Write a workshop as one plain Markdown file and run it live. Students join with a code - no accounts - and you see which step everyone is on: who's stuck, who's done, who needs help. Polls, quizzes, chat and a session report built in. Free, no credit card.
A mission-control dashboard for teams shipping on Vercel. Connect your account and every project fills in live: traffic, deploys, uptime, and PageSpeed scores. Search Console and Bing show clicks, rankings, and indexing. SSL and domain renewals get a countdown, and failing GitHub checks get flagged. When a build fails, the menu-bar F turns red and a notification fires, even with the window closed, so you know a site's down before your clients do. Tokens stay on your Mac. One-time purchase.
Hello Inbox helps marketing teams get more emails into the inbox instead of spam. Test your campaigns before you send, see what is hurting deliverability, and get clear recommendations for what to fix. Instead of throwing deliverability scores and technical data at you, Hello Inbox turns the results into actionable steps so you can improve inbox placement without becoming an email deliverability expert.
Your bookmarks have more to give. Marqly 6.0 adds an AI Assistant that answers from your saves, an AI Organizer that proposes a cleaner library for you to review, and MCP to bring your saved research into Claude, ChatGPT, and Cursor. Keep articles, highlights, videos, and AI chats together. Available on the web, in your browser, and on iOS. Android is coming very soon. AI features are included in Pro.
Same push-to-deploy you already know, running on a machine you already pay for. No Docker. No SSH. No invoice.
DemoTV is a 24/7 channel of product demos, ranked by the people watching. Submit a short demo for free. Viewers watch head-to-head Channel Battles and back the product they'd actually try, and an Elo-style audience score decides who sits on Channels 1-3. Businesses can buy clearly labelled airtime: money buys exposure, completed views and clicks, never the ranking.
The gap between 1.5x and 100x isn't speed, it's trust!! AI agents generate code 100x faster than humans write it. But your team can't review it all. EasySpecs documents undocumented codebases and turns them into trustworthy specifications, so spec review becomes your new merge request review. Ground your agents in reality. Scale agentic development without babysitting. Document the foundation once. Review specs including Oracles and Rubrics and Ship code you actually verified.
Free help desk software with unlimited agents and unlimited tickets. Email-to-ticket, SLAs, automations, knowledge base. No credit card required.
Nova is the AI Operator that builds and improves your AI customer experience team, no developer required. Describe in plain language how customers should be handled and connect your tools. Nova builds the agents, tests them on past tickets and shows you what failed before anything goes live. Once running, it monitors quality and proposes fixes 24/7 for approval. Agents resolve whole requests, from orders and refunds to plan changes, across email, chat and WhatsApp. Unresolved requests are free.
AdScope transforms confusing ad data into clear visual dashboards for agencies and business owners. We display your actual ad creatives right next to the metrics that matter most. During onboarding, you define your business type like e commerce or lead generation, and your main overview adapts instantly. Campaign metrics also adjust dynamically based on campaign type. This creates total transparency and builds instant trust. Stop guessing and understand your ad performance in five seconds.
Noodle Seed helps software teams make their products ready for AI agents. Build workflows in TypeScript, expose them through a secure branded assistant inside your product, and make the same capabilities available to external agents. Instead of stitching together MCP SDKs and hosting infrastructure, Noodle Seed provides the governed runtime for identity, permissions, secrets, audit, and operations.
Widgo is an AI sales rep on your website. It scans your site, adds any docs you give it, and answers every visitor from that alone. It identifies the company, scores the lead, and books the demo on your calendar. One line of code. Free forever, no card.
Finding new customers takes way too long and most of that time goes into work nobody wants to do. So we built Tables. You write who you are looking for in normal language and Tables goes through 300M+ verified contacts, looks into each one and answers the questions you actually care about. You get a scored list with emails, phone numbers and the sources behind every answer, so you can check it. Syncs with HubSpot, Pipedrive and Attio, and works on LinkedIn and inside Claude.
Most people who want a specific domain name have no way to know when a real opportunity to acquire it appears. Notify.domains monitors WHOIS, RDAP, auctions, marketplaces, website signals, and more, checking each domain 20+ times per day across all IANA TLDs. When something changes, you get a plain-English notification with exact next steps, not raw data. $24/year, 7-day free trial, no credit card required.
Reflexio makes AI agents better with every interaction. When users correct an agent, a path fails, or something works particularly well, Reflexio turns that experience into behavior the agent can reuse next time. Instead of leaving valuable lessons buried in logs, your agent continuously learns what to repeat and what to avoid — with every learning visible, testable, and reversible. Reduce task failure rate by more than 30%, while saving tokens by more than 60%.
HyperProbe is how backend teams debug production issues they can't reproduce locally. Instead of adding a log line and waiting on a deploy, we let Claude Code, Codex, or Cursor drop read-only probes into a running service and capture the variable state that was never recorded. From there your agent debugs like it has a local repro, closing the bug in one sitting.
Compliance by TwelveLabs is a SaaS application that reviews your video library against rules your team writes, not ours. It ingests footage, applies your own compliance rule packs, and returns reviewer-ready findings with context, not just a timestamp and a label. Powered by TwelveLabs' Pegasus model, it explains why a moment may violate a rule so reviewers can accept, reject, or annotate in one queue.
Nex builds and runs the complex, high-volume GTM workflows that general-purpose agents struggle with. Built by ex-HubSpotters who ran its three largest customer platforms and backed by HubSpot founder Dharmesh Shah.
The changelog is the last chore of every release, so hand it to the agent that wrote the code. Onset MCP lets Claude or Cursor draft, schedule, and publish your release notes without leaving the editor. Free plan, no credit card.
Userlens helps SaaS teams turn product behavior into timely, personal guidance. Lumi, our adoption agent, combines warehouse and analytics data to understand every account, find users who are falling behind, and draft the right message for their context. You set the goal, audience, tone, and guardrails. Lumi personalizes each nudge and measures whether users actually adopt the feature.
Articos helps SaaS teams, agencies, and founders test messaging, positioning, and landing pages against simulated personas matched to your ICP. Real audience signal in under 30 minutes. Peer-reviewed at 86% human accuracy vs Baymard and Nielsen Norman.
