Humanloop Alternatives
Humanloop is sunsetting after joining Anthropic. Here's where five real alternatives stand on price.
Humanloop's own site now leads with an announcement that its team is joining Anthropic, underneath a line stating plainly that the platform is being sunset and that migration help is on the way. No shutdown date is published, but a migration guide already is. Most of the Humanloop alternatives roundups still ranking for this search either skip the acquisition entirely or mention it only in passing. This page verifies Langfuse, LangSmith, Braintrust, Latitude, and HoneyHive against their own current pricing pages, and covers the one gap none of them, or Humanloop before it, ever solved: what your own paying customer gets to see.
Why teams are looking now
What actually happened to Humanloop, and why the timing is different this time
Humanloop described itself as the first development platform for LLM applications, and for a few years that description held up: prompt versioning and side-by-side comparison, automated and human evaluation in the same workspace, and a feedback loop for reviewers to grade real outputs, all under one login. It never published a mid-tier price the way most of its competitors do. Its pricing page shows exactly two options, a Free Trial capped at two members, fifty eval runs, and ten thousand logs a month, and a custom Enterprise tier that starts with a sales conversation. For a team that valued having prompt management, evaluation, and human review in one place, and didn't mind negotiating a number, that combination made sense.
Then Humanloop's own homepage changed to reflect all of that. It now opens with an announcement that the Humanloop team is joining Anthropic, and the line directly beneath it is specific: as the company sunsets the platform, it will keep working with existing customers to make the transition smooth. No exact shutdown date appears anywhere on the page, but a migration guide is already published in the docs, which is a much firmer signal than a vague "we're exploring our options" post most acquisitions produce. Several of the roundups still ranking for "Humanloop alternatives" were written before any of this happened, and the ones written since either leave the acquisition out entirely or reduce it to a single word, "sunsetting," with no quote and no link back to where that word came from.
Five alternatives, verified against their own pricing pages
What Langfuse, LangSmith, Braintrust, Latitude, and HoneyHive actually cost
Every figure below comes from each vendor's own pricing page as of this page's publish date, not a secondhand number a roundup forgot to refresh.
Langfuse
Tracing and evaluation in one open source tool, with a genuinely free self-hosted option and no usage cap. Cloud pricing starts at $0 for the Hobby plan, fifty thousand units a month across two users with thirty days of data access, Core runs $29 a month for a hundred thousand units and unlimited users with ninety days of access, Pro is $199 a month for the same hundred-thousand-unit allowance with three years of access, and Enterprise starts at $2,499 a month. Overage on every paid plan starts at $8 per hundred thousand units and drops at higher volume.
LangSmith
Built by the LangChain team, so it reads LangChain and LangGraph internals natively rather than through a generic hook. Developer is $0 a seat, capped at one seat, for up to five thousand base traces a month before usage pricing kicks in. Plus runs $39 a seat a month with unlimited seats and up to ten thousand base traces included, plus one free small serverless deployment. Enterprise is custom priced with self-hosted and hybrid deployment, custom SSO, and ABAC or RBAC on top. Base traces retain for fourteen days, with a paid option to extend that to four hundred.
Braintrust
Evaluation-first, with unlimited users, projects, datasets, and experiments even on the free Starter tier, which includes ten dollars of model credit, one gigabyte of processed data, ten thousand scores, and fourteen-day retention. Pro is $249 a month flat with no per-seat charge, covering a hundred dollars of model credit, five gigabytes of processed data, fifty thousand scores, and thirty-day retention, with overage priced per gigabyte and per thousand scores past that, and Enterprise has no published price at all.
Latitude
A prompt engineering and agent workflow platform built around a credit system rather than a per-unit trace count. It's also one of the sites that itself ranks for "Humanloop alternatives" with its own comparison post. Starter is free, with twenty thousand credits a month, thirty-day retention, and unlimited seats. Pro is $99 a month for a hundred thousand credits, ninety-day retention, and unlimited seats, with extra credits sold at $20 per ten thousand. Enterprise is custom priced with SAML SSO and compliance reporting.
HoneyHive
The closest structural match to Humanloop's own shape: prompt versioning, automated and human evaluation, and full observability together on one plan, then straight to a custom Enterprise tier with nothing published in between. The Free tier covers ten thousand events a month, up to five users, thirty-day retention, one workspace, and CI/CD integration. Enterprise adds custom usage limits, unlimited users and workspaces, SAML and custom SSO, custom retention, and optional self-hosted or single-tenant deployment, all custom priced.
What none of the six answer
Every one of them scores your agent for you. None of them show your customer what it's worth
Every published rundown of Humanloop alternatives, including the ones written by competing vendors themselves, describes the same audience: an engineering team choosing where to send prompt versions and eval scores now that Humanloop is winding down. None of them ask whether anyone outside that engineering team should ever see any of it. That holds across Langfuse, LangSmith, Braintrust, Latitude, and HoneyHive too, and it held for Humanloop itself before the acquisition: every workspace above is built for the team that shipped the agent, scoped to one account, with no notion of a paying customer as a separate audience with numbers of their own.
If you sell an AI agent inside a product other companies pay for, that gap becomes the next problem right after the migration itself is handled. A customer renewing a contract wants their own deflection rate and cost per resolution, scoped to their own traffic only, and none of the five tools above, or Humanloop, were built with a second tenant layer in mind. AiAgRe's Node SDK connects to a LangChain, LlamaIndex, or CrewAI agent the same way a tracer or an eval tool does, tags each event with an organization identity and a customer identity at the point of ingestion, and turns that into white-labeled dashboard components a customer sees inside your own product instead of a shared login to whichever tool replaced Humanloop. It doesn't replace the prompt management and evaluation work these tools do well: most teams keep one of them running for the team that built the agent, and add AiAgRe for the customer using it.
