If you've been running an OpenClaw agent for a while, you've probably hit the same wall: the agent itself is powerful, but connecting it to the real world requires the right tools. After testing dozens of integrations — many of which were disappointing — here are the five free tools that have genuinely changed how our agents operate at RemoteOpenClaw.
1. AgentMail — Email Built for AI Agents
Most people try to hook their OpenClaw agent up to a standard Gmail account, and most of them run into problems. Gmail increasingly flags automated activity, and the friction adds up fast.
AgentMail (agentmail.to) solves this by providing email infrastructure designed specifically for AI agents. No bot detection headaches. No deliverability workarounds.
Getting started is straightforward:
- Create an account at agentmail.to
- Navigate to API Keys and copy your key
- Hand the key to your OpenClaw agent — it figures out the rest
The free tier is enough to get started. If you want your agent's outgoing emails landing in primary inboxes rather than promotions folders, you can warm up the address or connect a custom domain — but for most agent use cases, the default setup works well out of the box.
Best use case: Any workflow where your agent needs to send, receive, or monitor emails on your behalf.
2. Here.now — Instant Shareable Hosting
Ever had your agent produce a document, dashboard, or mini-site and wanted to share it with someone immediately? Here.now is the answer.
You don't even need to configure anything. Tell your agent to "publish to here.now" and it gets back a live URL within seconds. Lightweight websites, marketing plans, shared reports — anything without a back-end database is fair game.
Key details:
- No account required — links stay live for 24 hours
- Free account (email only) — links are permanently hosted
- Works with any agent framework, not just OpenClaw
How to set it up: Either tell your agent to look up here.now and install it, or visit here.now in your browser, click Copy Setup Instructions, and paste them directly to your agent. That's it — you're done.
Best use case: Sharing deliverables instantly without spinning up any hosting infrastructure.
3. Tavily — Web Search That's Actually Free
If you've been using Brave Search for your agent's web browsing capability, you may have noticed the pricing has changed — it's now a paid tier for meaningful usage. Tavily (tavily.com) fills that gap.
It's built for agents, which means it searches faster than a standard browser integration and returns cleaner, more structured results. The free tier includes roughly 1,000 searches per month — more than enough for most individual setups.
Setup: create a free account at tavily.com, copy your API key, and give it to your agent.
Best use case: Any research task, competitor monitoring, or news gathering workflow.
4. Firecrawl — Turn Any Website Into Clean, Usable Data
Tavily finds the page. Firecrawl reads it deeply.
Firecrawl (firecrawl.dev) takes a URL and returns clean, AI-ready content — stripping out ads, navigation clutter, and irrelevant markup. It's the difference between dumping raw HTML at your agent and giving it structured, useful information.
Practical applications:
- Scraping competitor product pages and pricing
- Extracting structured information from content-heavy sites
- Monitoring specific pages for changes over time
The free credit tier is generous. You can track your usage directly in the Firecrawl dashboard.
Setup: Create an account, grab your API key, pass it to your agent, and instruct it: "Use Firecrawl whenever I ask you to scrape or deeply read a website."
Best use case: Competitor research, content extraction, and any workflow where you need clean structured data from the web.
5. Remotion — Programmatic Video Generation
This one tends to get the strongest reaction from people who haven't seen it before.
Remotion lets your OpenClaw agent create videos programmatically — no editing software, no timeline scrubbing, no manual export steps. You describe what you want, and the agent builds it. Want to tweak the colors, resize an element, or change the text? You describe the change, and it updates.
Free tier: The core functionality is free and, for most use cases, you won't need to upgrade.
How to use it: Tell your agent to install Remotion. Once it's installed, you can request videos conversationally — short promo clips, milestone announcements, social content snippets, and more.
Best use case: Content creators, marketers, or anyone who needs short-form video without a video production workflow.
Setting Up All Five
You don't need to configure all five tools at once. A practical starting point:
- Install AgentMail if your agent handles any email tasks
- Install Tavily so your agent can search the web for free
- Add Firecrawl once you have a specific scraping use case in mind
- Install Here.now for any time you want to share agent output as a link
- Add Remotion when you're ready to experiment with video
Each tool requires only an API key passed to your agent — and once connected, your agent handles the rest without any manual workflow configuration on your end.
What to Try Next
With these five tools in place, your OpenClaw agent can send email, host and share content, search the web, scrape websites, and produce video — all for free, and all without you needing to wire up complex automations manually.
