Salty vs Day.ai
The programmable agent CRM vs the auto-building AI CRM.
Salty and Day.ai are both agent-era CRMs that reject per-seat pricing, but they take opposite approaches. Day.ai is an AI-native CRM that auto-builds and maintains itself from your email, calendar, meetings, and Slack, then runs AI "Assistants" — priced per Assistant from about $30/mo, with an official MCP server and TypeScript SDK but no documented public REST API and no webhooks. Salty is a programmable system of record: a full REST API (OpenAPI 3.1), a native MCP server, a CLI, and HMAC-signed webhooks, priced per API call. Choose Day.ai if you want AI to keep a GTM CRM up to date for human sellers; choose Salty if you’re building agents that need a programmable database with webhooks and open REST access.

What is Salty?
Salty is a developer-first CRM built for AI agents instead of human reps. It exposes one workspace through four programmatic surfaces — a REST API (OpenAPI 3.1), a Model Context Protocol (MCP) server with 15 tools, a CLI, and HMAC-signed webhooks — and prices on API calls rather than per seat. There are no kanban boards, dashboards, or integration marketplace; the agent does the work and Salty is the database underneath.
What is Day.ai?
Day.ai is an AI-native CRM that automatically generates and maintains CRM records from your email, calendar, video meetings, and Slack — no manual data entry — then layers on Day AI Assistants (agents that research, draft, and build reports) and AI Pages. Founded by ex-HubSpot CPO Christopher O’Donnell, its 2026 positioning is Claude- and agent-centric.
Pricing: Salty vs Day.ai
Day.ai pricing as of June 2026. Verify current figures on the vendor’s pricing page (linked in sources below).

- Pro$99/mo1,000,000 API calls/mo · 250,000 records · every feature
Pricing is per API call, not per seat — every MCP tool call and REST request counts as one call; admin/billing actions are exempt. Overage is $1 per 10,000 calls (and $0.50 per 1,000 records over cap). There is no per-user fee, so a fleet of agents costs the same as one.
- Free$0Meeting recording + AI notes
- Paidfrom ~$30/moBilled per AI Assistant, not per seat
Day.ai bills per AI Assistant (agent), not per seat — there is no per-seat charge. A free account includes meeting recording and AI notes; paid tiers (Turbo / Professional / Executive) start around $30/mo. See Day.ai’s pricing page for current higher-tier figures.
When to choose Salty
- You’re building agents that need a programmable database with a full public REST API.
- You need webhooks — Day.ai has none, so it can’t push changes to your services.
- You want predictable per-call pricing rather than per-Assistant/usage costs that are harder to forecast at high volume.
- You want a clean system of record your agents fully control via REST, MCP, and CLI.
When to choose Day.ai
- You want AI to build and maintain the CRM automatically from email, calendar, and meetings.
- You’re a GTM/sales team that values zero manual data entry and meeting prep.
- You want built-in AI Assistants and AI Pages without writing agent code.
- Customer "memory" queryable inside Claude matters more to you than open REST + webhooks.
The bottom line
Day.ai is excellent when you want AI to keep a sales CRM current for human sellers with no data entry. Salty is the better fit when you’re the one building the agents and need a programmable system of record: a full REST API, native MCP, and HMAC-signed webhooks — the last of which Day.ai lacks. Both drop per-seat pricing; Salty meters per call, Day.ai per Assistant.
Salty vs Day.ai: FAQ
- Does Day.ai have a public REST API?
- Not a documented standalone REST or GraphQL API. Day.ai’s programmatic surface is an official TypeScript SDK plus an MCP server; integration is SDK/MCP-shaped rather than open HTTP. Salty ships a full public REST API (OpenAPI 3.1) alongside its MCP server and CLI.
- Does Day.ai support webhooks?
- No webhook or event system was found as of June 2026, so Day.ai can’t push record changes to your own services. Salty includes HMAC-signed webhooks with 8-attempt exponential backoff on every paid tier — events for created, updated, and deleted records across every object type.
- How does Day.ai pricing compare to Salty?
- Both avoid per-seat fees. Day.ai bills per AI Assistant (from about $30/mo) with a free account for meeting notes. Salty bills per API call: $20/mo for 100,000 calls, $99/mo for 1,000,000. For high-volume agent traffic, Salty’s per-call model is easier to forecast.
- Should I use Day.ai or Salty?
- Use Day.ai if you want an AI to auto-build and maintain a CRM for human sellers from your communications. Use Salty if you’re building agents and want a programmable system of record with open REST access and webhooks. They can also coexist — Day.ai for the human side, Salty as the agent-driven datastore.
