Price
Octolens Pro is $199 a month monthly or $159 a month annual. It includes 15,000 mentions, 10 keywords, API, webhooks, and MCP. Scale is $599 monthly or $499 annual and adds 50,000 mentions, 40 keywords, and four source types that Pro excludes. A free agent tier offers 50 searches with no credit card.
Brand24 Individual is $199 a month annual or $249 monthly with 3 keywords, 2,000 mentions, and refresh every 12 hours. Team is $299 annual. Pro is $399. Business is $599. Enterprise starts at $1,499. API access is a paid add-on on the Business tier. The cheapest path to a Brand24 API is about $698 a month.
Octolens is cheaper per mention and includes API on every plan. Brand24 gives more keywords at the entry tier (3 versus 10) but Brand24 Individual has only 2,000 mentions and refreshes every 12 hours. The API gap is the largest difference: $159 a month at Octolens versus about $698 at Brand24.

Sources
Octolens has 15 source pages covering Reddit, Hacker News, Bluesky, GitHub, Stack Overflow, DEV, X, LinkedIn, TikTok, YouTube, Mastodon, podcasts, newsletters, news, and web. Podcasts, news, web, and newsletters are Scale-only.
Brand24 claims over 25 million sources. Its 12 platform pages cover Reddit, X, TikTok, Instagram, YouTube, and review sites. Sources are gated by plan. No pages exist for LinkedIn, Bluesky, Hacker News, Discourse, Mastodon, GitHub, or Stack Overflow, despite the llms.txt naming several.
Octolens has more developer sources: Hacker News, GitHub, Stack Overflow, DEV, and Mastodon. Brand24 has more mainstream sources: Instagram, Facebook, and TikTok are tracked on all plans. Both cover Reddit, X, YouTube, and LinkedIn, but Brand24 gates LinkedIn to the Team tier.
Agent surface
Octolens ships llms.txt, llms-full.txt (629 KB), a 52-path OpenAPI spec, .well-known/mcp.json with 23 tools, agent-permissions.json, an npm CLI, and 11 agent skills. Its MCP uses OAuth and is available on every plan. It is listed on the MCP registry.
Brand24 ships an llms.txt (33 KB), a pricing.md for agents, and an MCP server at mcp.brand24.com with OAuth. The MCP is documented only in a help-center article, not on the main domain. No .well-known/mcp.json, no agent-permissions.json, no CLI.
Octolens has a more complete agent discovery kit. An agent searching for tools would find Octolens through the MCP registry, OpenAPI spec, or mcp.json. It would find Brand24 only through llms.txt or a direct URL. Neither pushes to an agent when a mention lands.
Brand24’s API is aggregate-first. The OpenAPI spec is "Brand24 API Data" with endpoints for project-level stats, sentiment, reach, and AI summaries. Individual mention retrieval exists but requires a dashboard-created project and a 31-day query window. Octolens’s API is mention-first with 52 paths covering mention listing, analytics, keyword CRUD, and usage. Both use API-key auth.
Freshness and trust
Octolens published 26 blog posts in 2026 at roughly 3.5 a month. Nearly all content is by the CEO. It has 28 customer logos and no /about page. G2 lists it at 4.69 from 36 reviews. It has been operating since 2023.
Brand24 published about 97 English blog posts in 2026 at roughly 8 a month, slowing from 20 in spring to 5 in summer. It has 25 authors with expertise tags, 63 case studies, and logos from Capterra and GetApp. G2 lists it at 4.6 out of 5. It has been operating since 2011.
Brand24 has stronger E-E-A-T signals by every measure: more authors, more case studies, more content, and thirteen years of operation. Octolens has bigger developer logos (Vercel, PostHog, Sentry) and a higher G2 rating.
Who should pick which
Pick Octolens if you are building an agent workflow, need API and MCP on a self-serve plan, and value developer sources like Hacker News, GitHub, and Stack Overflow. The free 50-search tier lets an agent evaluate it without a credit card.
Pick Brand24 if you want a marketing dashboard with broad source coverage, weekly blog updates, 25 authors, and 63 case studies. Expect to pay at least $199 a month and about $698 a month if you need API access.
The third option
discatch is a social listening API and alert system built for agents. It sells by the unit, not the seat. API and MCP are planned on every plan including the free tier. Catches push to an agent when they fire.
