Hacktron vs Relay.app Agents: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Hacktron and Relay.app Agents — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Hacktron
Hacktron AI
An AI security engineer that reviews every pull request, traces exploitable vulnerabilities and proves them with a working exploit before code ships.
Key features
- Exploit-Proven PR Review: Reviews every pull and merge request on GitHub, GitLab or Bitbucket and only reports a finding when it can attach a working exploit demonstrating real impact.
- Attacker-Path Taint Tracing: Indexes the codebase and traces tainted input through call paths to determine what an attacker can actually reach, rather than pattern-matching on syntax.
- Fix with AI in the Thread: Delivers a remediation prompt and suggested diff inside the pull request comment so the fix happens where the review already is.
- Security Automations: Set trigger conditions once and Hacktron verifies, fixes and tests every matching finding, then notifies the team in Slack or email.
- Whitebox Pentests: Launches a full-scope assessment that deploys a sandbox, builds a call graph, maps the attack surface and validates exploits, delivering an audit-ready SOC 2 or ISO 27001 report in hours instead of weeks.
- Versioned Project Rules: A .hacktron/rules.md file lives and versions with your code, encoding which paths are high risk and which findings to suppress, cutting false positives without going blind to real bugs.
- Threat Models from Your Documents: Upload architecture notes, security policies or past pentest reports and Hacktron builds and updates a versioned threat model for the application.
- Triage as Training: Every finding you accept, dismiss or downgrade teaches the system that codebase's threat model, so reviews sharpen the longer it stays embedded.
- MCP and REST API Access: Pull findings into Cursor, Claude Code or Codex over MCP to analyse and fix, or build custom workflows on the REST API, plus Jira and Linear ticket creation.
Best for
- Pre-Merge Vulnerability Gating: Catching an IDOR or injection introduced by a pull request before it reaches production, with the exploit attached so nobody debates severity.
- Replacing Annual Pentests: Running continuous whitebox assessments instead of relying on a once-a-year engagement that misses everything shipped in between.
- SOC 2 and ISO 27001 Evidence: Producing an audit-ready penetration test report in hours to satisfy a compliance deadline or a customer security review.
- Cutting Scanner Alert Fatigue: Replacing a noisy SAST queue with findings that come with proof, so the security team spends its time on real issues.
- Scaling a Small Security Team: Giving one or two security engineers coverage across every repository and every developer's pull requests.
- Dependency Supply-Chain Checks: Scanning a lock file for malicious packages before they land in the build.
- Fixing Findings from Your Editor: Pulling confirmed vulnerabilities into Claude Code or Cursor over MCP and remediating them without leaving the IDE.
Relay.app Agents
Relay (relay.app)
No-code platform to build and run autonomous AI agents that automate tasks across Gmail, Notion, HubSpot and hundreds of other apps.
Key features
- No-Code Workflow Builder: Drag-and-drop interface and pre-built templates let non-technical users design multi-step agent workflows without writing code, speeding deployment of automation.
- Multi-App Integrations: Native connectors and integration support for hundreds of apps (explicitly including Gmail, Notion, HubSpot) to read, write, and synchronize data across systems.
- Proactive Background Agents: Agents can run continuously or on schedules to monitor inboxes, databases, or other sources and take actions autonomously day and night.
- LLM Backend Support: Integrations with large language models such as GPT-4 and Claude (reported in third-party sources) to enable natural language understanding, generation, and complex decision logic within agents.
- Human-in-the-Loop Controls: Options to pause workflows for human review, approve outputs, or intervene in agent decisions to maintain quality and compliance.
- Templates for Common Tasks: Ready-made templates for use cases like lead enrichment and customer support that reduce setup time and provide best-practice starting points.
- Drag-and-drop no-code workflow and agent builder
- Pre-built templates for common automations (e.g., lead enrichment, support)
- Integrations with Gmail, Notion, HubSpot and hundreds of other apps
- LLM integrations (reported GPT-4 and Claude support)
- Human-in-the-loop controls for oversight and handoffs
- Proactive agents that operate 24/7 and improve over time
- Tiered pricing with free tier and paid plans
Best for
- Lead Enrichment: Automatically gather and append contact data from email threads, public sources, and CRMs into HubSpot or other CRM records to speed sales outreach.
- Customer Support Triage: Monitor incoming support emails or tickets (Gmail/Helpdesk), categorize and prioritize them, and either auto-respond or escalate to human agents with context.
- Automated Knowledge Ops: Create and maintain Notion pages by extracting insights from meeting notes, emails, and documents, keeping internal knowledge bases up to date.
- Email Automation and Summarization: Continuously monitor Gmail, summarize long threads, and generate suggested replies or follow-up actions for faster inbox management.
- Cross-System Orchestration: Detect events in one app (e.g., form submission) and trigger multi-step workflows across several apps (CRM updates, Slack alerts, task creation) without custom engineering.
- Monitoring & Alerting: Run agents that watch for KPI changes, exceptions, or deadlines and notify stakeholders or kick off remediation workflows automatically.
- Lead enrichment and sales engagement automation
- Customer support ticket triage and response automation
- Automating routine operational tasks across SaaS apps
- Content generation and data extraction workflows
- Integrating LLM-driven agents into existing CRM and productivity stacks
