What is Dub?
Dub adds AI application screening as its partner program controls keep getting finer.
Dub's run since July is almost entirely Dub Partners. Programs can now auto-reject applicants against plain-language criteria, set rewards per partner or per link, pay retainer-style fixed amounts, and let existing partners apply to switch groups. Bounties and email campaigns gained tag scoping and combined conditions, while the link product got one-click DNS setup for Vercel and Cloudflare.
What is Robusta?
Robusta's recent releases patch its runner image rather than add features.
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.
Dub vs Robusta: editorial side-by-side
Dub
5.0INFRA · APIS
Dub adds AI application screening as its partner program controls keep getting finer.
◆ Current state
Dub's run since July is almost entirely Dub Partners. Programs can now auto-reject applicants against plain-language criteria, set rewards per partner or per link, pay retainer-style fixed amounts, and let existing partners apply to switch groups. Bounties and email campaigns gained tag scoping and combined conditions, while the link product got one-click DNS setup for Vercel and Cloudflare.
◆ Where it's heading
The partner product is moving from commission setup to program operations. Retainers and link-level rewards widen what can be paid for, and AI now appears in two administrative jobs, reward building and application screening. Each release reduces a manual step for program operators.
◆ Prediction
Expect more AI help in program administration, since reward building and screening shipped within two months of each other. Further reward primitives are also likely given the pace since July.
Robusta
5.0INFRA · APIS
Robusta's recent releases patch its runner image rather than add features.
◆ Current state
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.
◆ Where it's heading
Since late August the project has been treating its container image as the product surface that needs attention, with CVE patching handled by backporting packages from the next Debian release. The feature line that added workflow chaining, JSON logs and new alert sources has gone quiet in these entries. The 0.53 tag does not appear in the feed, so part of the picture may be missing.
◆ Prediction
Expect more runner-image CVE releases on the alpha line. Whether feature work on Holmes integration or alert sources resumes is not visible in these entries.
