatically redact sensitive data, and stop bots and abusive traffic before they cause harm. The best part? Everything is implemented as simple building blocks you call directly in your application logic, so security checks happen at the exact moment an action is about to occur. No external service round-trips, no latency spikes, just clean, immediate enforcement. If you're building with AI, Arcjet is the safety net that keeps your system secure and your data private.

FreeScan.app

Fix what’s hurting your visibility, trust, and conversions

FreeScan lets you audit any public URL for free, no signup required. It digs deep to uncover problems and missed opportunities across SEO, AEO, GEO, security, accessibility, and design. Every finding comes with evidence, an explanation of why it matters, and a clear path to fix it. For more advanced needs, the Pro version runs automated site-wide audits and organizes everything into dedicated workspaces for SEO, AI Visibility, and Fixes. It tracks improvements and regressions over time, creates agent-ready artifacts, and connects with coding agents through MCP. You also get uptime monitoring, weekly reports, and downtime alerts. Whether you're a solo developer or part of a larger team, FreeScan helps you keep your site healthy and ahead of the competition.

Switch

Bring any AI agent into Slack, Teams & Discord

Switch brings AI agents into the collaboration tools your team already uses. Agents join as named participants in your Slack, Teams, Discord, or Telegram channels, sharing the same context and history as your team. Connect an agent once and use it across projects. Each room carries its own context, participants, and rules. Works with Claude Code, OpenAI, Google ADK, LangChain, and more. Open source, self-hostable, running in minutes.

Airuncode

Run multiple local coding agents on your machine

Airuncode is a local-first agent runtime for serious software work. Run multiple coding agents on your machine, bring your own API keys, switch between cloud and local models, and pay providers directly with zero token markup. It scans your codebase, debates solutions across agents, edits files, runs tests, and self-heals failures. It also ships with V-CORE, a native Vulkan 3D runtime for AI-assisted game development. Available on Windows, macOS, and Linux.

GoModel

Open-source OpenRouter

GoModel is an open-source AI gateway written in Go. It gives you one OpenAI-compatible API that works with any provider, while also handling budgets, caching, guardrails, load balancing, and failover. You can run it as a single binary or as a Docker image around 20MB in size. The MIT license and bring-your-own-keys approach make it flexible, and it is a strong self-hosted alternative to OpenRouter and LiteLLM.

Modeinspect

99 Days Free AI Credits - Design product UI in your codebase

Most software gets designed twice: first as a picture, then again in code. That's where the intent gets lost. Modeinspect is an AI-powered design canvas that lets you work with the real thing from the start. Connect your codebase, open an existing screen, and design using your actual components, tokens, live data, states, and breakpoints. You can explore variations with AI, keep the details that matter, and when you're ready, publish your changes live or send them to engineering for review. You stay in control of when things go live. The canvas isn't the destination; the product is. Modeinspect bridges the gap between design and development, so what you see is truly what you get.
