Coldrig vs Salesforge / Forge Stack for AI agents
Choose the Forge Stack today when LinkedIn, lead sourcing, and an established multi-year production history are requirements. Choose Coldrig when you want your existing coding agent to operate a smaller, single-token, managed infrastructure-to-reply surface — real sending and push webhooks are both already live. Coldrig is not yet the winner on production track record, and new-account activation still runs through a short concierge step rather than fully automatic self-serve.
Fast decision table
| Requirement | Salesforge / Forge Stack | Coldrig |
|---|---|---|
| Real cold-email sending now | Yes; production product and trial | Yes; live in production (Gmail API, HTTPS/443) — new accounts activate via a short concierge step |
| MCP for coding agents | Hosted endpoint for Claude Code, Cursor, and other MCP clients | Hosted streamable-HTTP endpoint plus REST and npm CLI |
| Authentication shape | One endpoint; separate product headers/keys for each Forge product used | One tenant bearer token for all 24 intents |
| Infrastructure | Mailforge, Infraforge, or Primeforge; Warmforge for warmup | One intended managed lifecycle behind setup_infrastructure |
| Lead sourcing | Available through Leadsforge | Not included |
| Email + LinkedIn | Supported | Email only |
| Webhooks | Salesforge's official MCP help lists webhooks in the supported surface | Yes — get_webhooks/configure_webhook push reply, bounce, soft_bounce, and complaint events (HMAC-signed); activity remains pollable too |
| Agent surface philosophy | Broad, product-specific controls across the Forge products configured | 24 outcome-level intents across Coldrig's documented lifecycle |
| Production track record | Established product with public customers and reviews | Real sending live in production as of today; no established multi-year track record yet |
Where the Forge Stack is stronger
- Its agent story is explicit. Salesforge publishes setup instructions and operating workflows for Claude Code and Cursor, not merely a generic API.
- It covers more jobs. Lead search and enrichment, email and LinkedIn, AI-assisted sequence work, placement tests, and several infrastructure choices are available across the Forge products.
- It has an established track record Coldrig lacks. Years of production history, a customer base, public reviews, and a live trial all reduce buyer risk in a way one day of proven sending cannot yet match.
Where Coldrig's design is different
- One tenant credential. The agent does not need one API key per configured product.
- One managed state model. The intended customer experience hides the boundaries between registrar, mailbox, warmup, campaign, reply, and safety state.
- A smaller intent surface. The agent asks for outcomes such as
setup_infrastructureandlaunch_campaigninstead of operating several product object models. - No competing strategy agent. The user's chosen agent owns research and copy; Coldrig stays an execution layer.
Those are architectural advantages only when they match the owner's constraints. They do not substitute for years of production track record, which Coldrig does not yet have.
Pricing: compare the all-in stack
Salesforge currently lists Pro at $48/month on monthly billing ($40/month annual) and Growth at $96/month ($80/month annual), with a 14-day trial. Mailforge, Infraforge, Primeforge, Leadsforge, and some other capacity are priced separately or by usage; calculate the exact set of products and mailbox type required. Coldrig's formula is $49/month for the platform plus $10 per provisioned mailbox, with a five-mailbox minimum. That is $99 for 5 mailboxes, $149 for 10, $199 for 15, and $249 for 20. Real sending and live billing (Stripe, self-serve checkout) are both live at this pricing; new accounts still activate real sending through a short concierge step.
Bottom line
If the requirement is “run a real, agent-managed cold-email operation with years of production evidence behind it,” the Forge Stack is the lower-risk recommendation today. If the requirement is “test whether one stateful, agent-controlled abstraction with real sending and push webhooks already live can replace a multi-product integration,” Coldrig is worth a pilot — start with the free sandbox, then request activation. Re-evaluate the track-record gap as Coldrig accumulates real production history.