Match the tool to the job, not the name
Which piece of Humanloop mattered most to you?
Humanloop bundled three jobs into one workspace. Most teams only leaned on one or two of them, and that answer points at a different alternative.
Prompt versioning and comparison was the main job
Langfuse is built around exactly that: versioned prompts, side-by-side comparison, and a free self-hosted option with no usage cap if a team never wants to think about a bill for it. The hosted Hobby plan's fifty-thousand-unit free tier covers most early-stage usage on its own.
Automated eval scoring at real volume was the main job
Braintrust leans hardest into scoring: unlimited experiments even on the free Starter plan, with scores as the metered unit rather than seats or traces. A team running frequent regression evals against a growing dataset outgrows Humanloop's fifty-eval-run trial cap fast, and Braintrust is built for exactly that volume.
Human review queues and reviewer feedback was the main job
HoneyHive keeps human evaluation in the same free plan as automated evals and prompt versioning, the same three-in-one shape Humanloop had, so a reviewer workflow doesn't need a separate tool or a jump straight to an enterprise contract.
FAQs
Humanloop alternatives: frequently asked questions
Common questions from teams migrating off Humanloop after the Anthropic acquisition, or pricing a second tool on top of whichever one they pick.
What actually happened to Humanloop, and why are people searching for alternatives now?
Humanloop's own site now leads with an announcement that the Humanloop team is joining Anthropic. The wording directly underneath it is specific: "As we sunset the Humanloop platform, we will continue to work closely with our customers to make their transition as smooth as possible." That is not a rumor built from a quiet changelog, it is Humanloop's own stated plan, published on the page that used to sell the product. A migration guide is already live in their docs, which is a stronger signal than a vague "we're exploring options" post: teams are searching for Humanloop alternatives because the company that built it just told them, in writing, to go find one.
Is Humanloop shut down already? Can I still use it today?
No specific shutdown date is published anywhere on Humanloop's site as of this page going live, so an existing workspace should still be reachable today. But the framing is different from a company quietly going into maintenance mode: Humanloop is telling customers directly to expect a transition and pointing them at a migration guide rather than promising continued feature work. Treat the lack of a fixed date as a moving deadline, not a reason to wait. The honest planning move is to start evaluating the five tools below now, before a support ticket about API access becomes the thing that forces the decision.
Which Humanloop alternative is the closest match to what Humanloop actually did?
HoneyHive is the closest match, by a fair margin. Humanloop combined prompt versioning, automated and human evaluation, and a feedback loop for reviewers into one product, sold on a free trial plus a custom enterprise tier with nothing public in between. HoneyHive's own pricing page is built the same way: a Free tier with prompt versioning, automated and human evaluations, and full observability together, then straight to custom Enterprise pricing, no published middle plan. Langfuse, LangSmith, and Braintrust are all excellent tools, but each one leans harder into a single piece (tracing, LangChain-native tracing, or evaluation scoring) rather than the same three-in-one shape Humanloop had.
Is Langfuse, LangSmith, Braintrust, Latitude, or HoneyHive cheaper than Humanloop?
That comparison does not quite work, because Humanloop never published a mid-tier price to compare against. Its own pricing page shows only a Free Trial, capped at two members, fifty eval runs, and ten thousand logs a month, and a custom Enterprise tier reached by talking to sales. Every alternative below publishes at least one real paid number: Langfuse's Core plan is $29 a month, Latitude's Pro plan is $99 a month, LangSmith's Plus plan is $39 a seat, and Braintrust's Pro plan is a flat $249 a month. Whichever one you land on, you will know the price before you talk to anyone, which was never true of Humanloop past the free trial.
Does switching away from Humanloop mean losing LangChain, LlamaIndex, or CrewAI support?
No, none of them do: Langfuse, LangSmith, Braintrust, Latitude, and HoneyHive all integrate with LangChain, LlamaIndex, and CrewAI through an SDK hook, the same general pattern Humanloop's own tracing used. Moving off Humanloop does not mean rebuilding an agent that already runs on one of those frameworks, and none of the five alternatives ask for a different tracing approach than the one already in place. AiAgRe's own Node SDK ships the same three integrations, which is why it sits alongside whichever tool replaces Humanloop rather than asking a team to change how the agent is built and traced in the first place.
Do any of these Humanloop alternatives let my own customer see their own dashboard?
No, none of them do. Langfuse, LangSmith, Braintrust, Latitude, and HoneyHive all render results inside a workspace built for your own engineers, with no separate scoped view for a customer outside your company, the same limit Humanloop had before the acquisition. AiAgRe covers that second job specifically: a Node SDK that reads the same kind of trace and eval data these tools already produce and turns it into a white-labeled dashboard your own paying customer sees inside your product, scoped so one customer never sees another customer's numbers.
Can I run AiAgRe alongside whichever Humanloop alternative I pick?
Yes, and that is the usual setup rather than a workaround. AiAgRe's SDK taps the same underlying agent events a tracer or an eval tool already reads, tags each one with an organization and customer identity at ingestion, and does not require removing whichever Humanloop alternative you migrate to. Most teams keep one tool running for prompt management and evaluation, and add AiAgRe's dashboard components for what their own customers see once the agent is live.
Does AiAgRe replace Humanloop or any of its alternatives?
No, and it was never built to. Humanloop, and every alternative on this page, is built for prompt management, evaluation, or tracing for the team that shipped the agent: prompt versions, eval scores, human review queues, request-level traces. AiAgRe starts only once that part is covered, reading the same events a tool like Langfuse or Braintrust already logs and turning them into the deflection rate and cost per resolution your own paying customer sees. Most teams run one of the tools above for the first job and add AiAgRe for the second, rather than asking one tool to do both.
