Flagsmith gives software engineering teams a self-hosted or fully managed feature flagging platform for controlling releases across web, mobile, and backend systems. Ship code behind a flag, then decide who sees it — by environment, user, or custom segment — without redeploying.
Run Flagsmith however fits your infrastructure: our managed cloud, your own private cloud, or fully on-premise.
What you get:
Progressive rollouts with one-click rollback if something breaks
Live config changes — flip features on or off instantly, no redeploy required
Segment-based A/B and multivariate testing
Project and role-based access control for multi-team organizations
Native integrations with the tools already in your stack
MCP support and a CLI so AI agents and scripts can manage flags directly
Open source at its core, Flagsmith is built for teams that want control over where their configuration data lives.

Mentornity is mentoring and coaching program software for organizations that run structured programs and need to show what came of them.
It covers the full cycle. Participants enrol and are matched by an algorithm that scores every possible pair against weighted criteria the program defines, discarding pairs that fail a mandatory rule; administrators approve suggestions individually or in bulk, assign by hand, or open a mentor pool and let participants choose. Mentors publish availability, mentees book within it, sessions sync to Zoom, Microsoft Teams or Google Meet, and reminders go out automatically before and after each meeting.
Measurement runs alongside rather than after. Surveys and forms can be scheduled at any point in a cycle, and a program health score tracks participation, meeting frequency and completion against each program's own targets, flagging programs that drift before the cycle ends. Certificates are issued automatically on completion.
Each program runs under its own branding on its own domain, with role-based access and six interface languages. Free for up to 10 users with no expiry and every feature enabled; paid plans start at $289 per month and scale by participant count.
Running mentoring programs since 2015.

Flagship.io
Flagship.io is an online platform for feature flagging that allows modern engineers and product teams to eliminate the risk of future releases. It separates code deployments from these releases, which reduces the risk of future releases. Flagship allows you to accelerate development cycles and ship anywhere, anytime, even Friday nights.
Flagship takes the concept of feature flags to a new level, giving you complete control over the release process. Flagship allows you to:
Remote Configuration: Switch between active and inactive features.
- Code deployments can be separated from future releases. This allows engineering teams to deploy code at their own pace and product teams to release these features when it's ready.
- Automatically roll out your features gradually to monitor performance and gather feedback from your most important users.
- Revert any feature that causes problems while being tested in production, while your team investigates the issue.
Segment users by granting them access to a feature

Hypertune
Hypertune stands out as a highly adaptable platform that excels in managing feature flags, conducting A/B testing, performing analytics, and configuring applications. It is designed with comprehensive end-to-end type safety, Git-inspired version control, and allows for local, synchronous, in-memory flag evaluations.
You can establish type-safe, tailored inputs such as the current User or Organization to fine-tune feature flag rules, ensuring precise targeting of your desired audience. Furthermore, the platform enables the creation of reusable variables like user segments that can be utilized across various feature flags, facilitating swift debugging for individual users.
With options for A/B testing, percentage-based rollouts, multivariate tests, and machine learning loops, Hypertune allows for an effortless rollout, testing, and optimization of new features. Additionally, you can log analytics events with type-safe custom payloads and create dynamic funnels and charts within the dashboard to assess the influence of every feature release.
Moreover, the SDK can be initialized with just the necessary feature flags, enabling partial evaluation of flag logic on the edge, thus enhancing both performance and security. This combination of capabilities makes Hypertune a versatile choice for developers aiming to innovate and refine their applications effectively.
