6 Best Developer Tools for AI Agent Builders

Updated Nov 1, 2026

Powabase is a hosted backend for AI apps, with a free plan and paid plans from $25/mo. You get a separate Postgres database for each project, plus auth, file storage, a retrieval pipeline for your documents and a runtime for agents, all behind one REST API.

The win is fewer moving parts: no separate vector store or agent framework to keep in sync. It builds on the Supabase stack, so the database side will feel familiar.

It ranks first because it covers the widest part of the job (data, retrieval and agents), has the most Product Hunt upvotes here, and you can start free.

Best for: small teams building a support agent or document assistant who don't want to run a vector database next to their app.

Skip it if: you only need a database and auth. Plain Supabase covers that, and Powabase says as much.

Pricing: Free plan with $10 in credits at sign-up and pay-as-you-go compute; Self Serve $25/mo with $25 in monthly credits; Scale $300/mo (checked Nov 1, 2026).

What stood out: 468 upvotes on Product Hunt after its May 31, 2026 launch, the most on this list. No saves or reviews on Launch Llama yet.

Limitation: Free-plan projects are suspended after 7 days of inactivity and deleted after 30.

ClawSecure is a security scanner for AI agent skills and MCP servers, with a free scanner and founding-member plans from $9.99/mo. Paste a GitHub link and it returns an audit report with a score and fixes, no account needed.

Best for: developers who pull community skills into Claude Code or Cursor and have nobody on security.

Skip it if: you need runtime monitoring today. Only the scanner is live.

Pricing: Free scanner; Shield $9.99/mo at the founding-member rate ($29/mo standard), Sentinel $24.99/mo, Fortress $79.99/mo (checked Nov 1, 2026).

Limitation: The paid tiers are waitlist-only right now, and the monitoring daemon sends component metadata and file hashes to ClawSecure's cloud.

What stood out: 303 Product Hunt upvotes, second on this list.

Agentmemory is an open-source memory server for coding agents, free under the Apache-2.0 license with no paid tier. It records what happens in each Claude Code, Codex or Cursor session on your machine and lets the agent search it later, so you stop pasting the same project notes into every chat.

By default nothing leaves your laptop, and an LLM key is optional.

Best for: solo developers who use a coding agent every day on the same codebase.

Skip it if: you want a hosted, managed service. There isn't one.

Pricing: Free and open source; the site states there is no hosted tier (checked Nov 1, 2026).

What stood out: 253 Product Hunt upvotes at its May 17, 2026 launch.

Limitation: It needs Node.js 20 or newer, and you run and update the server yourself.

MCP Bridge by Appfactor is a gateway that converts existing REST, GraphQL, SOAP and gRPC APIs into MCP tools, offered as a free trial with prices not stated publicly. Point it at an API schema and your agents get typed tools, with auth and usage analytics in one place.

Best for: platform teams that have dozens of internal services and don't want to write an MCP server for each one.

Skip it if: you have one or two APIs. Writing a small MCP server yourself is probably faster.

Pricing: Free trial, no credit card; paid tiers via AWS and Azure Marketplace, price not stated by the vendor (per Launch Llama listing).

Limitation: No public price list, and the marketplace route points at enterprise buyers.

Raindrop is a debugger for AI agents, with a free plan and paid pricing not stated publicly. Its open-source Workshop runs locally and shows each run token by token, including tool calls, so you can see where an agent went wrong instead of guessing from the final answer.

Best for: engineers whose agent "works" in demos but fails quietly in production.

Skip it if: you need to know the production price before you start. It isn't published.

Pricing: Free plan, no credit card (per Launch Llama listing; the pricing page returned an error on Nov 1, 2026).

What stood out: 175 Product Hunt upvotes in May 2026.

Limitation: Paid plans and their limits are not stated by the vendor.

Integuru is an API generator for websites that have no public API, with a free plan and paid plans from $499/mo. It studies a site's network calls and builds an API your agent calls directly, login and two-factor steps included, instead of clicking through a headless browser.

This is the specialist pick: if your agent must work inside an EHR or payer portal, nothing else here does that.

Best for: teams in healthcare, logistics or finance whose agents depend on legacy web portals.

Skip it if: the systems you need already have official APIs, or $499/mo is out of reach once you pass the free tier.

Pricing: Free plan with 100 API calls/month on 1 platform; Production from $499/mo for 10,000 calls; extra platforms $499/mo each (checked Nov 1, 2026).

Limitation: The free plan covers one platform and one account, which is enough to test, not to run.

Starting an agent app from scratch? Pick Powabase. If budget is the constraint and your coding agent keeps forgetting your project, Agentmemory costs nothing. Installing skills written by strangers? Run them through ClawSecure first. For company APIs, use MCP Bridge; for websites with no API, Integuru. If you only use ChatGPT or Claude in a browser and don't write code, skip this list entirely. You can also browse more developer tools on Launch Llama.

Supabase is the simpler choice if you only need Postgres and auth without the AI layer. For coding-agent memory, PMB stores everything in one SQLite workspace, which suits people who prefer a file over a server.

All six launched on Product Hunt in May 2026, with 170 to 468 upvotes. None has saves or reviews on Launch Llama yet, so upvotes are the only traction signal, and they are modest.

Yes. Agentmemory is free and open source under Apache-2.0, runs locally, and works with Claude Code, Codex, Cursor and other MCP clients.

Paste its GitHub link into ClawSecure's free scanner. It needs no account and returns an audit report with a security score and suggested fixes.

Yes. Integuru builds an API from the site's own network requests, so the agent doesn't need a browser. The free plan covers 100 calls a month (checked Nov 1, 2026).

I looked for tools that solve one clear problem for agent builders, with a real product screenshot and a substantive listing. I reviewed 94 candidate rows: 84 Product Hunt launches tagged Developer Tools from the last 180 days and 10 premium listings. Most recent launches were dropped for thin listings or no screenshot; the premium listings had no audience data; Apideck was dropped as a weak fit (it centers on accounting integrations), and Launch Llama's own MCP Shelf was excluded. All six picks are Product Hunt launches with upvotes. These picks are based on listing data, launch traction and pricing pages; none of them were tested hands-on.
