### 2. Affiliate program software for brands (run‑your‑own program)

These tools let you host and manage your own affiliate/referral program rather than only joining an external network.

- **ReferralCandy**

- 2026 “8 Best Affiliate Program Software” list ranks it #1 for **Shopify brands wanting referral and affiliate in one platform**.[2]

- Popular among DTC e‑commerce brands because it natively combines referrals and affiliates and integrates with Shopify.[2]

- **Post Affiliate Pro**

- Markets itself explicitly as “Best Affiliate Marketing Software 2026” for running in‑house programs, emphasizing robust tracking and cost‑control.[6]

- Long‑standing tool used by many SMEs to manage custom affiliate structures.[6]

- Other tools frequently mentioned in 2026 roundups (per GrowSurf, Jotform, etc.) include white‑label or plug‑and‑play affiliate solutions, but the consistently named leaders are ReferralCandy and Post Affiliate Pro for mid‑market brands.[2][4][6]

### 3. Dedicated affiliate tracking & optimization tools (for pro affiliates/media buyers)

These are especially popular with performance affiliates running ads, funnels, and multi‑traffic‑source campaigns.

- **Voluum**

- A 2026 affiliate tools guide calls Voluum the **“undisputed champion”** among dedicated affiliate tracking platforms, designed specifically for affiliates from day one.[5]

- Widely used for advanced tracking, attribution, and optimization.[5]

- **RedTrack**

- Listed alongside Voluum as a top 2026 tool for affiliates, positioned as a competing cloud tracker starting at a lower price point.[5]

- Popular among media buyers seeking multi‑channel attribution.[5]

These tools are less about running a merchant’s affiliate program and more about helping affiliates optimize their own campaigns, but they are highly popular within the affiliate community.
